Before owning the Note 2, I had the S3. The problem with the scared happens on both phones.
When I first got the Note, I removed the sdcard from the S3 and put it straight into the Note.
No media showed up. Formatted in phone, transferred media, all working as it should.
Today, add a video to card, doesn't show. Add a photo, doesn't show.
Format card, transfer media. Nothing shows up.
Am reluctant to buy another card as I tried three Cards in the S3, and the problem was present with all of them.
PS using root explorer I can find all the media, and play them in their respective apps.

Thanks, for some reason that works for my videos, but not with photos and music!!!!
And that is more of a workaround than a solution. Ideally I would like for it to work as it should. Impossible for me to go back to stock as I will always need root to vieww my media(ok, I will probably always be rooted, but I want the option)
Edit: tried again and my music and photos are now showing (using Directory Bind)

Ive had issues like this on my EVO. Try installing a "media scan" app from the market. It rescans all media content on the phone and then if you want you can remove the app after its done. I had 2 years worth of photos on my 16GB SD class 10 and no pictures or video thumbnails / pictures at all would show. Ran the app and fixed all the issues.
I did try a couple of those apps yesterday.I dont know if either one worked.I mean I know nothing showed up, but it was as though they never actually run.
Same issue
:crying:
I tried formatting several times and copied the data back, nothing helped. Also copying files from my comp to the sd card and internal storage in the phone is very slow. I bought the device yesterday, its stock unrooted.
I don't believe media (pictures/video) show up until mediascanner detects them and sticks in some internal database.
So just copying files onto your external card and popping it in isn't going to work.
media scanner is normally triggered during a reboot, and some apps can trigger it. (generally via 'rescan media' buttons).
Also make sure you don't have a .nomedia file there, as that causes media scanner to skip the directory.
( media scanner can really grind on directories with tons of files )

I tried a different memory card from my old Sensation and it read the files perfectly... can any of you help me with the copying speed.. it took me 35 mins to copy 1.20GB... just to be sure i i tried to copy the same date using the same data cable and the same usb port, onto my wildfire, and it copied it pretty fast. Any idea ?

It sounds like the Sensation card just has slower transfer rates. While your wildfire has faster transfer rates but you are experience issues on the phone side.
Just to confirm, you have formatted both cards the same way and one works and the other doesn't? If possible try to format the card from the phone. Have you tried a sandisk card?

Both the cards are Sandisk 8gb cards, both formatted on the Note 2. I transferred data to card A when its in the wildfire, i formatted the card and put it in the note and formatted it again, and tried to copy the same data to card A, it takes more than 3times the amount of time... data transfer has been slow to the card while its in the note
I have read somewhere that there is a " .nomedia " folder somewhere. Delete that and see what happens.

Also on top of that, when you formatted the SDCard did you format in the PC or in your phone through recovery? You will want to format through recovery.
I would recommend upgrading to an ext partition and then formatting again (if you don't need the ext). I have found that even formatting the SDCard on some roms (because the way they work) it doesn't wipe everything and upgrading the to ext actually changes the file system of the SDCard rather than a quick format. Then only copy your media back to the card. Dont copy everything like .android, data, and stuff like that. Just what you want to keep.

Is there any chance you have a counterfeit Sandisk card? Did you buy it from an authorized dealer? If buying from Amazon make sure you only purchase directly from amazon, LLC and not a third party vendor.
For reference which sandisk card do you have what class is it rated at?
Daniel
No the card is legit, i got it in the box when i bought the HTC Sensation and worked fine on the sensation. It has good copying speed if i put it in another device like my wildfire even now. I checked copying speeds yesterday using the same card in my wildfire and my new note, but it takes forever to copy data to the card while its in the Note. I have not rooted my Note yet. Its factory stock as of now.

If your internal memory is slow I would consider that cause for concern. Perhaps try running benchmarks and comparing your results to those in the benchmark thread. It may be worth returning it for another phone if you can't find a solution soon.

Isn't the speed difference just to do with the way the Note 2 connects to the pc? I.E MTP as opposed to mass storage? I seem to recall my G.F's original Note is dog slow at data transfer in MTP but much faster in USB mode....shame the Note 2 can't do this, it's one of my reservations about buying it.

Now it makes sense to me, thanks :good:
Is there any way to connect in USB mode rather than MTP??
Can I ask if anyone else suffers from the same problem as raised in the OP?
I would imagine its not "the norm" and yet I have had the same issue on both the S3 and Note 2.
Whilst, it is now working, I am having to use Directory Bind, for it to do so.
I put in a new 64GB card on Saturday, recognised straight away in Settings/Storage, formatted fine in the phone giving me 59+GB of free space.
Put media on it...nothing shows.
I cant ever see my phone not being rooted so it can be worked around,but it just seems strange that I have had this on both phones and yet nobody else seems to suffer from it.

For whatever reason I don't think Samsung enabled USB mass storage mode on either the S3 or the Note 2. It's the one thing that's holding me back from buying one at the moment because I use iTunes Agent to sync with iTunes, and that requires the device to be in mass storage mode when connected to the pc (or you can take the sd card out and put it in a reader, but I don't like to take the back off too many times as most phones end up getting really creaky). It's a real shame because I'm just itching to get one.
Have a look in the GS3 forum - I think there's a thread where someone has created an app that enables you to toggle USB mass storage mode, but I think you might have to be rooted and have a custom kernel. Don't quote me, that's from memory

There are a couple of threads about this I think now. I browsed some last night. Sorry, I'm only on my phone at the moment so it's a bit awkward to try and find a link for you (what with having a Sensation with only a 4.3" screen They'll be on the first page or two I think.
My girlfriend's original Note had a similar problem with photos and media after connecting an external hard drive. Going into settings/apps and clearing data on the media storage app followed by a reboot sorted the problem for her.
I have 812 pictures in my Camera album on my external Toshiba 32GB Class 10 SD card. When I first got the phone in December, everything worked great, even after transferring from my EVO 3D. Now, whenever I try to access my stuff on my SD card through the Gallery app, it just freezes. I can hit home and exit the app, but back doesn't work and I cannot scroll anywhere. I can still access pictures via ASTRO and save stuff on to it..I just don't anymore, in case it goes corrupt. Any solutions? I tried searching, but no one seems to have the same problem as me..
Lol. Sounds like a simple cache issue with the gallery. Go to settings, application manager, all apps, find gallery, try clearing cache, and if that doesn't solve the problem, delete data. This will not delete your images. I think it may or may not delete your thumbnails. Just scroll over the images again and a thumbnail is remade. Nothing will harm your photos.

hmmm... I would normally say that the 800+ images in one gallery might be the cause of the problem. But you say that it was working fine previously. Even then, I'd recommend to split the images into different folders (maybe based on month they were taken) to minimize the amount of thumbnails that gallery has to process and look through.
I'm assuming you've done the MA6 and MB1 updates. Perhaps upgrading the phone to 4.1.2 caused this? I haven't heard of anything similar on XDA, but I'd stick with kkarson's approach and clear cache from the gallery app. Hope that works for ya!
Already tried clearing the cache and data from the Application Manager, but still the same results. I have a folder of old camera photos from my EVO 3D with 1780 photos in it, and it opens and I can view the photos perfectly fine, with no lag or freezing. But when I open the "Camera" folder on the ext. SD card, it just freezes and I have to go back to the home screen. I just upgraded to MB1 today and still the same results..

Maybe there's corrupted files on the SD card causing the phone to choke when it tries to read them. If you have windows 7 or XP you can put the card in your pc, (with a card reader or usb card reader), then right click on the card and choose properties. Select the tools tab in the properties box. The first option is error checking which will scan the disk and fix errors (if fix errors is checked). However, if there are corrupted files on the SD card it might be going bad and should be reformatted.
I have the same issue. I havent found a fix. I even formatted my external SD card.. didnt help.

I'm looking at a Sandisk 32GB class 10 ultra card that I got right after xmas so it's only 3 mopnths old. It started spitting out corrupt files after only 1 month. Eventually I'll get another card. But if my phone ever random restarts, or suddenly locks up, or I notice media is using a lot of battery, I know if I run scan disk on the card it will show errors. It lasts for a few weeks between formats.
There are also tons of posts from people that have had sd card failures on this phone (also with new cards).

Dont worry you're not alone, theres a thread in general that had a ton of posts and the thread title was "If your sdcard failed on you, what recovery were you on?"
Many have had to purchase 2 or 3 cards until they got one that didnt go bad or corrupted. If you got the sdcard (the one that failed) very recently, you could call the manufacturer and tell them it failed on you, I'm sure they would send a replacement because I've seen others do it and they got their replacements in a timely manner

Hey folks, I have a bit of a problem here. I just recently started having this problem of my micro sd card not being able to be mounted to my GS3 for anything. I don't know what the problem is nor how it can be rectified? So it's known, I'm rooted with the latest CW recovery mod for JB fw version 4.2.1. I tried recovering to factory settings but that doesn't work because I have wiped all my caches. Any ideas as to what I can do to fix this issue? I have no problem losing full, permanent root access by the way but also keep in mind that I currently do not have a computer of any kind. I was able to gain permanent root access when I borrowed my buddy's laptop last week but gave his laptop back.
The message I always see on my phone when I go to manually mount my SD Card in Settings is ..."Your SD Card is ready to be removed."

Honestly, this sounds like your SD Card is in its last days, so to speak. This happens quite frequently and they just do not last forever.
What brand is it?
What is its class and size?
How old is it?
Where did you buy it?
If you boot into CWM, can you mount it there?
Your best bet is to try your best to get any important info off of it, then format it. If you have the space, copy everything important to your Internal SD, then format it through the settings menu. If that doesnt help, you will need to try again from a computer. Use the SD formatter tool from http://www.sdcard.org
I am assuming the card was working fine on your phone and this just started happening recently.

The SD Card is a legit 64GB, Class 10, micro SD Card that I bought not even a year ago from Amazon for $55. It's the card that looks half red and hald grey. I had a ton of stuff on it too... movies, about 2k songs, tv show series, hundreds of pics, paid-for apps, emulated games and more. I think once I flashed a new different rom from the original regular CW 4.2.1, that's when my card was wiped clean. Now I can sometimes go to my sc card in the EZ Explorer Android app and it shows that my card has no files on it whatsoever.
Oh, I also get an error message of something like "cannot mount sd card... error." .... when I mount my card in the CW Recovery screen. I've also tried adding new files to the sd card and when I go back later that day or the next day, those files were wiped clean like they were never written to the card.
So now, the only place I can save files to is my internal phone memory.
So sad and blue...

Yup, sounds like its on its way out. Unless you specifically tell cwm to do so, it doesn't touch your external sd. Some people have made the mistake and wiped out their data by not paying attention to what they're doing.
Anyway, there are data recovery tools you can try to use. Many people have had some success recovering info off of flash memory like that.
Sounds like it was a sandisk, but it should be clearly labelled as such. If its not its probably a knock off. Youd be surprised how many fakes are out there. Even highly reputable sellers have been known to sell cheap knock off sdcards. They don't do it on purpose of course, but I've even seen where they came from stores like Best Buy. The last time I looked I think Samsung, Kingston and Sandisk were the most popular targets for fake sdcard dealers.
This is why I only buy Samsung brand cards, and only from sellers who are Samsung Authorized Dealers. They buy direct from Samsung so you can be confident that you are getting a real one.
Even so, the best ones are still known to fail. I'd google for flash memory data recovery to see if you can rescue some stuff. And I would replace the card.
Its always a good idea to keep a backup even of your sd data. Sorry for your troubles.

I know it's early on but I rooted my Samsung galaxy tab 8.4 and I am trying to do a backup of my apps and I cant do a backup to my external sd card. TB is saying it isn't writeable. I have used the back button and such to manually change the directory. I'm familiar with doing that. I can backup to internal storage but obviously I don't want to waste the space when I have a 64gb micro sd card. Thanks for the help.

I can confirm the same issue. I've verified that the root directory is set to R/W using "Root Explorer" from the play store. For some reason, I can't get TB to see it as R/W, though.
Saving other items to the external card seems to work just fine. Camera saves there, no issues. Weird.

Yea thats what i figured out. So nice to be able to back up to the sd card and the process literally took a minute. Cool find.
I was able to fix this issue by simply installing Folder Mount. When you first open folder mount will offer to repair this permission issue for you. I said yes and it worked. Folder mount also stated this is specific to Sammy 4.4 roms... Just an FYI. Thought I would share.

Unfortunately, it's not something that Samsung decided to do, it's something Google started back in Android 3.2 and is now apparently asking OEMs to follow their lead on - or else the OEMs aren't reading the codebase much, which I think is also a problem.
The external storage permssions were spotted and commented on by Chainfire (he who gave us root, hallowed be his name ) in 2012!

I'm not 100% on this, but I think that the Samsungs are one of the first sets of devices to get KitKat and to have sdcards. (don't know what the status of the gpad 8.3 is) It will be interesting to see if the Gpad 8.3 does the same thing; I'm pretty sure the Tegra Note did, and then EVGA pulled back on their KitKat update due to bugs, of which this was one (glad they called it a bug, but if they'd looked at the code before implementing the changes...)
This issue goes way beyond the sdcard. Remember when your device could be connected to your computer and turn up as a mass storage device, not a media player or a camera?
The MTP protocol originally implemented by Google was hugely troublesome on that score when it was first introduced. There were absolutely insane failure modes. To get an accurate readout of what was on your device you couldn't disconnect from your computer and reconnect, you couldn't disconnect, reboot the Android device and reconnect - nope, you had to reboot your computer.
I haven't thoroughly tested failure modes but at least the warning on copy from PC to Android works correctly now.
When first implemented by Google, file deletions on in Android were not reported to the computer connected to it if they occurred while connected. So you could move a folder and then try to copy files that didn't exist, and Android wouldn't report the file was not there.
This is an example of silent failure, which is the worst possible failure mode. It gets beaten into the heads (or once did) of programmers that you always produce and report an exception on failure. Not doing so is negligent and might be actionable depending on the context.
I just deleted a file from the Samsung and it's taken more than 30 seconds for the Windows system to get information on what's on the Samsung.
Great - I also couldn't enumerate my local disk drives while I waited, more than 3 minutes (i7-2600k, 8 G ram - not a PC side issue!) I finally disconnected and reconnected the USB cable and was able to get my disks to populate immediately on disconnect, and an accurate poll from the Samsung on reconnect.
I suspect that Google's 'fix' for the not-notifying-on-delete bug is to throw a disk not ready message back at the host system.
So, why does Google not see any of the following as important?
- easy local disk mounting
- viable sdcard use
- well-written MTP implementation
I don't think it's about the cash - sure, Google's selling a few books and a few movies and such, but they're really an advertising broker; the revenue from that isn't why they're worth gazillions.
I think it's actually much more insane than that: Google is all about big data and the supremacy of databases over all else.
Including files themselves - Google wants to drive toward a world where files don't exist, only pointers in databases exist.
http://glasskeys.com/2011/02/28/why-google-uses-mtp-instead-of-usb-file-transfer-on-android-3/
is a perspective on MTP that is essentially diametrically opposed to mine - it's quoting Google as pointing out that there is both simplicity and allegedly a greater degree of security from MTP.
The security comes from the filesystem retaining 'nix style ACLs and helping to maintain sandboxing between applications by not exposing storage as a fat32 filesystem and thereby giving up granular access controls.

(As an example of silent failure that I think may be the subject of civil litigation: the flaw that broke SSL/TLS validation on most Apple devices - phones, tablets and OS X based computers. If you look at the code, it's blindingly clear what happened.

This flaw may well explain the Snowden documents that indicate that the NSA has access to any Apple device at will. When those documents were first being reviewed, there were two responses:
- it isn't true
- Apple is in bed with the NSA.
Ignoring a bug that easy to spot in a functional test for years tends to make me wonder if the second explanation may not hold water.)
Hopefully this can help someone. I couldn't edit my *.xml file even though I am ROOTED. But I found this:
https://play.google.com/store/apps/details?id=nextapp.sdfix
and it worked!! Now Titanium Backup is able to write successfully to my sdcard.
The app works great. I would recommend it for anyone on 4.4

PRESOLVED: My Tab is possessed by the devil!
When I tried to write a file to my Galaxy Tab Pro 8.4's external SD card with Astro and it wouldn't work I was flustered. A little research turned up the crippled SD support in KitKat and how to fix things with the simple platform.xml hack. I did that, and all was right with the world again.
Then I got another 8.4, and actually cloned the first one to the second one with a nandroid backup. I also moved my SD card from the first to the second. Eventually I sold the first one and am just left with the second one. But somewhere along the way I lost the ability to write to the SD card, and I can't get it back!
The hacked platform.xml file was of course cloned along with everything else, but it just doesn't work. What's just as bad, or worse, is that apps which should write to external SD even without the hack (and which did, prior to this issue developing), such as Samsung's My Files, and Root Explorer, also are no longer able to!!!!
So to try and fix things, I flashed this ROM to my Tab: http://forum.xda-developers.com/showthread.php?t=2698460 But I still can't write to external SD, even with My Files!
Here's another problem, which may or may not be related: I also can't write to the external SD with the Tab connected to my computer. With a small file, the progress bar immediately jumps to 100% but then freezes and after a long time the copy times out with the message, "The device has either stopped responding or has been disconnected". With a large file the progress bar plods along, first at a normal speed but gradually getting slower and slower, until at some point it stops moving and the copy times out.
Please, I beg of you, help me exorcise my demon Tab!
SOLUTION: Before actually posting this plea for help, I re-formatted my SD card (in the Tab) and all functionality is restored. I post this at risk of making myself look like an idiot, in hopes that it might save someone else's hair.
Good on you for posting the problem and the solution. I doubt you'll be the only person to experience this.

From that comment it seems we need more bald users as no risk testers.

Just wanted to add a postscript for anyone who might have a similar issue. I thought this problem was solved, as described above. Then a few days later when I booted up my tab, the SD card was shown as blank/unformatted. At that point I did some more digging and determined that it was actually a counterfeit 32GB card, based on an 8GB card. Got a refund, threw it in the trash and ordered a new 64GB card. Caveat emptor!
To make a long story short, I took some irreplaceable pictures today that disappeared.
I have my camera saving to my 64gb memory card. I took a few pictures and a couple of panoramas and they ended up showing up glitchy and useless.
They didn't appear in the gallery with the exception of a few images.
It looked odd.
I rebooted the phone and tried to go into the gallery and they just weren't there. The previews showed up momentarily and then they vanished.
Now when I try to take a photo to go to my external memory, it works fine. It didn't pre-reboot.
Is there a method of:
A: Recovering my lost 10-15 images.
B: Ensuring that this doesn't happen in the future.
For the record, my card seems to be working fine. Music on it loads up quickly as well as any other images that I loaded onto it. Files open and there is zero lag. I don't suspect that the card is corrupted or anything.
Thanks guys.

You could try something like Recuva: https://www.piriform.com/recuva
I successfully used that to restore files deleted from microSD cards a few years back.

Thanks!
I'm unfortunately on a Mac. Guess I'll boot into boot camp and install it and give it a go.
I hope the pictures actually existed as files though and not some cached object.
Update:
Overnight, the saving issue arose again. I'm forced to use internal storage when using my camera.
I've seen this problem before. So SD cards don't work well with Samsung devices. I bought a Samsung SD card and never seem this problem again. I recommend you do the same.

I wish I wasn't broke :/
I'm using a SanDisk 64gb. Guess I've gotta dig up some cash and get a Samsung.
I don't see how this is an issue though.
What is your card formatted in? My current is in exfat. I'm thinking the format may be an issue.
It may be a kitkat issue. Google "kitkat SD card write". Root users are using a fix that sets permissions so the sd card can be written to by all apps as expected.

Right before I came across your post, I found some info on the kitkat issue with sd cards. I'm guessing that's what's causing this problem. Odd because it's the default Samsung camera that's messing up.
Oh, how I miss root. I just hope we get root soon. I'm pretty close to selling this phone and hopping on Tmobile.
I had this problem happen with very VERY irreplaceable pictures, on my backpacking trip to china, one of the most irreplaceable pictures of my entire life was taken, appeared glitchy in gallery, phone reset and it was gone.
after taking out the SD card, and doing many deep scans to try and recover the deleted pictures, it seems the pictures arent there, which leads me to believe it somehow tried to save it in internal memory (which cant be mounted as a drive, so cannot be recovered).
if you can somehow flash an older version of android (like 2.xx) you can mount your phone as a drive, and then attempt to recover deleted data from your internal SD..
yeah all i can say is ,,|,, you samsung.
I too have the same problems as the OP. And I am on SAMSUNG micro SD card! Guess it is one of those first batch gremlins?
However, I think the problem has gone away after I switch on the image "preview" option. Give it a try.
I had the same issue with a 64gGB SanDisk micro SD card. The camera would seem as if it was taking pictures but nothing was actually saved; they just shows as corrupted files in the gallery. I lost countless irreplaceable images from our honeymoon because of this. Once I switched to a 32GB Samsung micro SD card I never had the issue again, also saving the pictures directly to the internal memory solved the problem. I use the SD card for music as well so it has to be something with the phone writing to the SD card. From what I've read it's a issue with the compatability with samsung and non samsung sd cards for some reason.

Never had this issue with any of my Samsung phones (S2, S4, and now the Note 4). I'm using a SanDisk Class 10 32GB. I'd recommend pulling the files off the SD and doing a format. Download the App SD Maid as well for routine maintenance on your SD. Good luck.
My 64GB SanDisk SD card was giving unexpected unmounted errors, so I picked up a Samsung 64GB SD card. The unexpected unmount errors went away, but now I have this problem. Pictures are not saving to the SD card correctly. Sometimes it says media not found. Others the preview/thumbnail looks fine but the full view is just grey.
I am going to try saving to internal memory and manually moving to the SD card as I run out of room.
