I decided to format my SD Card to try to clear up several problems I've been having. I'm not sure if it helped yet, but that's not what on concerned about at the moment.
Copying the data from my card and formatting it went well enough. Copying the data back to the card, however, was a totally nightmare.
The card would only take a small amount of data at a time before freezing up the windows explorer session, at which time I would have to unmount my card, disconnect the USB cable, and then re mount and start the explorer session over again. The limit seemed to be just over 100 MB, sometimes a lot less.
Copying 5GB of data back 100mb at a time took ALL MORNING. All morning of plugging and unplugging. Mounting and unmounting.
What could be going on here? Bad SD card? Bad USB drivers or connection? I'm using a solid aftermarket cable.

I have always had this issue also, with stock sdcard. If I tried too much data at one my explorer.exe would crash... I haven't figured out a solution yet either.

Try putting the card in the sd slot of the pc...assuming you have. Lightning fast and easy. If u don't have, they are cheap. Also, the class of the sd card matters too. Google it.

I've done that before. It never works. I'm assuming because they need to be formatted differently for windows and Android. Putting my phone's SD card in my PC usually locks up the PC explorer.

Hello!
I'm wondering if there's anything out there that does what Apps2SD+ does but takes out the unfortunate bit of me needing to reformat and restore every other day because of the SD card becoming damaged.
Thanks guys!
Are you disconnecting your phone from pc only while in "charge only" mode?
That is the main reason for corrupted sd cards, there are no issues with a2sd+
You mean if I plug the phone into my computer to charge only, there's a step I have to take before I simply pull the plug?
No, file transfer to/from sd card (disk drive mode), you need to return it to "charge only" before unplugging usb, as it can cause sd card to unmount by itself, and finally stop working
Ahh. I see. Thank you, I'll do that then from now on.

Hmm.. did everything right and it broke again. *sigh* now to start the several hour long process of extracting everything off the damaged MicroSD card that I want, formatting it (which only Windows XP can do for some reason) and restoring the ROM on the internal phone storage (since it now can't boot up with or without the damaged card in).
Apps2SD+ is just too great to abandon for this reason, so I guess I won't use disk mode again. Kind of a pain in the *** if I want to transfer anything big. Dropbox is pretty awesome, but it'll only get you so far.
This makes me wonder if there's some kind of threshold or number of apps you can have installed through Apps2SD+ where if you do anything over that number, there's just too much going on to enter and exit disk mode successfully.

there must be somthing wrong with your sd card pal. im using apps2sd+ with a 1gig ext3 partiton, i must have 2 or 300 apps easly and its never happened to me, maybe you should move the dalvik cache back to your fone as the constant i/o does wear down sd cards quickly

And again today... I've finally retired my 8gig MicroSD (the problematic one) to my Canon. I guess it's that 2nd partition that just pushes it over the edge. Or it's just plain defective, as has been suggested. Looks like I'll be falling back on the 4gig the Desire came with. It won't be my main music / podcast player, so that capacity should be more than enough.
Okay guys so, I haven't been able to determine my issue currently. But so I'm pretty sure rom doesn't matter. I'm on wicked currently, but for whatever reason when I have much storage on my micro SD, it starts to behave oddly. It's a patriot 32 gig. When I go to open the gallery with as little as 4 gigs on the external. It'll freeze up and may or may not ever load my pictures. It refused to play a video I'd just recorded. And when I plugg the phone into the computer to try to transfer files it behaves oddly. Sometimes I'll open a folder, it shows it is empty, and then when I go to copy said empty folder it will start to move the info and show there actually is a lot of stuff in the folder. Sometimes it'll stop transferring and say 'data type cannot be identified' or something to that effect. I *think* this is only with my external SD. I've reformatted several times without luck any info on this? Thanks guys.

Have you tried a different SD card?
Problem:
I'll connect my phone to my computer and open the SD card (32gb) to view it and several of the folders names have been changed and they all start with a "u" now (see below for example)?? On top of that, everything in those folders is now missing... There is also a new folder called "Lost Dir" with a bunch of files in it with just numbers for names, no extension though. I'll delete the folders and they reappear on the next restart..... So I usually end up reformatting the SD card and it's good for a few days and then does it again.
Example:
Downloads is now uownloads (with a funky symbol next to it)
Data is now uata
TWRP is now uWRP
ect...
This has been happening for a little over a month... with different ROM's, so it's not a ROM issue. Could it be Fast Charge?? Could it be the kernel I'm using as I always use the same kernel?
Anyone else have this problem that could shed some light on it for me? I'd like to figure out what is causing this so I can fix it, or not repeat it.
Thanks, Jason
Sounds like the card is failing, or the controller is.
Try reformatting it in your computer using a USB adapter, not a built in reader. Do a full, not fast, format.
Could also try running Scandisk.
What brand card?
Obviously, trying a different card can sort this out quickly.
Bad card. Is it a 32GB card by chance?
Formatting will only be a temporary solution. Eventuality the errors will pop up again

Yeah, 32gb SanDisk.
All signs are pointing to this, I'll probably pick up a new one this week.
Thanks for the replies!
You may be able to have the card replaced for free under warranty.
I have a SanDisk 32GB microSD card. I originally had one at launch but after a few months, I had a terrible case of Media Server constantly running in the background sucking up all of my battery. I got the card replaced by SanDisk as per a lot of discussions on the forum.
Its bee fine with this new card for over 5 months. Now, out of nowhere, I'm noticing that my Galaxy is EATING my data. Slowly over time more pictures and music files on my SD card are being wiped out. The files stay on the card, but read as 0 bytes and I can't open them.
Last week I lost an entire folder of pictures. No big deal, thats backed up.
This week I noticed half my music library is now a bunch of 0 byte files. What on earth?
I'm going to go home and copy my backup over SD card after reformatting and will report back. But what gives? What is this nonsense and why would it be doing this? I haven't dropped my phone or installed any crazy stuff on it as of late either.
EDIT:
I'm on stock ROM with AutoChainFire root. 4.1.2

What rom you are running? What format you have in your sd card, ie exFAT, FAT32 or NTFS? Highly recommend to format you sd card to FAT32.

The card may be damaged or corrupted..
Not uncommon for SanDisk...
Try a clean format to FAT32 and test again...
If the same conditions exist...a replacement may be in order...g

How should I properly clean format?
Because I tried to format straight from the phone. But after 3 tries, it wasn't actually formatting the damn card even though it said it was. I removed the card and connected it to a hub on a PC to do it through Windows.
I know that it technically shouldn't matter. A format is a format. But is there any reason why I ~should~ do it through the phone at all? Or why it would even act funky like that?
I think I need to do a clean install on my phone too. Just to be sure.
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.

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.
