16 GB micro SD card causing file explorer to crawl

i have a SanDisk 16gb micro SD card and recently it has been making file explorer crawl and crash when im trying to navigate my data. i tried using total commander to access the memory card hoping that it was just file explorer giving me a hard time and it is doing almost the same thing in total commander (it is slightly more manageable in total commander) this did not start happening untill a few weeks ago. is there a chance that a corrupted file would be causing this issue or possibly i just have the card too full up? (its not at capacity yet but it is about 1 gig away)
is anybody else having this problem or does anyone have some insight for me? any help is much appreciated.

Chances are it's only a Class 2 card. Those are extremely sllllllooooooowwwww.

correct, it is class 2, but it used to be no problem whatsoever untill a week or so ago, anyone else got any clues?

It could be a combination of the fact that it's Class 2 and you loaded it to near capacity. I wouldn't think a corrupted file could do that, although I might be wrong. It could also just be a bad card. I've gotten a few that work fine for a couple days and then stop working completely. I would go with a higher class in the future (or a lower capacity Class 2 card).

Perform a CheckDisk/Scandisk(equivalent for your OS) on the card either via a Card Reader w/ an adapter, or connecting your phone to your PC in Disk Mode. Kind of fishy that it would happen all of a sudden. Flash media doesn't have noticeable file fragmentation issues.
You could also back up everything you have on the card, reformat the card, and reload everything back to it.
Hopefully this may help.

thanks for your responses, i will definately buy a higher class card in the future. how exactly do i perform that scan on my card though? i have an sd adapter so i can plug it directly into my computer. i use vista for my OS

Plug the card into the adapter, and in file explorer on your PC, right-click on the drive that is the SD card. Choose "properties", then the "tools" tab. There you will see the option to "check this drive for errors"
And for future reference, this is the same procedure you would use to do a "chkdsk" on any drive connected to your pc. It will check for signs of defects to the physical media.

[Q] Multiple Problems on Galaxy Note 2. Kindly help to find out the best solution!

[Galaxy Note II]
I have some questions/problems and I need solutions from the Pros here:
Maybe I'm outdated or something but I didnt own S3 and my old S2 doesnt have these problems... now that I have used Note 2 for 1 week, I start noticing that Google and Samsung have changed the policy of storage management in their new devices...
1st problem:
- Phone memory is no longer divide into 2 partition which is good, so we can fully use that 16GB BUT what to do if 16GB is finished?
- They (not sure Google or Samsung) removed the "move to SD" option in the application manager.
- Means when 16GB is finished, nothing we can do but to uninstall some apps to free up the space, and there is NO way to move files like game datas into our "external microSD card" and I have searched everywhere in the net and none of them have solution for this at the moment and all apps (App2SD, GL to SD etc.) in Google Play does NOT support S3/Note2.
2nd problem:
- USB Ultilities/ USB Mass Storage (UMS) mode is no longer available?! (WTF??!? again not sure if this is Google or Samsung's fault)
- Now tell me how are we gonna transfer our huge files from Phone/ExSDcard to our computer? MTP? **** MTP, you probably need years to transfer big files using that mode...
- I have studied that, due to the non-partition phone memory, phone memory is NO LONGER able/impossible to be unmount and remount to computer as a mass storage. So nothing we can do with internal storage.
- BUT why the hell Samsung cant even include an UMS mode for only the "External microSD card"?
- Can the Pros here tell me HOW do you transfer your huge files from phone/ExSDcard to computer and vice versa (without having to take out the microSD card and plug it into computer)?
3rd problem:
- I have just tried to connect my pendrive to my Note 2 via OTG cable and it works.
- BUT after disconnected it from the phone, there is a problem charging the phone. I have to reboot the phone to make it back to normal.
- Do you have this problem too? can anyone please confirm this because I want to know whether it's firmware problem or hardware problem.
- I found someone having the same problem like this in XDA forum btw.
Thanks a lot and your reply, help and suggestions are really much appreciated! :good:

anyone please?

Thanks for the reply...
Can you share which apps you are using for those solution?

i would like to answer no. 2
are you using mac? if yes (i myself use imac) , there are no other way to make it as a 'pure' usb but install windows on your parallels or vmware. after that, install newest samsung driver (search it in note2 forum,sorry i forgot which thread ...) on that windows (i also use this driver on my lenovo notebook with win8), plug in your note2 ( i use sandisk 64GB and it detect it well), and there you go, enjoy your usb.
but if you only want to drag some music, pics, film.. you can use samsung kies for mac.

I do have these same issue(1), on my note 2... need an serious help to enable to move the apps to sd card.

MTP transfer was standard from day 1 for the SGS3. There's an app called something like Easy UMS Transfer on some SGS3 custom ROMs (Foxhound is one) and it apparently works on the N2.
TBH I have no problems with MTP. Have yet to find a file I can't transfer, and it took under 3 minutes to transfer 2 900MB ROMs last night.
Airdroid or (better) Remote Web Desktop may also be of use to you.

Would like to answer question 2: file transfer speed is damn good I tried more than 3gb file it took couple of minutes.
So need to worry abt the transfer speed.
Incase of external card it again depends on the card class like class 10 or class 4.
I prefer class 10 for any kind of file and video recordings.

For question 3 I think its better you try eject the volume first using unmount option under srorage.
I never tried but you can try if your pen drive appears under storage area.

[Q] Cant transfer ANYTHING to external SD!!

I have tried transferring files via My Files app, File Expert, Astro, as well as connecting to PC via USB... it always gives an error and says unable to write! I have also tried to transfer from internal to external SD, still just says "copying failed". I've also tried via Kies.
The external SD is not locked as I used it in a previous phone, and the Note 2 can see the files on it (and play the music).
What's going on?!?

Uninstall and reinstall drivers worked for me, I don't know what happened I went they the same deal yesterday.

My card worked perfectly for a while, then became write protected for no apparent reason and I started getting the same error message you are getting. I had to copy the contents to my PC then reformat SD card in the phone. After that it worked normally again and I was able to copy my data back to the phone .

For anyone with a similar problem described above, please try another USB cable. In some systems, the white USB cable that comes with this phone doesn't send data to computers properly - it supplies power but has problems with data.
Many people have reported this. I just confirmed it on my system. I connected my Note 2 to my system with 5 other usb cords and my system found the device every time. When I used Samsung's white usb cable the computer didn't see the Note 2.
Either Samsung did something with this usb cable or they're sending a lot of defective usb cables out.

I am using a different cable and it detects the card, but as the others have said, it is "write protected" randomly.
I have even transferred all data to internal, formatted my external SD (via the Note 2 option), moved everything back over, it wrote files fine for a few days, and now it is auto-write-protected again. This is kind of ridiculous and is really a hassle especially seeing as most people use external cards for media.
Bump for a fix hopefully... We should not have to reformat every few days just to be able to use our cards.

Thanks for the clarification. I haven't experienced this issue (yet) and agree this is not related to the white Samsung USB cord..
I wonder if the phone has problems with certain cards. What type, brand and size memory card are you guys who are experiencing this problem using?

I'm able to transfer files to and from SD card but not while in recovery mode. Only some files show on SD card while in recovery mode, backups fail, etc.. any ideas?

Getting a 64GB Card to work Properly with the S3

Samsung Galaxy S3 Canadian 747 Version and 64GB microSD cards.
New Information: It seems that the S3 on 4.1.1 has issues with both 32 and 64GB cards when you allow "mediaserver" to catalog a complex library. Any card you use for music with the S3 has to be formatted FAT32 and has to have a .nomedia file to prevent Mediaserver form cataloging it. This information comes from 2 independent Galaxy S3s on 2 networks. I currently have a Sandisk 64GB card in my S3 and have been using it for a month without the slightest issue since I formatted FAT32 and prevented cataloging with a .nomedia file.
Summary 1: 64GB cards are currently a bag of hurt ......IMO on Jelly Bean 4.1.1 the Samsung Galaxy S3 does not properly support many 64GB cards. Don't buy them unless you can return and don't waste your time trying to get them to work if they generate any errors(they will only get worse). There seems to be more than 1 problem also .... one is that hard use seems to corrupt some cards and mediaserver also corrupts the card.
Summary 2: Tried Kingston 64GB Class 10 card (SDCX10/64GB) card in may hands it was unstable in this phone either because I got a bad one or due to incompatibility. Wasn't about to try another one.
Summary 3: I tested a 64GB SanDisk microSD card formatted FAT32 and it passed all the stress tests and gave no errors even with the card full of music and repeated switching/manipulations of files on both the phone and the PC. No dismounts,no scandisk errors, no Android mount checking messages.
Hello All ...... Here is how I got a 64GB card to work in the Samsung Galaxy S3 747. It worked for me but may or may not work for you so make sure you can return any card you buy because it is common to have issues.
NOTE1: The S3 does not support exFAT, the format that both Windows 7 and the S3 defaults to when formatting. The exFAT format may appear to work but sooner or later your card won't mount properly on your phone. The card must be formatted FAT32 for Android 4.1.1 (Check other posts on how to do this)
NOTE2: The Samsung default player and the Mediaserver App are buggy pieces of crap for large libraries ... Use PowerAmp media player instead from the play store.
NOTE 3:If you have messed about with exFAT and syncing using a Media Player Program you need to format your card FAT32 on your computer AND remove the offending software and shut down your computer and restart it.
1) First you need to have a look at what you are using to read your microSD card on your PC and if it is more than a year old you should probably throw it out or remember to never put your 64GB card in it. With the right SD card reader you can also take the card out of the phone and transfer directly using the reader but it may not work.
2) If you have programs intercepting your USB mass storage connections on your PC, you need to disable them .... The program I use for music is Media Monkey 4 and if you have the MM4 mass storage sync addins active, not only will you not be able to sync with MM4, you will not be able to transfer files to your phone by any method until all the Mass Storage Hooks are removed. Other program like ITunes may or may not have similar issues. This is important because these programs and hooks can actually render the card inoperable. Media Monkey for example will try to sync the tag track name instead of the actual name to microSD and this can result in improper characters and path lengths in created files that can destroy the card.
3) It is best to just take the card out of the phone and copy all your tracks direct to the card using Windows 7. Make sure you have a current reader that supports 64GB. The sad take home message is that you won't be able to sync using a media file manager but with 64GB of storage you probably don't need to anyway, Just copy your whole library over and forget about it until you get new tracks.
4) Create a directory called Music on your SD card and create or copy a file called .nomedia to that directory. This is required because the Android program Mediaserver will try to catalog this directory if you don't and mediaserver is buggy with music files. This means the Samsung Music Player App won't see your tracks and you will have to use PowerAmp to play tracks (Samsung player is actually pretty good but PowerAmp is better anyway)
5) Copy all your tracks using Windows 7 and a card reader. It is way faster than MTP anyway. Check that the files are there then "Safely remove hardware" the card, remove, and re-insert. If you get errors just take the card back to the store.... don't waste your time (unless you aren't sure about your reader) Run chkdsk (without fix option). If you have errors just take the card back to the store.... don't waste any more time. "Safely remove hardware" and remove the card.
4) Put the card in the phone and carefully watch the status bar. If your card wont mount, or gives you a "checking the card" message the card will never work in your phone so just take it back to the store.. Dismount your card and remove it from the phone.
5) Reinsert the card into your card reader on your PC . If you get errors just take the card back to the store.... don't waste your time Run chkdsk (without fix option). If you have errors just take the card back to the store.... don't waste any more time. "Safely remove hardware" and remove the card and put it back into your phone..
7) If your phone gets laggy when you put the card in it means that you didn't correctly put a .nomedia file into the music directory on your microSD. The buggy mediaserver program is trying to catalog your music and it may corrupt or destroy your card if you have a big collection.
8) Open PowerAMP and do a full rescan. If your card and music are intact a full rescan of 10,000 tracks shouldn't take more than 5 min. If it does your card is struggling or you still have mediaserver trying to catalog the tracks. After catloging is finished test your media library using the PowerAmp specifically looking for albums with unknown artists or album art that doesn't load. If you know that every track has uncorrupted tags and uncorrupted album art on your computer then missing art and unknown artists mean you have a problem with FAT32, the card or your phone. Back to the store with your card, but it is really easy to have corrupt tracks in your library so check that if you like.
9) Note that with a full 64 GB card of music the PowerAmp will take up to 5 minutes to catalog your tracks and your PowerAmp will not work properly during this time AND your battery will be sucked down at an incredible rate due to 100% CPU usage. If you make the mistake of cataloging tracks with PowerAMP with mediaserver active at the same time your phone will grind to a halt and neither PowerAmp or Stock may ever finish cataloging and your battery will be sucked dry for days on end.
10) Remember to never ever stick your microSD card into any reader older than 6 months to a year .... Actually I wouldn't stick it in any reader at all for a year or 2. Writing a single file with a unsupported reader can cause corruption or wipe the entire drive.
11) Enjoy your music collection on your phone and be glad you don't have to use any of the crappy on-line music storage solutions which are SLOW, UN-CATALOGED and WiFi/Carrier DEPENDENT, and which can take weeks to upload your tracks.

I simply formatted my 64GB card on my MacBook Pro and had no problems since.

Put in the card into phone, and format from within phone. Been using a 64 GB card formatted from within phone for the last couple months with no issues, recording huge videos in full HD with no issues.

Lies. The SGS3 will format it as FAT32 with a 4GB file size limit.
Did you do this on a stock ROM?

I had a ton of issues getting my 64gb card to work. It would error out when trying to format from the phone. I ended up have to do a deep format that took forever and then it finally showed up as working on my phone.

Hi Guys, I'm having a slightly different problem with my 64gb micro SD in my Galaxy S3. I have tried formatting the SD card in various ways, fat32 exfat and formating it on the S3. It seems to format fine and I can create a folder on it called music. I can then copy as many songs as I like on there. It all seems to be fine until I put it back in my S3. When I then go to play the songs, it has deleted a bunch of my songs. No matter how many songs I put on the card, it seems to reduce it down to about 4gb of music.
If I then plug it back into the memory card reader, the music folder is still there as well as all of the artists folders, but the ones that have had the songs deleted have no tracks in the folders. They have just vanished?! I do not get any error messages at any point in the process.
Can anyone offer any explanation?
Cheers.

I had a ton of trouble with random corrupt and missing files with my 64Gb card. Then I used guiformat on my windows PC and formatted it from exfat to fat32. Not one single problem from then on (about 6 months of heavy use). 2 cents aimed at you to hit or miss good luck.

Tried this last night. I put 8.16gb of music on the SD card, put it in my phone and not all of the songs were there. I have put the SD card back in my PC and there is now only 3.94gb of music on there?!
not good

Reformatting to fat32 defeats one of the great features of xfat on the cards, namely you can put movies on over 4gig. I have used sandisk 64gb cards and they worked out of the box on 3 s3's. As a side note it sounds like media scanner is stopping on your phone and not finding all your music. If you move it back to pc are all files there.. If so check for some weird files that are breaking media scanner. If not you may have a bad or counterfit card. Did you get it from a reputable place. Also, you are not trying to put over 4g in one directory are you? You should have subdirectories under music in the normal format that windows media player writes... ie artist/album/songs. I have over 11gb of music on my daughters phone and 13.7gb on mine. How many songs does it show when you play a song under the "all songs" tab of music player? See below I have 1913 songs.

Hey all, I'm also having this issue. I have formatted my card to Fat32, and was using it last night in poweramp with no issues, then suddenly it couldn't read files and was rescanning my library, this morning it worked but about half my music was gone. I put the sccard in the computer (I'm running mac) and I've attached the picture of what shows up, note the strange coded files...
I've tried creating a .nomedia however mac won't let me do that in house, and I've also run into problems renaming it on the phone..

i love people posting on drugs

Hello: Did you ever figure your problem out? The exact same thing is happening to me. DWS

Read the first post
I am very sorry to say that there is no way to get this to work on Android 4.1.1 except formatting FAT32 AND putting a .nonmedia file in your top level music directory and using PowerAmp. Nothing else is stable in the long term.
I haven't had one issue in almost 8 months where previously they were almost daily.
Mediaserver is a very badly written Android sys app that can't handle complex music libraries .... it is that simple.
This may be fixed in Android 4.1.2 but Google has become so sloppy these days and there are no release notes .... I am simply to scared to even try upgrading a phone that works perfectly (with tweaks)

Ok, so I've followed all the steps, but now it seems like I'm going to have to find another workaround, or a better alarm clock app that doesn' reference the stock music player when looking for music to use as the alarm tone. So what is the workaround? Or is it safe for me to allow the stock music player to catalog the music? Kind pisses me off, because it took me half a day to fumble phuck around just getting all 9743 tunes onto this card, and to get gonemad music player to at least see the files(I still need to figure out how to get it to scan the folder with the .nomedia file in it)...
If the device is advertised as supporting a 64gb card from the factory why on earth does it take so much mental masturbation to make it work

I'm Having the same issues with my samsung 64gb card. My Sandisk 32gb held up like a champ but this new card keeps deleting my music. I can't figure out what I'm doing differently.

I will load up about 9gb's of songs and they go on ok, but when I go to play them on my NOTE 3 , some will play and others start showing up errors saying cant play that type of file . I will take the card out and look at those songs in that folder in DETAILS and notice about 100 songs now have 0's under the duration of the song but still show the size of the mp3 , however it wont even play now on the computer . Anyone know why this is happening? Is it because of the 4.4.2 KitKat update. Is there a work around ?
Also in the first part if this thread , he talks about making a .nomedia file . So how do you do that ? Is that a note file ? a renamed mp3 file ? How do I create this file and put in it my music folder?
Another suggestion was not to put over 4gb of music into one subfolder . Guess I will try that next .
I am on a Note 3 4.4.2 with a 64gb Samsung MicroSDXC UHS-I card .

One way to do that is open a Windows folder and right click in the white-space of the folder to create a TXT file and name it something like test.txt. Don't add anything to the file, just save it. Then go up one directory (folder) level and on the folder where the TXT file is, right click on this subfolder while holding down the SHIFT key. Select "Open command Window here". Then key in at the Windows command prompt "rename test.txt .nomedia" (without the quotes). Now close the command prompt and open the same folder with Windows explorer and you'll see you now have the .nomedia file.
P.S. I am here because I just purchased a Blu Studio 5.5s which seems (as advertized) to support a 64GB card. I was having the same problems with long named MP3 files but my problem showed up while adding a large music directory to the card while it was plugged into a cardreader in Windows 7. Toward the end of an 11GB copy I started seeing the blank folders and zero byte music files while copying to the card outside of the Android device, so I may have a flakey card. While this card is in the phone, files are copied to the SD card as expected from the Android OS and I can successfully move applications to it through the Android interface, but I can't add very much of my music collection to it before the zero byte size files and blank folders start appearing. It starts showing problems when I copy much more than 8G to the Music directory. I removed the card, backed up the Android files, then ran chkdsk /F which some say don't run and that found some bad files and supposedly fixed the disk but the last group of MP3 folders at that point turned to ghosted icons. Knowing that wouldn't do, I then reformatted the 64G as exFAT, copied all the files this time without any problem, but unfortunately the Blu would not read the card at all then, apparently not supporting exFAT. I then removed the card again and used EasUS Partition Manager on Windows 7 to format to its original Fat32, copied all the Android system files to it from a backup and still had the issues once I started again trying toy copy files when the Music directory got a bit over 8G. I am going to try it again after I order a new memory card. Ironically the card I have in it now is a Samsung.

External Memory File Copying reading error

After transferring additional mp3 files (by drag and drop method) to external 64GB storage to pay the music Tablet cannot recognize and play them. Is that something to do with 64 GB?

Well, ... if Samsung says that the Tablet can handle a 64GB SD-Card, than the SD-Card isn't the problem.
Did the Tablet recognize the SD-Card before you copied the MP3s to the SD-Card?
Where did you copy the MP3s to? Which directory?

What class is the sd card? Most brands under class 10 gives random problems in Samsung Devices....especially the tabs. I also just drag and dropped all my music to my external. Roughly 700+ songs, all formatted to 112-128 kbps mp3. That reduces the size dramatically without suffering quality loss, on a 32gb class 10 external.

Yes, it did recognize the external card. I used Drag and drop method, creating separate audio folder. Problems start when I want do add some files to this folder. Samsung says that it cannot recognize the file. By the way some files I have are FLAC not mp3. adding additional mp3 cases problem

It Patriot class 10, 64GB Some files in the folder are flac type I mix them with mp3 . looks like adding mp3 to this folder (which already has 29GB ) causes the problem

I think it's quite simple. If you copy the MP3 files to the internal storage (not all of them, just a fem files for testing purpose),
and the tablet recognizes the files (and you can open them), than you don't have a problem with the MP3s. But if the tablet
still won't recognize the files on internal storage, than something seems to be wrong with your files.
And then I would do it as described by ReeceWyld. re-format them to a max. of 128kbps and try again.

I think there is a problem with memory management in the tablet for such a size like 64GB. I just bought brand new SD card inserted to the tablet and the same problem still exist. Newer bios or OS when I comes up might manage it correctly. That is my opinion.

Ever tried to use your SD-Card with a smaller partition?
