Warnings with SD cards for A2

So I recently ordered a Sandisk Class 4 16 gb sd card for my Atrix 2. I wanted to be able to keep a backup of a ROM at all times while having 500 songs on my phone..but 2 gb just didnt cut it.
So i tried to connect the card with my phones USB cable while having it in the device, but it just wasnt showing up on the computer. I had to end up using a card reader.
It still works...just something to keep in mind while buying SD cards.

In order to view files on your sdcard on your computer, you have to select the "USB Mass Storage" option.

Did you format the sdcard IN THE PHONE prior to trying to view the files via your computer?

thats probably it. I had this happen off and on until I let android format it. my recomendation would be to put it in your computer and format it as fat32 then put it in the phone and have it format it

Thanks a lot ill try that

Although problems do not seem to be prevalent with the slower class cards, it might be a good idea to follow Patriot's advice regarding formatting. The suggestion was posted by Patriot in response to a review of a 32GB class 10 microSDHC.
Patriot acknowledged a problem with hemorrhoid OS and 32GB class 10 cards and suggested a temporary fix of performing a full format on a Windows PC with a 32kb allocation size, obviously FAT32 since stock hemorrhoid does not recognize NFTS.
The reply can be found in this review although the specific page will change if more reviews are added.

Be patient... they'll likely come sooner or later.

I got a 16gb class 4 sandisk and I am formatting it in my computer using following method:
I inserted the memory card in my E71 and connected it to my computer in mass storage mode. Then I started formatting using fat32, 32kb through my computer. But it is taking ages. Since last 2 hours, only 35% is completed. My questions:
1) Can i stop the format in between ? Or will it lead to certain faults?
2) Is the format this slow? Or should I try formatting it by putting it in adaptor and putting the adaptor in laptop slot and then format?

I'm using a Kingston 32GB Class 4 card, which is actually in my SGS3 now from my A2, and I have never seen anything to complain about with it. I still hit high benchmark scores as noted with my A2 as well as my SGS3, thinking though that I may try a higher rated class sdcard for the SGS3, since it doesn't seem to have the issues that the A2 has seen. But, a little more digging around has to be done before I make that kind of jump! (Better safe than sorry!) But, yes, the Class 10 cards will -eventually- give you grief if you try to use one with the A2. Not sure the 'scientifically-proven' answer to give here, just know that from everything I have seen, which has been substantial enough for me to believe that...

You should try a re-formatting of the sdcard, as you likely have some corrupted app data/other data that is causing the rebooting. A Class 4 card should give you no problems like this, unless you have some issues like I just mentioned.
And if you're trying to restore app data from, say, Titamium Backup, I recommend you do not do this. Just try a fresh format of the card, and do not restore data to it. Run your phone afterward for a good while to test. If your phone continues to reboot after you have tried this, changes are that you can rule out the possibility of the cause being due to the sdcard, and we can explore other possible known culprits...

I just put an 8gb class 4 SD card in my phone. I formatted it via the phone twice and rebooted. My camera saves pictures and videos that say they can't be opened when I try to go play them. And Doggcatcher has the majority of my podcast downloads failing. This has persisted after a couple reformats. Thoughts?

[Q] My phone identifies the SD card and data on it, but few things are accessible

Alright, first let me start by saying that I hope this is in the right area and i'm sorry because i'm sure this question has been asked to death.
I have a Galaxy S 3 Running stock with android 4.0.4 (Not rooted)
I also have a SanDisk Ultra 64GB SDXC class 10 MicroSD card (Formatted to FAT32)
I have had the phone a month and for probably the first week I was using the card in the ExFAT file format...Then random card identification problems started to pop up. So I scoured the web for a short time and found that the issue could be solved by reformatting the MicroSD to FAT32 at the expense of not being able to have single files larger than 4GB. Everything worked for a good week, then suddenly the phone didnt know I had music on it anymore, my player stopped and i confusedly navigated through songs that weren't there. I removed the card and reinserted and the files worked again.
Well today the phone is doing the same weirdness again, it is identifying that there is in fact a 64GB MicroSD and the amount of data is correct. It is also allowing me to navigate to the files in ASTRO, even my PC still detects and allows me to Add/Delete files from the MicroSD...BUT my phone will NOT use it. For example, if I go to camera and want to take a picture with the destination being the MicroSD, the phone says "What MicroSD?", also my media gallery is empty (Save for the files stored in the internal storage) and my music player is empty as well.
Anyway, I didn't know what course of action I should take. Does it sound like one or both of these items needs to be returned/reformatted/smashed with a hammer?

I am not sure if the sgs3 supports 64gb cards, i suggest you first try with a 32gb card to see if it is a card reader problem or a mmc problem

If that's the case why does it state on all the North American Cellular phone websites that the phone supports "Up to 64GB MicroSD"? Seems crazy that such a large feature could be so buggy.

The GSIII (international and US) variants do support 64 gb micro sd cards. It's advertised on the box.
It sounds like your sd card is failing you. Definitely backup all your data to a computer and think about replacing this micro sd card via manufacturer warranty.

[Q] 64GB SDcard format question

I ordered a new Sandisk 64GB SDcard but after reading many threads on the topic here, I have a question about the format. From what I've read, in order to have the card recognized by CWM and other custom recoveries, it needs to be in Fat32 format rather than exFAT. Many people have suggested that you can use a Windows based 3rd party software to properly format the card, but I don't have a SDcard reader on my PC so I'm not sure what my options are at this point. I tried searching the forums about posts from people in a similar situation (i.e no card reader on PC) but was unable to find anything. Any suggestions or ideas on what I can do to retain the full 64gb capacity and still be compatible with CWM without having access to a SDcard reader? Thanks very much.
Link to card: http://www.newegg.com/Product/Product.aspx?Item=N82E16820171582

Will need to find a PC to format it. It comes ExFat and not only recoveries won't see it but roms/kernels may not see it either. The program is guiformat. Can Google and find it easily. The site is little confusing. Click on the picture of the app and it will give you the download.

Thanks very much for the response. I was afraid that would be the case. I honestly don't know anyone who has access to a SDcard reader, so I might have to just end up returning it to Newegg for a 32gb version instead. Thanks again, I sincerely appreciate the info.

I actually dug around in my basement and found my old PC tower that has a built in 8 in 1 card reader that supports SDcards. If I can find a way to extract it from the old tower and hook it up to my new one, I may yet find a way. Thanks again for the continued help.

Yea. Only difference between 32 and 64 is don't need a special program for 32. Windows can do it natively. Good luck.

I realize this question may sound ridiculous, but I figured there was no harm in asking.
Is there any chance I could stick the 64gb card in my old Droid X, connect it to my PC, and then use the program you suggested to format it to FAT32? I guess I was hoping the phone could act like a SDcard reader of sorts for my PC. Thanks again.

Won't work from phone but go to radio shack and get cheapest one of these you can find. May be able to get with 1GB card. Take pic and show them what you want. Sorry I been busy and didn't think about it. Good call Droid. $12 max.

So I purchased a SDcard reader, hooked it up to my PC, and formatted it with the guiformat program that was recommended earlier in the thread. I set the allocation size to 65536 and left the Quick Format option checked. However, after it finished, both Windows and the S3 only show it as a 32gb card (approximately 27 GB total storage space). Is there another formatting program for Windows or any other ideas you could recommend so I can get the correct storage size (64gb)? Thanks again.

I tried using a few different programs to format the card to FAT32 but every time it still showed up as a 32gb card. I ordered it directly from Newegg so I don't think the authenticity is an issue, but I have no idea what could've caused this to happen. Regardless, I sincerely appreciate the help I got from the folks in this thread and via PM. Thanks again for your time and effort.

There's another thread detailing all the issues with exfat 64gb cards here:
http://forum.xda-developers.com/showthread.php?t=1698672
I encountered the same "hiccup" as you pertaining to the 32 gb issue.
I ended up using a program called EaseUS Partition Master to finally get all back to normal. I wiped my sdxc partition, it did come back with some message that something didn't complete ???, but then I formatted as fat 32, primary partition, and got the entire 64gb back and so far... ( fingers crossed ),.. all seems to be working well.
With the card formatted as exfat, as soon as I got around 8 gb of music, photos, etc.. the card simply would loose its' file structure and just start acting weird. All files would still show up if I pulled the card and put in an sdxc reader on the PC... but my Galaxy S3 never would recover them properly.
This has got to be some kind of "bug" in the phone as you'll see in the other thread this problem is quite common.
For what it's worth.. I seemed to have much better luck transferring large chunks of data with the card in the reader opposed to hooked up while in the phone. ( speeds kept dropping via the phone cable )
Good luck!

Thanks for the info. I actually tried the EaseUS Partition program you referred to, but it still remained at 32gb. I ended up returning the card to Newegg and will just get a 32gb to replace it as I'd rather not have to repeat this process. Thanks again for the useful info. I sincerely appreciate it.

Sure... I vaguely remember I had to try to format as NTFS first for some reason before I got it to properly format with entire 64gb fat 32. I spent countless hours trying to work out all the bugs with this card and exfat. Samsung states the Galaxy S3 phone is compatible with it... but there is definitely an issue with file structure once you start loading it up.

Quick update:
I ended up returning my Sandisk 64GB and replaced it with a G.Skill 32GB (Class 10) that was on sale for $22 from Newegg. Surprisingly, it came already formatted as FAT32 so I didn't have to mess around with it to get it working with CWM and custom kernels. Seems to be working great so far, and is plenty fast, so I'm pretty happy with the end result. I guess it might have been nice to have an extra ~30GB, but I mainly stream all my music/video anyways, so I'll have a tough time even filling up this new card.
Thanks again to everyone who gave me their advice and input on trying to get my first SDcard formatted correctly. Even though I wasn't ultimately successful, I sincerely appreciate everyone's time & effort.

SDHC only supports up to 32GB I am going to answer Samaung support and ask them how they support 64GB when SDHC only supports 32GB.
The Secure Digital eXtended Capacity (SDXC) format supports cards up to 2 TB (2048 GB), compared to a limit of 32 GB for SDHC cards in the SD 2.0 specification

I assure you my 64 gig sandisk sdxc card works just fine in the S3.
I kinda missed all the issues with read problems, because when I got it was before I had an S3.
When I got it, I opened the package, put the card right into my T-Mobile MyTouch 4G Slide phone, formatted the card in settings, and have been able to use it in that and the S3 fine since.
Maybe try formatting the card in another/older phone and see what happens? I was running gingerbread on it at the time.

i really depends on which file system is compatible with yer kernel. SDXC by default uses exFAT which won't read with a stock kernel. reformatting the card in your phone will format using the FAT32 File system. FAT32 is a lot more compatible but it has it's limitations like cant copy files bigger than 4 gigs.

FAT32 works and it doesn't. When I play videos it will randomly cause the phone to hang, then reboot. Not at any consistant time into the video either. But the data stays intact.

I actually came to this forum to ask about close to the same question. I'm using the first card that pops up when searching "64 gb micro sd" on amazon, and frequently (while watching videos) the phone will crash, followed by 2 vibrations, and then it boots up again.
Do you also have problems with music saved on the card? On occasion, my phone will skip tracks and will only play a few of the songs. This only happens over bluetooth (so far), and manually clicking one of the songs on my phone causes the rest to work again.
I've also been having issues with the card in general. Sometimes mine will say it's corrupt at the top, but a simple reboot or dismount fixes it.
Please let me know if you find out anything.

The only official thing that I have from Samsung is that they support 64GB micro SD cards but they do not support the microSDXC, only the SDHC. 64GB is only available in SDXC. So I think the safest way is to go 32GB SDHC. Although from reading some prople have the 64GB SDXC working but many have problems with them, including myself. Another confusion point, San Disk says it will work. I have some older flavor of 16GB card in mine now and it has been very stable.
Whiskey Tanko Foxtrot

Thinking;
Is it possible to format the 64GB SDXC with multiple partitions? Create (2) 32GB partitions formatted FAT32 each.

I used a 64 gb micro sd sdxc out of the box on CleanRom. I formatted it on accident when trying to wipe everything preparing for a different rom. Now the sd card only reads 27.4 gb. I have seen countless threads on here and google but i am not seeing a solution. Any ideas?

does the de-odexed and odexed type of rom have anything to do with if the phone recognizes exfat or fat32 sd cards?

Uhh, not necessarily. It's primarily a kernel related issue. If you're using a TW rom that comes with the official OTA kernel then you'll have "no" problems with exFat. Synergy is one TW rom that I'm aware of which comes with exFat support courtesy of a custom kernel by a dev named Ziggy. Most custom kernels don't have exFat support. You'll have better results if your TW rom includes the stock OTA kernel, the same can't be said if it comes with a custom kernel. But exFat support is not based on whether the rom is deodexed or odexed.

Uhh, not necessarily. It's primarily a kernel related issue. If you're using a TW rom that comes with the official OTA kernel then you'll have "no" problems with exFat. Synergy is one TW rom that I'm aware of which comes with exFat support courtesy of a custom kernel by a dev named Ziggy. Most custom kernels don't have exFat support. You'll have better results if your TW rom includes the stock OTA kernel, the same can't be said if it comes with a custom kernel. But exFat support is not based on whether the rom is deodexed or odexed.

That makes things a lot clearer. Thanks for the response.

I use a sandisk 64 sdxc every day with no issues. I used a windows program called EaseUS partition master to format it and its all good. Pictures, music, movies, flawless. On touchwiz and aokp ROMs. Primarily stick with leankernel.

[Q] SD card just died

I've had a 32 gig micro SD in my phone for a while now. I recently took my Siii out of my pocket only to find that it says the SD is unmounted. Odd, but not unheard of in the world of custom roms (paranoidkangdroid 2.something, rather recent though, 4.2.2 JB) So i do the sensible thing: Run into the storage menu, and lo and behold, its not registering. I pop it out and in, not registering. I reboot, and the damn thing still isn't registering. Then I take an old 2 GB micro SD and try it. This one worked just fine. 32 gig however does not. I move to my PC. Pop it in a micro to regular SD adapter, and the computer doesn't mount it. It does mount every other microSD of mine though. So can anyone tell me what the hell happened, and how I can recover my stuff?

Actually you can't, your sd card is corrupted and it's known to happen with this device that's why I always keep a weekly backup on my computer with everything. Especially the ones ordered from amazon the high capacity ones as far as I've seen.

Well ****. I guess you're right, it just showed as unsupported file format.

And now its not. This is frustrating. I don't want to spend money on a new card dammit.

Try booting a linux live cd and see if you can save anything, thats how I recover deleted tomtom maps in the past.

Is the SD card damaged or can it just be reformatted with a card reader on a PC (fat I am assuming)?
I was about to start using an SD card to backup the internal storage. It doesn't sound like this is the best option and backing it to my PC would be better.

My set up to start was cleanrom 6.2 with envy kernel running fine for a week. I had my sd card disappear today twice. PNY class 10 32gb less than 2 weeks old from best buy. Popped it in my pc and it was recognized no problem. So I transferred my data, formatted in fat 32 popped it in phone, no problem. Transferred data back and was Ok for a few hours. Swapped my battery for a freshly charged one and upon boot, phone said the card was damaged, to reformat it. So, I pulled it out and popped it in my pc. Pc said card was damaged. I opened a command prompt and ran a chkdsk /f and it fixed an issue with the file system. I then proceeded to restore my cleanrom 6.2 backup. So far so good. I am thinking it had to do with an app, but I can't be sure. Upon googling this, it seems that some people have had an issue with external sd cards with this phone.

I'm not sure exactly what brand or model you have for your SD card or when you purchase it. However if its a SanDisk and it was purchased before December 2012 there's a chance that it was part of a bad batch. I had the exact same problem with mine I have a UHs 1 32 gig SanDisk. I read somewhere on the internet that there is a known problem with SD cards from that company built before December. When I spoke with SanDisk they confirm that and said the newer batches have been corrected. Long story short if you're using an ultra high speed or for that matter any card by SanDisk call up there customer service explain to them the problem and they will send you a brand new one. The entire process took about a week for me.

Please hit the "Thanks" button if I helped you!

Did you try my suggestion? Ive recovered numerous files using a linux live cd and/or a mac. Try putting the card in a network printer or mem card reader if linux and mac os isnt possible. Ive recovered my files, including those from a 16gb micro sd card, using those methods in the past.

Okay, so it works
Alright alright, i didn't expect this to get many responses. Anyway, it now works. It appeared to be fried, my mac, PC, ubuntu machine, and OG droid wouldn't even recognize that a card was inserted. Nor would my GS3. My solution? after turning it on and off a few times, I just left the card in it and set it aside for an hour. Lo and behold, it now works. The SD now works. It was fried, and is now unfried. I don't know how, I just guess I am lucky. Or aliens. Either way, I am happy. Not gonna jeep anything more than music on it though... Ah well, thanks for the help XDA!

If I were you, I'd back up everything on that card to my pc, and exchange it if under warranty. If not, chuck it, and purchase another card.
Not worth taking the risk again.
Consider yourself lucky so far

The problem could be a sandisk SD card:
(Outside link) crave.cnet.co.uk/mobiles/samsung-galaxy-s3-fault-is-caused-by-sandisk-memory-cards-50010684/
I read about the SD problems after just getting the S3.. decided to get a different brand card from the store.
