flashed team sonics freeGS3 R5.. external card unmounts after reading as 123456789abc

so yesterday i flashed team sonics freeGS3 R5.. with twrp that i installed from the market. rom works great but now my external sandisk 64 card reads as 123456789abcdefg..ect and then it says it was removed unexpectedly. i think i read that twrp wasnt able to mount exsd in recovery. unless you install via terminal or the new version wasnt able to mount. i took the easy way out and installed twrp with the goomanger app.. and couldnt mount ex sd so i backed up and installed from my internal sd. anywho, has anyone else had problems with their sdcard not being able to mount? i read that other people where having this same issue with it reading as 123456789abcdefhi.. as of R3 but theirs worked so they werent worried about it. someone mention it might be due the sd boost? i never formatted the card or anything yet, it worked right out of the box in the stock rom.. im not sure if it wont mount because of the mounting issue in twrp or if the cards needs reformatted to something else.. anyone else experience this yet? tempted to reflash to see it it helps, i wiped eveything before the install, but i didnt reformat the system, which i normally do. any help or suggestions is greatly appreciated.. thanks

The 12345... is just a theme display problem. Try installing another theme, it should correctly say Mounting SD card...
Your 64 SDCard not mounting is because you're probably running a custom kernel that doesn't support exFat. Try formatting your SDcard as FAT32 or NTFS.

damaged SD?

can a sd card be damaged if its not removed while you gain root or cwm or flash a rom? i have a sandisk 64gb class 10 that use to work fine before i flashed my S3. After i flashed freeSG3 my sdcard wouldn't mount, keeps saying sd unexpectedly removed. it came preformatted as exFAT and worked fine on the stock tw rom. i stuck in my computer and it said it needed formatted so i reformatted as exFAT and copied a couple files to it. soooo.. im assuming it isn't damaged since it works in my computer. still no luck getting it work on my phone though. I tried my other sd's to see if it was the rom maybe but they work just fine, its only this card. im confused to why it isnt working now, but use to work but still works on my computer. ive only had it for a couple weeks and luckly i got it off of amazon so i can still return it. i've tried rebooting my S3, i even tried to mount in it my vibrant after i reformatted even though i know the vibrant doesnt suppport 64 gb.. it said damaged sdcard. ill give it a few more days of research before i send it in for a new one, im hoping i can get it to work again. my other option i was thinking about doing was to restore my phone back to stock to see it would work again. i dont really want to do that but i think i will for the hell of it before i try returning it.

Your SDCard is not damage, as I've mention in your other thread you are probably running a custom kernel that doesn't support exFat.
Either reformat your card as FAT32 or NTFS or flash back to stock kernel that does support exFat.
exFAT is a proprietary Microsoft product. They don't release licensing to open source software like Android. Apparently Samsung as some kind of licensing deal with Microsoft to use exFAT that's why the stock kernel will work with newer SDCARD formatted as exFAT.

I am going to piggy back on this thread and say that I have the "unexpectedly removed" bug
S3 running stock 4.0.4 - it works fine with a 2gb microsd, but I just bought a 32gb micro sdhc class 10 and it just won't read.
Tried exFAT, Fat32 - NTFS doesn't read on the card.
Suggestions?

I was using 32gb card earlier on Stock Rom-unrooted, rooted, RcMix and Xquisit roms without any issue. I know you would have tried but have to ask, did you try copying any data onto the card on a PC? May be some bad sectors are causing it to not recognize.
Can you tell me if CWM or TWRP recognize the card?
I don't have any issues with all my cards - 16gb, 32gb and 64gb ultra sdxc.

I've been putting off rooting it since I was content with the factory rom, but I guess I have no choice. I'll check CWM after I root it.
However, I can't copy any data onto it. Also, the phone recognizes the card but it keeps unmounting/remounting it.

how can I tell if CWM sees the card? Even after root, the phone sees the card, just can't copy anything to it.

Did anyone ever have a fix for the "unexpectedly removed".
Had the problem before. Reformatted sdcard and odin back to stock then flashed cm10 with no problems.
Recently went back to TWFrosty, and the problem exists again. Could it be from going back and forth between TW and Aosp?
My card is fairly new, about 2 mths? Maybe 3.. Weird error, it shows my external sd card blank, then all of the sudden if I leave it be all my files will show back up. Also it has went so far to ask me to reformat the card with my phone. I just avoid the answer, and eventually all my files come back. When I'm near a computer and it does this, I'm able to still see all of the files on the external sdcard on my PC, just not on my phone.
Thanks for all the help..

Sounds like you need to backup then reformat the card. You didn't say what kind/size it is or what format. That can help.

Well I've got same problem with my 32 SanDisk. Sometimes it's shown on my computer and my phone and tablet, but for the most part its just not showing at all. IdK what the hell is wrong with the thing. I have another one just like that one, and so far (knock on wood) no problems, so my hardware is ok........

For large (32/64GB) cards, if you're going to use an AOSP ROM, you have to format to FAT32 (or ext3/4). TW based roms will format to exFAT if you format it inside the phone. The drivers for exFAT aren't included in AOSP though.

[Q] 64GB SD card on CM10.1

I recently bought a 64GB SanDisk Ultra MicroSDXC card and right after I got it, I started to play around with it.
Like I knew, stock-CM10.1 doesn't support exFat, but I decided to just plug the card in and watch if the phone would suggest me to format it to compatible format. But nothing happened. So I went to Settings->Storage, and boom, force close.
I thought that maybe it was just impossible to format the card on android, so I formatted it on Windows (to fat32) but no luck. Still fc when I try to go to Storage Settings.
Next thing I tried was recovery-mode:
-fat32 in koush's touch recovery -> cannot mount external_sd
-exFat in PhilZ's "exFat compatible recovery" -> the same thing
Then I really began to think that this whole damn card wasn't supported at all. So I tried one more time.
Clean CM10.1 flash, a try with fat32 and exFat, and after that (and after 0 successful attemps) those both formats one at a time with RedPill kernel.
And nothing worked.
But one of my attempts was not very far from success: when I was on stock fresh CM10.1, I also tried Paragon's app for mounting NTFS-partition and it actually worked. The app itself confirmed that "partition was mounted and it was nearly 60GB large". But in settings and in file managers the card wasn't recognized.
The second odd thing that I noticed (actually because of a half-accident) was that if I formatted the card to fat32 BUT set the size of the partition to exactly 32GB the card was up and running perfectly.
So my questions are:
Is there someone who has 64GB sdcard working perfectly on AOSP rom? And if yes, what is your setup?
Is it some kind of bug in CM10.1/even in all AOSP-roms out there that cards over 32 gigs don't show up at all? And if it is just a bug can we expect it to be fixed in near future?
Or is Touchwiz based rom the only solution?
And if someone is asking what software I used to format the card on Windows I tried:
- fat32format
- HP USB Disk Storage Format Tool
- EASEUS Partition Master
- and of course stock Windows' format tool
And what formats I tried:
- fat32
- exFat
- NTFS
- ext4
Thanks in advance

I have the same sd card working on tw and aosp. I had to plug it into the computer and google formatting exfat 64 micro sd cards and youll find an app online. Download it to your comp and itll guide you through the rest. 10mins at max is all it should take. Hope it helps

Do you remember what aosp roms/kernels have you used while the card has been working as it should?
And do you have any clue what was that app you used to format your card?

I'll get on my computer tomorrow and tell you. But as far as ROMs and kernels, since I formatted my SD card to fat32 I use it for both tw and aosp roms from miui, to aokp, jellybam and all tw ROMs. Once your formatted properly it'll work for any ROM and kernel

Okay, good, thanks
EDIT:
Thank god, I got it working. When I downloaded and installed MiniTool Partition Wizard to my computer I noticed that somehow the whole partition of the sd card was changed to logical instead of primary. I simply formatted it to primary fat32 partition and now it works, finally.
And last but not least I have to say a big thank you.

sd card issues android 4.2+?

okay, i've tried and looked for a similar issue but so far i can't find anything related.
I have a sandisk microsd ultrahc card 16gb.
the card itself works extremely well, both in my device when using the stock / custom samsung based roms,
Didn't really notice this untill i tried out android 4.3, at wich i thought first could be a bug in the rom, the settings kept fc'ing the moment i opened up the storage part, and a com.android.media kept fc'ing the moment i attached the usb cable.
as i thought 4.3 was the culprit i flashed 4.2.2 wich also had similar issues up until the moment i removed the card from my device and restarted, everything worked smoothly afterwards.
I've tried using exfat / fat32 both with cluster of 4096 and 8192 and neither of those helped in any way. Turns out that both TWRP and CWM (yes i tried it in both) also can't seem to mount the sd-card.
Is there any workaround for this issue? or do i have to get myself another sd-card?

I think it's the ROMs man messing things up...i tried android 4.3 yesterday and my whole android directory changed like I had to go into a folder called 0/0/0/my android files. to reach my files etc couldn't mount from sdcard couldn't copy things across from pc...I just flashed back my original stock firmware and everything is good..... android 4.3 is pretty messed up..give it time to mature still very buggy

The messed up folder i should get used to thoug its because of the multiple user profiles things are getting a bit messy.
Its something they added in 4.2.2 i believe
Best way to do it is to flash the rom and afterwards copy back everything to the sdcard.
Didn't have any issues with another sd card i still had laying around but that thing even thoug class 4 doesn't get more than 1mbps transfer speed.

if the sdcard works on your pc with directly like by using an mmc adapter or sdcard to USB converter then your card is ok if it just didn't work on the phone it has to be a software issue our maybe the hardware mmc port is faulty??!
Sent from my GT-N7105 using Tapatalk 4

thats just it, the sd card works like a charm untill i upgrade to 4.2.2 or 4.3. however both recoveries can't mount the sd-card either.
its not one of those black ones that goes to class 10, but an ultra hdsc class 1 so might be something related to not being able to work properly with anything higher than class 10

nope....the class issue has nothing to do with software.....that's purely the job off the chip electronics/hardware.... I would say a combination of your recoveries and ROMs like I had the same issue once the custom recoveries maybe can't point to the location/ section of the memory card...try changing to different version of the recovery...maybe that could help but be sure the recovery is supported on your device...these are risky issues...so only do it at your own risk

i've tried several versions of CWM both touch and normal, also philz (yesterday but touch didn't work as it should so won't stick with that one) and TWRP but none of them could mount/find the external_sd, the only think properly working with that sd card is the stock samsung and custom roms based on stock.
(not particulary fond of TWRP, i like the layout and how it works, i just don't like the backups of that recovery, can't copy them to my computer, the extensions keep giving me an error and they are located on the phone's storage)
the sd card couldn't be found in my sensation xe neither i remembered just now after i stopped using the 4.0 stock rom and switched to custom roms, at the time i didn't really see a connection and thought my sd card just didn't want to work properly in my sensation anymore, But having the same issues, and using another sd-card in the phone worked again. Used the ultra sd card in my tabled and because i didn't use that one anymore and someone in my family needed a 16gb one for tomtom europe i gave my good one away )
gonna get myself a new sd-card this afternoon as the 8gb i had laying around isn't getting higher transfer speeds then 1mbps at most even if its a class 4. a shop nearby has a class 10, 16gb for 13 euro's so reckon thats not a bad deal, might even go for the class 10 32gb for 26 euro's if they have it in stock.

I have a 64gig card and had similar problems. With phils recovery it only works when formatted fat32. Think that exfat is not supported. With stock kernel it mounts exfat with any other kernel i tried it would only mount fat32. I think samsung kernel has support for exfat and others dont. So it might not be adroid related but kernel related.

weird thing is though, even when formatted to fat32 and not exfat, android 4.2 and 4.3 will not recognise my card, also the recoveries i only get an error when i want to mount my sd-card
my tablet which is running an aosp version of android 4.0 or 4.1 (can't quite remember) could handle the sd-card just fine, while both my phones have issues with it.
solved it by buying myself a new sd card, ^^ now i can at least safely backup to my external card instead of the internal memory.

[Q] 64 GB MicroSD card & OTG cable.....

Hi Fellow FLO owners!
Has anybody had any luck when using a 64 GB MicroSD card with their OTG cable?
I have already unlocked the bootloader and loaded a custom recovery and rooted my device, I then replaced my 32 GB microSD card with a new 64GB hooked up to my OTG cable via the USB port. For the life of me, I cannot read the newly formatted 64 GB MicroSD card? Has anyone tried this yet with a 64 GB sized card and was able to read their data? Was there something special I needed to do as well, download some other app or what have you?
If so, please tell me HOW you got that working or PM me.
Thanks!
Far-from-new-to-rooting and unlocked bootloaders, but, baffled nevertheless.

While I don't have a tablet in my hands yet to confirm or deny this theory, my guess is this:
A 64GB microSDXC card is going to come preformatted with exFAT; your stock Nexus 7 can't read exFAT partitions.
You can either reformat the card, or use a program to mount exFAT partitions (like this thing), or install a ROM that can read exFAT partitions (CyanogenMod 10.2 can do so; so can others, probably).

Ah, that sounds good, I shall give it a try and report back on my results! Thanks very much!!!

Oh, before I forget to mention it:
What recovery are you using? There's a very good chance it will be able to read / format the card for you.

Really? TWRP v 26.00
Oh well, I already reformatted it to NTFS now, the Paragon App didn't work. Currently, recopying files over now to the microSD card as we speak, will take about an hour.
Thanks again!
