Hey guys,
I got a new 64GB MicroSD Card. There are lots of issues with this card formatted in FAT32. (Files dissappearing, re-transfer of files causes disk usage to go up, but files still missing. Sometimes there are in put output issues.)
I've done a badblocks test on the SD Card and it show no issues. I tried formatting this card in ExFAT and everything looks like it works good. The only problem is, my Springboard Detects no SD Card if its in this format.
My question is, how do I get my Springboard to read ExFAT formatted SD Cards.
Keep in mind, that when an SD Card is inserted into the device, it gets auto-mounted to /media/sdcard2
/media/sdcard is used by the internal memory.
I checked the play store and it suggested Paragon and USB OTG
I've downloaded Paragon and it does seem to detect it.
I've also downloaded USB OTG, and it also doesn't detect it.
Help would be appreciated.
Cheers,
Zubin
AW: [Q] 64GB ExFat on Stock ICS + Root Springboard
Maybe this helps you or anybody:
Early this month Win7 got an update for Ralink based Wifi sticks, causing random errors during file transfers to both my androids with MyPhoneExplorer. Driver rollback helped.

Hmmm...not sure what this has to do with 64GB MicroSD Cards and the ExFAT filesystem on Android....but thanks?

Depends on HOW u transfer files to and from the pad(the card). I mostly use Wifi, and got OBEX errors and file skipping during bulk transfers.

Just wanted to report that the SanDisk 64GB Mobile Ultra MicroSDXC Class 6 Memory Card works fine in the Prime's micro SD slot.
I bought it from Amazon, which included a USB SD card reader for $149.99.
http://www.amazon.com/gp/product/B005V7WIA2/ref=oh_o03_s00_i00_details
The first hurdle I ran into is the fact that the card comes pre-formatted with the exFAT file system.
The Asus Transformer Prime does NOT support the exFAT file system.
At first the 16GB MKV file I copied to the card via the included card reader in Windows seemed to list and play the file in DicePlayer fine but seeking past 5 minutes would crash the player. When I copied more files to the card and explored the card via ES file explorer the file explorer listed all the directories as empty, even though when I put the card back into the card reader and read the data through Windows everything appeared and read OK.
However The Prime will read and write fine to an NTFS formatted card. NTFS format is preferable to FAT32 since you can't copy files to a FAT32 partition larger than 4GB. As I have several movie files much bigger than 4GB FAT32 would be unsuitable for my (and most people buying a card of this size) needs.
To format your card as NTFS in Windows:
1.) Put the card into the included full size SD card adapter
2.) Insert the card in a USB reader (one was included with my purchase from Amazon)
3.) Connect the USB reader into the computer and wait for windows to assign it a drive letter.
4.) Open up a command prompt (start menu->"Command Prompt")
5.) Type the following command (replace the x with the drive letter assigned to your SDXC card).
Code:
format /FS:NTFS x:
After I formatted the card as NTFS and copied my data to it everything read and played fine.
Asus licensed drivers from Tuxera, (link), but wasn't clear about exFat being included or not.
The manual does specifically call out NTFS ...
Wonder if exFat might be supported in ICS?
FWIW, exFat is potentially a bit more efficient for flash memory, but at least NTFS is supported.
Cheers, wasn't relishing converting my Fat32-formatted 64GB card to something else to test this out (BTW, Fat32 will take files up to 4GB, not two, but still restricting for HD video).

Thanks, was noting the FAT32 file limitation from memory, corrected the OP.
Looks like the Amazon resellers raised their price to $199.99. Best price I can find now is here ($161.36 with tax/shipping) :

Isn't there a convert tool to convert FAT to NTFS? Don't know if it works for FAT32 or not, but ...
Ah yes, here it is:
Code:
C:\Users\Me>convert /?
Converts a FAT volume to NTFS.
CONVERT volume /FS:NTFS [/V] [/CvtArea:filename] [/NoSecurity] [/X]
volume Specifies the drive letter (followed by a colon), mount point, or volume name.
/FS:NTFS Specifies that the volume will be converted to NTFS.
/V Specifies that Convert will be run in verbose mode.
/CvtArea:filename Specifies a contiguous file in the root directory that will be the place holder for NTFS system files.
/NoSecurity Specifies that the security settings on the converted files and directories allow access by all users.
/X Forces the volume to dismount first if necessary. All open handles to the volume will not be valid.
C:\Users\Me>
I could be wrong but I think convert.exe only works on FAT16 or FAT32, I don't think it works on exFAT. Regardless you're probably better off with a clean format to make sure everything is nice and clean with no unreadable (bad) portions.
I wonder how it would perform (if at all) if you formatted the card as ext4 instead of ntfs.

Does the card stick out of the side at all? I hear some cards are longer than others and create an annoying bump on the side of the tablet.

It's raised out about the exact same amount the volume rocker extrudes from the Prime.

Didn't test with ext4, ext4 is a much harder partition format to work with in Windows.

You convert fat32 to ntfs with the windows command line " convert" . Did the same with my 32gb sd card
Anyone tried a SDXC in the SD slot of the dock?

FWIW I got a wild hair and formatted my new micro sd card with exFAT and I am able to read and write using my Prime with ICS
Edit: I also did some tests and it seems write speeds are increased a bit with exFAT over NTFS
I'd love to see some crystaldiskmark numbers from your card!
P.S. also really happy to hear that exFat is working via ICS ... it should be better than ntfs for those that want >4gb files.
can you test out how fast it works? Writing and Reading speed both.
Does anybody here have ubuntu? It supports formatting in all the above file systems, as well as the norm browsing/filetransfer/ and all the such.
I've bought the card a week ago and it worked fine on my Prime without ICS (only got ICS last night; German SKU). Write rates using the supplied SD card adapter on my PC were around 7.5 MB/s.
No need to convert unless you want to use it with a Linux box.

Mine also worked with exFat until I put a bunch of data on it. Try copying a 8GB+ mkv to it and see if you can seek/play the entire file. My experience in Honeycomb was that it failed to read the entire file and if I copied more data to the exFAT formatted card then my files started disappearing from any file explorer run on the Prime (though still visible in Windows when connected to a dedicated USB card reader). This was my experience in Honeycomb, haven't re-tested with ICS since everything works great when formatted as NTFS.

OH my god are you saying you can read and write all 64 gigs on the card? No issues at all? Is there any disadvantage over using a 32 gig card?
Hello there,
I just bought a 32GB Class 10 Samsung MicroSD card.
After inserting it, I made sure the phone sees it, and the computer sees it.
So I started transfering files to it...
Every time I try to transfer files to it, the cards sort of unmount, the computer stops seeing the External/Internal storage drivers info (0/0 KB and no files).
I realized I might be needing to format it, so I went to recovery and formatted the external card. Still no good...
If I don't try to transfer files, the internal sd card still works fine.
Am I formatting it wrong? or some other issue? Did I buy a faulty card?
Thanks!
P.S. Some info incase needed:
Using Galaxy S2 obviously, Resurrection Remix ICS 4.04
My PC is running XP SP3
[edit]
Added some pictures to demonstrate what I mean.

If unsure about the quality of your SD card google for h2testw. It is a Windows test software you can use to test your SD card.
Tried formatting it... still no good.
And h2test tries to copy a file repeatedly and after some time it also gets stuck like I do manually...
I was running into the exact same issue as you with an SD card awhile back. Tried many, if not all of the suggestions listed here. Sometimes, the cards just die on you, especially at the most inopportune times...

Open CMD
Type format [letter_of_external_card]: /x
ex.
format E: /x
and wait.
Then format again (through Windows Explorer) with this settings:
FAT32
default allocation size
fast formatting checked
and share the results.

Failure of h2test is normally due to defective hardware.
For SD cards I do not really know but when it comes to USB sticks there are many around that are just cheap crap. You could for instance buy a 8GB stick that will happily accept 8GB of data but only store 4-6GB!. This is where h2test comes into play: it will not only write but also read and therefore check if the data written was really stored in the flash.

Class 10? That card might be just too fast for your hardware.
I'm using Sandisk 32GB Class 4 and never had any problems.
I have tried some Class 6 and Class 8 cards with very various results.
Only class 8 card I found correctly working in my device was Memorex, but it was only 4GB.
So I gave up on fast cards...
its fake or corrupt,did you buy the samsung off a retailer , you always test flash with h2testw before you use it, speed is not the issue,i got a class 10 32gb i had many 16,256,4gb fakes, only 3.7 gb usable droped down to 1kb write then windows couldnt read the storage so you reformat again.
So I formatted my 64gb sd card to ntfs and using paragon android can use the ntfs sd card. My issue is why doesn't it auto-mount when turning off mass storage? I have to mount it manually to "automatic" mode to /mnt/sdcard. So it's a pain getting mass storage to show the 64gb drive and when it does show up within 5 minutes of copying files the drive disappears from windows and fails to work. I have to set the phone to charge only, then mount paragon. Then go mass storage and it will then show up again only to fail shortly during writing.
On top of all that when I browse to view the files, they don't exist in the sdcard like the files and folders I clearly copied aren't showing up. However some folders and files show up. I don't get why mx video player doesn't see any video files in /mnt/sdcard/media/movies when I clearly copied 2 files into it and they don't show up at all...
It's a Sandisk class 10 uhs 1 64gb stick
format it as fat32
problem solved.
you should need a reason to have it as ntfs what files are you trying to put on that are over 4gb because that would be the only reason why you would.

Yeah my Galaxy note 2 can handle all hd formats like .mkv so I wanna put my 8gb .mkv's on there to watch in flawless uncompressed quality.
What's up with Paragon? Or what u know... Like it stops working after 5 minutes of transferring files
No idea but android doesn't play nicely with ntfs. Use exfat.

Does exfat work with windows? I need to be able use usb mass storage but I guess i could just use wifi transfer it's slow but better than nothing...
exfat support 4GB+ file limit right?
What's up with paragon? ppl have said it works good but it's clear to me that's it's extremely problematic.
Exfat came with windows 7 and supports 4gb plus.
I haven't tried paragon, it also could be a kernel issue.
Sent from Moto Atrix 4g on Neutrino 2.91
Not sure Android supports exFAT. FAT32 is your best and safest bet, even though it has limitations.
new kernel didn't fix the issue so i guess i have to use fat32... i dont see why paragon is messing up
what about usb otg?
*UPDATE*
I fixed the problem by plugging the usb cable directly into the usb port rather than through the 6' usb extension.
So NTFS is working flawlessly and I already copied over a 4.5GB .mp4 in 1080p and it works perfectly
I have rooted my z2 and the sd card is constantly mounting then unmounting. This is getting really annoying as when trying to watch movies or listen to music it just stops halfway through because it removes the card. has anyone else had this issue? Also i am unable to download the latest android update all it says is unable to verify.
Well if you unlocked your bootloader to root, then you won't be able to update your device through official ways anymore.
I have no idea about your SD card, try backing up its data on your pc and then reformat the card?
Yeah probably have to wait untill some custom roms come out
reformated the card exfat, however everytime trying to copy to the z2 it will copy for a while then it will disconnect meaning i have to start all over again. I dont think i have came across a tablet that is so bad at handling an sd card truly awfull. I hate to think how bad shooting video will be with the card continously mounting then unmounting. Ans no its not an issue with the card because it works perfectly in my pc and galaxy note 10.1
Anyone ??

What if you reformat as fat32 with 4096 bytes cluster size, instead of exfat ?
Have you tried running an error check on the card ?

not possible to format fat32 in windows no more by default. And the issue is any videos etc on the card will be limited to 4gb file size. The Z2
natively uses exfat so why would it keep disconnecting? when i pop the card into my galaxy note 10.1 it doesnt do it so it is clearly an issue with the tablet, but will give it a try
with fat 32

Then I suppose your tablet has a faulty card reader unit. I'm sure you can get it replaced or repaired without any hassle.
I am on my second, stock romantic same issue on both unless it's in its case
tried fat32 and the same thing happens what an utter load of rubbish cant even handle a 64gig card. btw this i my second z2 same thng happened on the first before and after root. Thought i would try sony as never tried their tablet devices before and was impressed by the specs on paper, what a major mistake the worst tablet ive ever used. Im gonna return it and stick with samsung like i always have and ugrade to the new note 2014 edition. Sony Fail!
Well if it's the second one in a row with this issues, I think there must be something you're doing wrong? Or maybe your SD card specs just aren't supported? What are the full specs of your SD card? And is it one of those extreme high-speed cards for (video) cameras? And aside from reformatting it on a pc, did you ever try reformatting it on the tablet itself? This is an issue I've not read of about this tablet before so it kind of puzzles me that you already had it replaced once and immediately have the same issue again.
its a sandisk ultra micro sd card i have formated both on the pc and the tab. Also i formated it as fat32 but after a while being in the tablet it seems to convert it to exfat again. i have also tried different cluster sizes. I have tested this card in my samsung s3 samsung galaxy note 10.1 pc my laptop and have no problems at all so im at a loss

Only idea I have left is for you to try other micro sd cards and see if they cause the same issue.
I think it might be to to with the number of files the tab can handle if i have nothing on the card it doesnt seem to do it but the more files are added it starts to keep unmounting the card and constant rescanning. i have about 3000 mp3s on the card. Its not like its cheap memory its a sandisk 64gb class 10.

I am using a 64gb and have heard 128gb work too. I use a fat 32 partition and link2sd and use external sd as main storage.
I too am using 64GB -- formatted to FAT32. If I recall, my card was pre-formatted with 2 partitions which the phone will not recognise. If you format it to NTFS, TWRP might not recognise it in recovery mode. Windows will not format such a large drive as FAT32, so you will have to use another tool -- e.g. MiniTool.
The caveat is avoid using a (cheap) USB card reader. I've corrupted the card before when transferring too much data to the card. Newer readers built into your laptop or using the USB cable directly to the phone seem okay.

^^ Same as those guys, I also am using a 64gb card. No issues! Though surprisingly it made my Xperia bug out, lol
Just be sure you get something beyond first gen (40,MBS) cards. I have had 0 issues with anything up to 64gb I now have two 128gb cards that both work but get corrupted and require a format every time I attempt to transfer 10 + Gigs of information at a time.
