Hi!
I've found this results of tests of different SD cards and Internal Storage with EXT4.
But what are this test results with default FAT32/ext3?
As I understand, there is no matter to install Uruk on Internal drive or on good SD card (Internal even often better). Is it really so?
And what is means by "metadata"?
BR. Philipp.
good question, I don't know what the metadata means. All I know from testing is that the internal sd is quite fast indeed. Copying large files to the internal 8G, I get speed close to 10MB/s, and reading speed is 12MB/s, that is close to a 10x card, and this is all on FAT32.
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?
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

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.
I bought a Sony SR32UZ 32GB SDHC/SDXC Class10 UHS-I microSD and after formating to adoptable storage and transfering 10GB data to it from my PC(Titanium Backup, songs, documents, few apk) it becomes damaged after a reboot. Previously I had a Kingston 32GB class 10 and worked fine but I forget to format back to removable sd card and after ROM change it become permanently damaged.
The Sony card is damaged but I can format it to try again but it always become damaged after a reboot both with CM13, Resurrection Remix-M and Resurrection Remix-Nougat. Is this a ROM bug or what?:crying:
The old 32GB isn't damaged. It's encrypted and, thus, inaccessible.
Try to format it in recovery or on a PC.
As for the new one, try formating it again.
I tried a hundred times and it looks like Sony card is only usable on custom ROMs with FAT32. I even tried Link2SD method with FAT32 and second partition with ext4 and ext4 got damaged after reboot.
Try to use minitool to allocate all the space to one partition as fat32 or exfat.
I did that. FAT32 works, exfat is damaged after reboot. But you can't install apps on FAT32.
Perhaps, a problem with encryption?
Hard to say though.
Adaptive storage and data encryption were known to have bugs in the past. As for data encryption, I don't think it has been fixed.
That's why I don't use them.
I'm now using Droidmaster's tweaked 5.0.2 ROM and Link2SD with Sony Microsd. 8GB ext4 partition and 21GB FAT32. Did several reboot and Link2SD is still working. Also my Kingston sd card is dead because nothing can format it, tried with everything, EASEUS, Minitool, Gparted, Windows. Even in phone with a paid and a free partitioning app. I think it is safe to say it is dead. Maybe if I get further problems with sd card I will order a Meizu M5 32GB ROM and 3GB RAM because it is very cheap. I love my G2 mini but these sd card things are frustrating also sometimes would be great if it had 2GB RAM.
I just realise that the tablet doesn't support exfat formated sd card. I tried to connect the card via the port (phantom 4 footage) and say it is not support exfat /ntfs format. The strange thing is that my note 10 plus support exfat and open the files. Unacceptable for this device. I hope there will be a fix soon. Does anybody knows any other method to open this kind of formats?
If the card is larger than 32 GB, then it's microSDXC. These cards come from the factory already formatted as exFAT because that's what the SD Association's specification requires. microSDXC has been available since 2009; surely the S7/S7+ support it. You can learn more than you ever wanted to know about SD cards from the excellent Wikipedia article: https://en.wikipedia.org/wiki/SD_card.
I'd suggest you reformat your card, but not in your tablet. Instead, use the SD Association's formatting utility for Windows or Mac: https://www.sdcard.org/downloads/formatter/. It configures the correct block size specific to your card.
My 512GB exFat card works just fine in my Tab S7+/LTE. I'd do like Steve suggests and reformat the card - sounds like either the block size is off or it isn't either of the formats you mention. Also AFAIK, NTFS isn't a supported option nor is HPFS.
