Are there any advantages to formating the SD card to FAT32, other than being able to flash a ROM from it? I don't know if I'll ever flash a ROM that way, but I'm about ready to copy a bunch of tunes and install some GPS maps to my 6 GB SanDisk SDHC, and wonder if there would be any advantage(s).

I could be wrong but I thought it was to make the partitions larger then 2 gig. Just like when Windows 95 was in the transition from going from FAT16 to FAT32. FAT16 can see only 2 gig FAT32 can see up to 32gig. I remember having an 8 gig hard drive that had 4 partitions of 2 gig each with FAT16. FAT32 uses smaller clusters (4 KB for memory up to 8 GB), resulting in 10 to 15 percent more efficient use of space. That is all I am aware of. Maybe someone else has some insight.
So does that mean that my 6GB SDHC is already FAT32? If I put it in a card reader on my PC, will properties tell me what it is?

If you are seeing 6 gig on the memory card as one partition then yes it should be in FAT32. I think the PC properties will just say FAT.
my 8 gb was fat32 by default. I think all SDHC cards are fat32. I think i seen an option to format to NTFS. Any benefit over that?

My 2 gig was FAT in the PC, got a 8 gig last weekend and it came FAT32 from Sandisk, as the post above is correct FAT (16) is limited to 2.1 gigs per partition because the File Allocation Table is able to handle only that, but FAT 32 is needed for more than that, and your PC will show that under Properties for the device.

Don't bother as I bet it would not even read or write it, and there would be no advantage anyway as mostly NTFS (Windows NT Filesystem) is mostly for file privilage and security anyway, no speed or capacity help at all.
Pros
1 - Fat32 is compatible with just about any device you would put it in
2 - Uses space more efficiently than Fat
3 - Bootloader can read it
Cons
1 - Has a limit of 2GB filesize.
2 - Not as efficient as NTFS in using space. Will waste space proportional to number of files saved.
Very short list...I'm sure there are some more in both categories.
I keep it Fat32 simply because if I need to trasfer a file from one computer to another (I have an 8GB card) I don't have to worry about compatability issues.
And as someone else said I'm pretty sure NTFS isn't even readable by any phone.

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.

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.

I was able to use Easyus 9.1.1 and it formatted fine

the card is seen fine with its correct size.
I wish hboot and the OS understood sdcard as ext2/3/4

Welcome to windows. There is a reason why but honestly I forget what it was. Windows has a size limit of 32Gb...hence it being called fat 32
Ironically the format tool built into Mac osx will format fat 32 to any size drive. I had a 250GB hard drive completely formatted fat 32 at one point. Long story.

Not sure I understand the issue. If for some reason your computer has trouble formatting it, just put it in your phone and it does it for you.
As another user said, windows will not format any disk space larger than 40ish GB in any FAT (12,16,32) format. FAT is pretty much useless nowadays anyway. I format even my smallest flash drives 1-2gb in ntfs. Much less problems. Fat just can't handle larger partitions. It was designed when whole programs fit on a 5in floppy and hdd were less than 5gb to take up very little space. Ntfs is faster and more efficient now.

Yes but the Android OS and bootloader
dumbly insist that the external card
be Fat32 instead of a Linux style EXTx
filesystem without those limitations.
Especially now that the phone can fake
out windows into treating any
filesystem as if it was a windows compatible file system.
I just don't understand why that is still
so?

On my 32gb card when I put it in my card reader it said it was corrupt and windows tried to fix it. I do recall giving it permission to do so, and it was fine when i took it out of the phone. So now everything is in .chk
I have recovered a few items from the chk format, but none of it is labeled anymore. So it might as well be lost, as it's not worth me going back though and trying to rename all 30gb of information. I have the 64gb card in the phone right now and it seems fine.... Just empty. Haha.

If you haven't done anything to the 32gb card, try using testdisk. It's a free utility that can recover files. I had that happen to my 64gb sd card on a Vista laptop and was able to recover what I needed off it, my nandroids, backups, pics, etc... Also recovered everything off a 500gb drive that all of a sudden Windows was telling me wasn't formatted.
http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step
I just got my new Win7 laptop so I was wondering if I should hold onto my pos Vista one to read the 64gb card.
I know this is technically a question, but I was hoping to spark some discussion on filesystems in android.
I just got a 64GB microSDXC card and I know that the LGOG is compatible with it. I just checked and noticed that:
a. it comes preformated with exfat and
b. my ubuntu install is not cool with that.
I'm all linux over here, so I'd actually prefer something like ext4, or something more flash-storage specific (forget, but there were several flash-friendly FS's in the works way back) and I'm just fine with the 'other OS's' not being able to mount my microsd card.
The primary concern, of course, is what the LGOG is gonna require. At first I thought this would have to be exFAT, but seeing as FAT32 supports up to 2TiB, maybe FAT32 is still the only option? I tried ext4 in my xperia ION, and it wouldn't mount unless it was FAT32.
If you want mount it in CWM , I'm pretty sure it has to be FAT32.

good point, though at this point I'm unlikely to use CWM on this device, though, that could change. I've just read that many people are opting for NTFS on their sdcards in android to avoid the 4GB file-size limit of FAT32. I had no idea android supported NTFS, though linux support is quite good at this point apparently, so that makes sense....
I formatted NTFS (in linux, tho) and the stock LGOG firmware refused to mount it, so I guess I'm stuck with FAT32....

You can format the SD cart to ext4 using Gparted and it should be usable and much faster than FAT32. I've formatted my SanDisk 64 SDXC to two separate partitions so that I can utilize the primary partition for storage and the secondary partition for apps synced with Link2SD. Works quite nicely formatted into two 29GB partitions.

I'll have to download a live CD and try that out.
I'm also primarily a linux user. I have been using fat32 on my 64gb class 10 card and recommend it for convenience.
I did try exfat and although I did not run benchmarks, I think exfat is slightly faster (and I'm sure ext4 would be faster that fat32). However, you cannot beat the convenience of downloading a zip file straight to your card and installing via CWM all in just a few minutes.
It's no ext4 and so I lose a tiny bit of peace of mind, but it's worth it.

Yeah I formatted mine into one 50 Gb partition (User) and another 9 GB partition (apps) and Link2SD works great. However, for apps that download additional data into the obb folder it doesn't move that over. Another thing to note is the highest app that I linked only saved about 50 MBs. Not really saving that much space but after I linked several 50 MB and under apps, I recovered about 1 GB of space on the Internal. It's worth it and not that complicated.
I you want to try: Backup your SD, format it to Fat32, use MiniTool to resize the first partition, then create a second partition (FAT 32 and make sure it is Primary, Don't use ext4 it didn't work for me) using the remaining space.
EDIT: Even 9 GBs is too large. Anyone who is gonna try this, you would only need about 3 to 6 GBs for Link2SD. I also tried using GL to SD in combination with Link2SD and had some issues.
Okay, in the morning I'll make a 50gb the exfat partition for use in android and a 9gb FAT32 for recovery.

I think you misunderstood. The first partition will be used for files and recovery in android and must be FAT32. You can use another format but I haven't tested any others. I also know the recovery won't recognize any other format besides FAT32. The second partition can only be used for link2sd and the only one I got to work was FAT32.

All you have right about sdxc ExFat format. Look at your sony site there is an info/statement about sdxc. Check, its there where are news about update . These sdxc formated are incompatible with sgpt 111/112/ 113 NOW . Maybe in future will be comp - who knows . I didnt check xts statement.
...but koto u can change sdcard format to Fat32 and you will have working with tab card.
I personally have same card as you but microsdxc 64GB with sd adapter. I resolved this problem by formatting it with my android phone (lt18i .4.0.3) .Exfat changed to Fat32. You can format it also via PC tool ( my case : I formatted my card first on PC win xp and after I have 32Gb card instead of 64. After that read somewhere that some OS ( windows generally) have restriction of reading Fat format to 32gb - but it doesnt mean that it cant read it. ) . Linux should read and be able to format to fat32 >32gb sd . Search 3 rd party app for pc to formatt.
Btw i have 4.0.3r5a,I can confirmed this card working also on ( 4.0.3.r5 ,4.0.3r1)
koto99 why you want to have ExFat formatted one ? transfer >5gb?You can also plug external hdd with ntfs and drive mount app with rooted tablet. Drive must have external dc to give own power supply.

Also asked about tool app to format inside tablet( most tablets don't have that option). Check the tech repply esp "the only consequence".
Dear Customer,
Thank you for emailing SanDisk Technical Support. It is our goal to make sure you have all the resources you need to get the most from your product.
I understand that in exFAT, the 64GB microSDXC card is not detected by your Sony tablet. This is because the tablet doesn't support exFAT. After formatting the card in FAT32, the card seems to be working fine in the tablet and shows the full capacity.
The only consequence you may experience by doing this is that you won't be able to add any files larger than 4GB, due to the FAT32 limitation.
Transferring a 4GB or larger file to a USB flash drive or memory card http://kb.sandisk.com/app/answers/detail/a_id/289/kw/4GB
You will be able to format the card back to exFAT, if your operating system also supports exFAT: Operating Systems that Support the exFAT File System http://kb.sandisk.com/app/answers/detail/a_id/3389/kw/exfat
If I understand correctly, you would like to know also if there is a difference between the microSDXC card and the SDXC card. There is indeed a physical difference between both cards:
- microSDXC: SanDisk Ultra microSDXC UHS-I card for mobile devices www.sandisk.com/products/memory-cards/microsd/ultra-class10-for-android/?capacity=64GB
- SDXC: SanDisk Ultra SDXC UHS-I Card www.sandisk.com/products/memory-cards/sd/ultra-uhs-1-class10-30mbs/?capacity=64GB
Regarding your question about the format option tool for the tablet, there currently are no development plans on this. You may keep an eye on the SanDisk webpage to see if there would be any plans on this.

BR biablo
The EaseUS Partition Master 9.2.1 Home Edition not Show SDCards.
I can click refresh to the next Christmas.
Is not Show my 32Gig, it Show only HDDs. (SSD, HDD and USB)
I use now Acronis Disk Director 11 Home
See Picture
Cluster are 32
And Now!!!!
Come here i give your a Kiss.
My Hero NOW the Tablet see the Card.
Really im have lost my hope, that the Card work anytime.
I have it Formatted 40-50 times.
Really big THANX to you. GREAT USERs and FORUM.:laugh:
I accept a kiss but only from your older sister ( if you have a sister) Thanks goes to all people hands-on this topic and psxpetey who re: my pm msg that his sandisc sdxc 64gb (not micro) is working well with tablet ..yhm ..sth also about exFat, if I were s.ony oem dev I would implement exFat support to jelly bean update in sgpt. If not next thought is about porting exFat resources from xperia s tab. Easy 2 say but not 2 do with limitations we've got.have a nice weekend guys.
Does S4 support 64Gb SD card formatted as ext4?
It is currently formatted as vfat and, I think, I have just ran into its limitation: one of my directories contain over 18,000 files and no more can be added. I do not have an option of reducing the number of files in that directory or splitting it since it is controlled by an app (Anki).
I guess, one of the options is to use internal storage that is ext4 and would not have such limitations. But I would much rather keep those files on SD card if it is possible format it as ext4.

ext4 is a native Linux/Unix format which is what the Android OS is based on. ext4 will work fine on an SD card. If you connect your phone to a Windows machine depending on your version of the OS and drivers you have loaded it may not recognize it.
Your card is probably actually formatted as Fat32. VFAT isn't a real format type. It is just a notation for a FAT partition with long file names.
The one issue is that there have been a lot of people having issue with 64Gb SD cards on custom ROMS and kernels. If you are running a custom ROM or kernel and your card is currently working, I would check the support thread before making the changes.
One other thing to point out. It may be obvious, but I've been doing IT support and programming for about 30 years and have learned its best to point out the obvious before data is possibly lost. Unless you have a specialized utility to convert the SD card partition to ext4 from it current FAT state, it will erase the data in the process leaving you with a blank SD card. So make sure you back the data up somewhere before you make the conversion.
Hopefully this helps.

I do not touch Windows, only Linux. So this is not a problem. However, I remember back a year or so ago I tried to use ext4-formatted SD card in my old Droid Incredible and it did not work and I had to switch back to fat32. But maybe older version of Android supported only older versions of extX file system?

I vaguely remember reading somewhere that for S4 to recognize 64Gb card, it should be formatted only as exFat. I do not remember if I had to format the card myself or it worked out of the box. I think it did but I did not so far had any problem using the card in S4 (maybe there will be a problem once I use more than 50% of storage?). What tool is aware of exFat and can say for sure if I have fat32 or exFat? The tools I tried so far just say vfat.

My phone is rooted but otherwise I am running stock kernel.
I'm a Windows programmer who is an average Linux/old time Unix user. VFAT is how Linux sees any FAT partition with long file names. I have plenty of tools that will specify the difference on the Windows side, but I'm not real sure on of any free tools the Linux side. I have a couple of paid tools for doing computer security forensics that are Linux based that can tell you the exact format type so I know it can be done.
I'm running Hyperdrive with the stock ME7 kernel. I just searched through the thread and the only ones who got the 64GB cards working were using custom kernels. They were also the only ones who appeared to get the ext4 working consistently on the S4.
I just did a quick experiment. I had an extra SD card around (not a 64GB) and formatted it as ext4. My S4 would not mount the card. It would see it and tell me that there was a blank SD card there or one that has unsupported files.
Sorry I couldn't be more help.

I was actually hoping that Android itself might have some tools to recognize such things since it seems to depend on it so much.
Since I put my S4 into an Otter shell, I no longer take SD card out unless absolutely necessary since it is such a pain to dress/undress the phone. So far Android System Info and DiskInfo seem to give the most detailed info about the file systems but even they just say vfat for external SD card.

The /system/bin/mount command executed from inside Droid Command Pro gives a lot of details but still says 'vfat'. Can one deduce from the rest of the output if it is fat32 or exFat? See the attachment.
Try this app:
https://play.google.com/store/apps/details?id=com.sylkat.AParted
I know my SD card is FAT32 formatted. I formatted it as FAT32 on a Windows machine when I got it. This is the only app I tried that shows my SD card as FAT32. The rest all reported VFAT. Once it's loaded look under the tools tab. It should display all the partitions on your SD card.

Yes: it shows fat32 for my card as well. The question is: would it show exFat if it sees it or also classifies it as fat32?

They would show up differently if the aParted supported ExFAT (sorry didn't know).
FAT32 and ExFAT are 2 different formatting structures for partitions, with 2 different boot sectors and different file allocation table (FAT) sizes and structures. With FAT32 in the boot sector of the drive starting in byte 3 it will show either "MSWIN4.1" or "MSDOS5.0" then starting in byte 82 (size 8 bytes) it will have "FAT32 ". With ExFAT starting in byte 3 (size 8 bytes) it will have "ExFAT ".
I just format my test card as ExFAT and aParted gave me an error saying extended partitions detected, that they weren't supported, and the display information may be incorrect. The information for the partitions was blank. So it did recognize the difference between FAT32 and ExFAT, but couldn't display the ExFAT information.
I did find this application yesterday ( https://play.google.com/store/apps/details?id=me.kuder.diskinfo&hl=en ). I display a FAT32 partitioned card as vFAT, which it technically correct. That is a FAT16 or FAT32 partition with the long file names. I just checked and it will display ExFAT as ExFAT.
Hopefully this will help.
