I've always used extFAT on my SanDisk 64GB MicroSDXC UHS-1 Class 10 memory card. A few times I tried FAT32 but the S3 still had issues with it so I went back to extFAT. If I was to format the card now to FAT32 would any of the following happen.
1. Card could die sooner because it's FAT32?
2. Are there known bugs with having it be FAT32?
3. Does the speed or performance of the card drop any?

FAT32 vs exFAT (aka FAT64)

1. No
2. Windows will not allow you to create a filesystem larger than 32GB with FAT32, you can use 3rd party programs to accomplish this.
3. FAT32 filesystem performance depends on the size and number of files contained on the fileysystem, many small files will cause FAT32 to be slower than exFAT.
ExFAT also supports ACLs (file permission attributes) and does not have a 4GB single file size limitation.
There is no practical reason to use FAT32 over exFAT unless the devices you are using are incapable of reading an exFAT filesystem (i.e. pre-XP versions of Windows).

I was only thinking this because of being stuck on CWM making a nandroid backup and such since I can't remove the recovery.

So I figure some people have purchased SDCards other than what HTC provided with our phones...
My question is: What format (based on card size) should we be using?
I had my SDCard (16GB Patriot Class 10) from my Incredible formatted as Ext4 which was causing me a major headache when I wanted to do a Nand Backup. My AmonRa and Clockwork could NOT mount the sdcard. Took me forever to remember that I had formatted it differently. I put in my old 8GB card that was FAT32 and all of a sudden, I could successfully do a Backup.
The catch is that since I am using a 16GB card, when you format (NO Quick Formatting I know) you have multiple options for Allocation Unit sizes. What size should be used?
Reason being is that I formatted the 16GB to FAT32 and default was 32kilobytes as the Allocation size and still I cannot mount the card in AmonRa.
Please help. Thanks.
I have the identical card I believe and I was using Fat32 Default allocation (which ends up being 4k I believe).
Also why were you using ext4? You do know you can partition your card so that you have both right? I can't think of a reason why you would need a 16gb ext4 partition.
What about a 64gb card? I read that someone put one in and had the phone format it and it works fine. No idea how they formatted it, they didn't mention it, so I didn't know there were options until seeing this thread. Got a 64gb card for xmas and would like to pop it in and load it up! Thanks.

I read elsewhere in the Rezound Accessories forum that if you format a 64g card FAT32 the phone should be able to handle it.

Directory Bind works fine with the Samsung 16gb class 6 card but when I use the Sandisk 32gb UHS-1 card the binding process all goes though green like it should but when I start the Apps I moved the data on it just can't find the data and tries to download again, and I formatted both cards multiple times on the phone and ran benchmarks which show read/write speeds are what they should be, so any idea why this is happening?
What filesystem is your SD card formatted in.
Don't use the exFat but format it to Fat32 with your computer.

Hi there guys
I have been having a problem with 3 sandisk 64gb micro sd cards. I always got them replaced but it is getting frustrating now. Obviously they are formatted in exfat format.
The problem starts when I copy data of over 30 gb. Once i copy the data n the sd is remounted or the phone is restarted i always get the message "damaged sd card" but when i read the card on pc through an adapter it shows the contents ok. So i want to know if anyone can help me so that I may not need to return the card this time around...

Try to format it first in the phone, then start loading data on it.

I also tried it buddy but none of the methods seem to work .. i also tried formatting it then copying data through sd card reader as well as the phone itself... does it have to do anything with some file system issue or kernel related issue... im on stock kernel rooted...

also had the same problem. i formatted the card to fat32 with 32xxx sectors with "GUIFORMAT" app for windows, the it works ok.
then after fat conversion, you can try to format the card to exfat using any app (not the windows one) search google, then it might work, didnt try myself as fat32 works great, and i can use it with the script that makes the card the phone memory, so now i got 64gb instead of 11.6gb of phone storage

where formatted?
how much fully card with data?
witch rom, kernel?
I have the class 10 64Gb Sandisk sd card too with no problems.
Card has about 55Gb info on it and I didn't format the card. Just put it into the phone. Recognised instantly and haven't looked back.
I have a 2nd SGSIII too with a 64gb class 6 sandisk sd card. Same applies but with a little less data on it.

Hello, new micro sd card 32gb class 10 i think
What is the best file system to format it?
Thanks!
I' a noob so weight my words but I went with NTFS and everythibg is still ok.
*except my typing
Format it with the original file system of the sdcard, so you surely won't have problems, but if you're using the CustomRom Cyanogenmod it won't work with exFat, cause CM doesn't support it because of licences!
Use the phone to format the card and you should be fine. If you want to select the file system yourself, FAT32 works on 32GB cards and is the most likely to work well.
Fat32 is best for compatibility. ExFat is best for performance

Fat32 has a file size limit of 2^32 bytes (hence the name Fat32) which equivalents 4GB
If you have files (movies, ...) which are larger you need to use another filesystem.
Exfat support is very bad on linux and thus can lead to undesired results including data loss. Go with EXT4 (optimal choice) or NTFS but note that you will not be able to use a cardreader when choosing ext.

Just bought a new sandisk 64gb card. When I try to mount the SD card I get "damaged card" notification in my status bar. I selected it and it gave the option to format. I did but to no avail. Will this ROM support that size?

I ran into the same problem before. Sadly, the Note does not support 64gb sd cards. The max that you can get is 32gb, unless someone out there can prove me wrong.
Been running a 64GB samsung card in my I717R since release date without issue. I did originally format the card in another phone.
If you need help please use the correct forum. Moved
Is the card formatted to NTFS ?....or FAT32?
also ....is the card an SDXC card ?
Been reading for a bit to attempt helping, and the card should function fine if first formatted to FAT32, but as stated by agoattamer ..cannot be done by the usage device.
Perhaps via card reader and PC ?
Hope it helps a bit ..g

I am using a Rogers branded Note with stock ICS. I purhcased a 64GB Sandisk MicroSD a while back. Out of the box, it would not work, as the card was formatted in exfat. I had to format it to FAT32 first.
Unfortunately windows 7 did not allow this.. I think the card was too big. So I had to google how to, and used a free utility to do it (sorry, I do not recall the name of the app).
Works great now
I did find a fat32 software that works. I only got 59.45gb out of it. I used 32768 for the allocation size.
Would a larger allocation size get me the full 64gb available?

You won't ever get the full 64GB. It is just how it is. Check your hard drives on your computer and you will find the same result.
