I just formatted my card to FAT32 and i notice it has 58 GB out of the 64. Is this the default value or did i format wrong?
You can use all 64GB. Its just display as 58GB due to the difference in calculating memory size.

I partitioned my 8gb card before so I could use apsd and I don't use it anymore so I formatted my card and it still only tells me there's 6700 mb available.. I know some of the card will be taken up with software to make the card work but I didn't think it would be a gig.. did I format the card wrong?
if not the whole reason, most of the reason is that when the manufacturer makes their claim of 8GB, they are using the formula of 1000B being 1KB, 1000KB being 1MB, 1000MB being 1 GB, then when systems read the card, 1024B is 1KB, 1024KB is 1MB, 1024MB is 1GB...
so if the card is 8000000 Bytes claimed by the manuf. then 8000000/1024/1024 should be 7.6 gigs
my 8gig card shows 7.39 in my phone, so maybe the OS reserved 200MB for something?

If you partitioned your SD card for a2sd reformatting won't give you back the whole card. You need to repartition and select 0 for swap, 0 for ext and 'the rest' for FAT. That will repartition it into something your phone (and Windows/Mac/etc) can see and give you back the full available space.
Ok so this is my problem:
I have a 16 Gig MicroSD class 6 card.
I've partitioned it with ROM manager and then manualy changed the partitions sizes, I've increased the ext3 and the swap partitions sizes with gparted.
Later on I've inserted the card back to my Device and Flashed a fresh copy of the ROM.
The device still can only see 147 Mb or free space whereas I've partitioned it to be about 1 Gig of size.
Any one knows any way to make more space on the card then ~150Mb?
Do a search on data2ext and data2sd.
Good luck.

I take it your using a normal app2sd rom, not the newer data2sd or data2ext.
where are you looking to find your stats? if its in settings/sd & phone storage these wont show the amount of the app2sd partition, but they will show the amount of a data2sd or data2ext partition, because the latter two fools the phone in to thinking its internal storage, the former just moves parts of an app to the ext partition on the sd card so isnt classed as internal storage.
If you download an app from the market called quick system info it will show you the size of your app2sd partition to see if its worked
I just received this in the mail and I was wondering where do I start in terms of formating format and allocation size? Also, how would I check its true capacity and transfer rates?
put it in the phone & let it format for you, it formats exFAT but I was using a 64GB card. Not sure if it does FAT32 if using a 32gb or smaller sd card. If you need FAT32 then use linux or Windoze to format it & I always "default" for allocation size.
that is my question too. thanks
This is a cross post of a thread in the Q & A section because I think it is more appropriate here. Please forgive me if you disagree.
I have encountered a problem using SDXC cards in the Galaxy S III. It appears, to me, to be a bug in the exFAT drivers which are only used in the 64 GB SDXC card, 32GB cards and less are formatted as FAT32.

I heard you might need to format the card as FAT32

You can't use FAT32 on a 64GB card. The phone formats 32GB or smaller as FAT32 and the 64GB at exFAT.
Some platforms support FAT32 on greater than 32GB cards/drives but it is not very compatible.
Thanks for your help

Don't confuse FAT32 and FAT16. FAT32 supports up to 2 TB, though I believe Windows makes it difficult to format anything larger than 32 GB.

You are correct the theoretical maximum size of FAT32 is 2TB. However, since Microsoft in their infinite wisdom decided only to support FAT32 up to 32GB (most likely to force people to use NTFS) support for FAT32 above 32GB is spotty and unreliable.
This being said if you format a 32GB card or smaller in the Galaxy S III, it will be formatted FAT32. If you format a 64GB (or greater I presume) in the Galaxy S III, it will be formatted exFAT.

exFat format will not read correctly on SGSIII. I just had this issue with my 64 GB SD card. I formatted it in FAT32 and all was fine. I did use a Mac with disk utility to do the formatting though. Windows 7 was trying to force exFAT to format.

Windows Vista and above don't let you format volumes larger than 32 GB as FAT32. It's an artificial limitation on their part.
Other than that, FAT32 has been around a long time, and works fine with 32+ GB volumes. It's not great but doesn't really become spotty and unreliable till you go beyond 100 GB or so.
I'd get a Linux LiveCD and format your SD card FAT32 with that.
Partition Wizard Home Edition (win) is free and will format all your fat32 needs http://www.partitionwizard.com/free-partition-manager.html

Thank you for confirming my research. I am currently in communication with Samsung, T-Mobile and SanDisk. With any luck with potential sales in the millions they will fix it. The man at Samsung commented "We sell that card on our website we had better get it working"

I spoke with someone at Sandisk and they have heard of the problem and are researching it. T-Mobile and Samsung are also "investigating" it.
I formatted my 64GB card FAT32 and I am using it like that for now.
One problem with using FAT32 is that there is a directory size limit of 65,535 bytes total for the directory itself (not the files in the directory). I have a Titanium Backup directory with almost 12,000 files in it, all with long names. That easily exceeds the 64K directory size limit and this directory is "full" and trying to write to it generates errors.
If you have a directory with 5,000 files with an average file name length of 12 characters (rather short in this day and age) that makes the directory 60,000 bytes. If the average file name length is 13 characters the directory size will be 65,000 bytes and if the average file name length is 14 bytes the directory size is now 70,000 bytes and this exceeds the maximum directory size.
If you keep your file names to the old DOS 8.3 (11 characters) format then a directory can handle approx. 5,957 files. The actual number is less because there are other bytes in each entry used by the system (permissions, file size, starting segment, etc.).
For programs like Titanium Backup this can become a problem. Titanium backup uses long file names (longer than 20 characters) that include the date in them. I always backup my entire phone downloaded apps & data, system apps & data and system data. This is about 470 different items being backed up. Titanium Backup uses 2 and sometimes 3 files for each item backed up. I also maintain a 7 day backup history. This creates a total of 8,225 (approx) files, if each has a file name length of 20 characters that would be a directory size of 164,500 bytes.
This far exceeds what FAT32 can handle. And this is a somewhat reasonable scenario.
So, let's put pressure on T-Mobile and Samsung to get the exFAT problem fixed.
Does the OGP support exFat ? I hate the 4Gb limit of FAT32. How can I overcome this limit ?

FAT32 supports partitions up to 32 GB. If you notice, out of the box the G Pro comes with a hidden partition and an 23 GB partition as Internal Storage. I have a 32 GB MicroSD card formatted as a single 32 GB FAT32 partition.
You only need ExFAT if you plan on using a 64 GB MicroSD card. Since LG advertises that the G Pro can support up to a 64 GB MicroSD card, then its likely that the stock ROM and kernel do support ExFAT. If for some reason it doesn't, then replacing the ROM with one of the Android 4.4 KitKat ROMs will surely do the trick.

Well, I bit the bullet and formatted my 32Gb sdhc card to exFAT and the OGP can read it flawlessly. I am very pleased with the results because I got rid of the 4Gb file size limit. The only small issue is that cwm recovery can`t read or write exFAT so I have to make backups to my internal memory and then move them to the SD.

How do you format it into exFat?

Well, it`s very easy. I put it in the card reader of the laptop and formatted it in the file manager of windows 7.
