How would you go about formatting it on the EVO. Settings>card>erase SD card?
Sent from my PC36100 using XDA Premium App

Use RA recovery. You will see partition SD card. You have 3 choices. Swap-set to 0, ext-2-set to 1 gig and fat 32 for the rest. You have a big card so 1 gig ext-2 is good for apps to SD. Just make sure you backup what you want to save first.

is it a genuine Sandisk? there are a LOT of Chinese fakes on eBay, some barely work, while others don't work at all...
use any of the methods described in the other posts to format it, you can use either the phone or your computer.
good luck!

Thanks guys I formatted it thru my settings and then did a partition thru Amon Ra thing seen to be going ok. SO FAR. I hit the thanks buttons tomorrow when I get to a computer.

This is probably the case. A lot of flash-memory based devices on eBay have 128mb of usable memory and the controller continually overwrites it as it writes to anything above the 128mb ceiling. So... your ROMs would be bad, your pictures would disappear, everything would be broken after the first 512mb is full. Keep in mind that the file table would be in the first part of the drive so all of your files would actually appear to be on there.
Here's a good story with an example: http://technogra.ph/2011/05/05/man-...-drive-disguised-as-fake-samsungs-hard-drive/

Your right Jason. I formatted this thing til I was blue in the face and still no dice. Yup I got burned. Teaches me to not buy from the damn Chinese anymore.

No Need, I use my stock 16GB and write at 7MB's and read at 22MB's Just use Sd Booster and set cache from 128kb to 1024,2048,3072,or 4096. So I went from like 2MBs to 7Mbs and went from 12 to 20ish

yeah cause all it does is make your cache files bigger which in turn drops your capacity a bit

ok so then tell me this when i go from 9.85 avil space b4 sd booster to 9.20 avil space without adding anything to my sd card hmm me thinks sd booster just changed my cache size to store files in for faster loading which in turn uses up some of my storage space hmmmmm how interesting

Most definitley true but imagine a 32GB or Hell even a 64GB Micro SD Class 10 with the cache bumped to 4096kb haha That's fast speeds were talking about now

I would not - sequential read-writes are slower in Lexar and Patriot vs. SanDisk (had first hand experience with all 3 brands). I was using the card to run CM7 on Nook Color from uSD, and the only one that would work was SanDisk.

The Sandisk 64gb Ultra is looking mighty tempting at the current price.

The phone formats in fat32 like the pc. So in that aspect no. The reason I said to format it in the phone is because the 64GB cards usually come formatted as exfat. Exfat is better in that is handles large file sizes, is more efficient and has better error handling. In a simplistic example it is like ntfs for flash drives. The issue is that no recovery supports it and none have it on the horizon due to licensing issues. So if you never plan on using the sdcard from recovery I would format it exfat. But by you being on this forum I doubt that is the case. Which is why I just recommended that he format it in the phone. I tend to ramble when I am driving so sorry if this is out there

Nope. It may have something to do with the fact that it's one of the newer ones, that is, the class 10/ U-1 ones. My captivate told me it was damaged, and my Note didn't even see it, perhaps because both can only take up to 32 GB.

What rom where you using when you tried the 64GB sd card.? I'm on the verge of ordering a 64 to try it out. I'm using CM10 nightlies, maybe this would make a difference in reading the card?

I replied to your thread already. it's a hardware problem, it's not something you'll fix with a software. It simply doesn't have the technology to read 64gb SD cards.

When I bought mine they told me the max SD card was 16 GB, that was from someone at rogers that probably doesn't know what they are talking about though

64g NTFS micro sd card for the Captivate.
I have a Sandisk 64g class 10 manually mounted on the Captivate and have never
had any problems so far. The Paragon NTFS app was installed and auto mount
options were disabled. A new folder was created inside the sdcard0 for easy
access. Manually mount the card and go to advanced mode to specify the empty
folder in which to mount the card. I named mine NTFS-64g, once mounted the
card will be readable and writeable as well. Hope it works for you too.

I figured something might be possible depending on how it's formatted.

Captivate SGH-i897 External SD Card
Captivate is only allowed to accept 16 GB External MicroSD Card
With Internal and External thats total of 32 GB which the phone will allow
I suggest getting:
Sandisk 16GB Class 10 MicroSD for External Card
Captivate comes with 16GB internal storage, along with a microSD slot which supports up to 32GB

Format 64gb. Sandisk micro SD to fat32

First and for most I am not responsible for anything that might happen to your phone, computer, or sd card. I am simply posting to help anyone ot there who might have an error with there new cards.
So along with alot of others who jumped on the 64gb micro sd sales I purchased from best buy. When I tried to get my phone to register the card which was originally extfat by default it wasnt recognized. So then I tried formating to ntsc to yet again fail. I finally tried to convert to fat32. What follows is a guide to get uou 64gb sd card to fat32.
First make sure you backup any info you might have on you 64gb. Card because formatting will erase EVERYTHING.
Second, connect your micro sd to a computer. I personally used the micro sd to full sd adapter that came with my card.
Third go to the following website
http://www.ridgecrop.demon.co.uk/index.htm?fat32format.htm
And download the gui app by clicking the picture.
Fourth run it. Make sure you select the right location to were your sdcard is.
Fifth click the allocation to your preference (im not sure what this is suppose to do but I set it to max roughly about 64-65) then make sure you select the right destination if not you can format your hdd on the computer. Then press the quick format and start button.
Sixth the script should take less then a min. To be done and have a formatted fat32 64gb microsd card..

How common is this issue? I've got a 64GB Sandisk with exformat in my T889 with no apparent problems (so far).

Im not to sure how common it is but I ran into trouble. I tried the default for the card then ntsc and it wasnt registering with my phone althought I must say I was running perseus kerenel with the memory swap script. Then after I formatted to fat32 it work. Not sure were I read on some other people running in to trouble with the same sandisk card until they formatted.

I bought Sandisk 64gb card from best buy..my phone reads the exfat card fine..but when I use mtp transfer my computer recognizes the card as generic hierarchical and limits my file size..is there a way to Mount the actually card as exfat without removing it from my phone?

It'll format it but it says 27GB not 59GB so it's only seeing half of it.

Hmm. I dont even know there's an issue like this. I bought my card online 64GB Sandisk Class 10 during the Thanksgiving sales and its like plug and play since then. No problem at all.

I've gone through 2 64GB sd cards. They work for a while and then something odd happens. I write to the card but the file is gone if my phone reboots. Permissions issue maybe?

I just had the same thing happen to me..I downloaded a bunch of albums..they were there..then I rebooted and they were gone...but when uTorrent was downloading it told me I didn't have enough space..I told it to go ahead anyway...they made it but then disappeared..

I have had my 64gb. San disk for about a year and a half without any issues. I formatted the way I outlined in the first post and it has been smooth sailing ever since. I know that the first post could be a bit tedious but it is the RIGHT way. No short cuts. I did have an issue with some kerrnels. For example saber kernel from Jedi Roms says that it can swap your memory partition from external to internal and it does for about a week and then for some odd reason it just locks your SD so you can't download or delete any thing. The combination I have been using is an old school pegasus kernel with a memory swap script. I have been using that for a long time and not only is it the most stable memory swap, but the kernel has never messed up my SD either. P.S. just my 2 cents
