Hi all.

I recently found a 64GB SD card with a broken casing and no label on it. I took it home and re-cased the chip it in a 4GB SD card case. I had to do some work with a craft knife to get it to fit but I was successful.

I put it in my USB SD card reader and it opened up explorer but it had no files on it.

I decided to use Windows to format it and selected the default file system which displayed as exFAT.

I formatted it as exFAT which completed fine but it won't recognize in my Canon camera or Hitachi professional camcorder, both of which state they take 64GB SD cards.

I tried to reformat using windows again but the only other option I get is NTFS which it will format in but again is not recognized in any of my devices.

I tried to use the 'USB format tool' that is used in the making of 'Hirens BootCD' and that does give me the FAT format option but if I use it I get a 'file system too large' error or something like that.

I also don't know what the speed of this card is as there was no label on it.

Has anyone got any suggestions or should I just bin it?

Hello... Yes the Max VOLUME size for fat32 is 2TB... Try deleting all partitions on it first, then try a Format at FAT32 on it... Your camera has it's own format type to handle the 64gb, and can be done in the camera.
 


How do I partition an SD card in Windows 7 Ultimate x64? Disk management?
Do I format 3GB as FAT32 and the other as NTFS and then try it in camera?

 
Hello... Your camera has it's own format type to handle the 64gb, and can be done in the camera.

OPPS....Yes the Max VOLUME size for fat32 is 2TB... ME BAD B )
 


I'm using Minitool Partition wizard but it will only create a 4GB maximum FAT32 partition. If I try and format the other partition to FAT32 it says 'Warning: Windows only recognizes the first partition on removable media'.
 


The camera won't acknowledge the SD card has been inserted so I can't use that to format it.
 
Hello... Does your camera maker have any suggestions on their site? or have an APP or Tool for use? Do you have a switch on the SD card in the wrong position? like a Protected mode?
 
Hello... Maybe, it's not the size of the card that matters here, For compatability, BUT the type of card for your cameras?... not all SD cards are the same... SD, SDHC, SDXC.
 
Wait a minute I wanted to format a 128 gig SD card using FAT32. Well tried windows 7 and it wouldn't format it FAT32. So I go to the bottom of the screen on the left in the run type MCD which takes you to the dos prompt. I type format /FS:FAT32 X: where X is the drive letter of the SD card. It starts formatting about 3 hours latter it say cant format the card because it to big something ti that extent. It dud fimat tbe card in a second exfat which it does for SD cards. Now I read you can format 2 terabyte SD cards please tell me how. FAT stands for file allocation table and this file allocation table is 32 bits so how can you do 2 terabytes I can't even do a 128 gigabytes SD card because the volumn is to big and I can understand that.I just really need to know I can format a 128 gigabytes because I need it formated FAT32 for my quadcopter.
 
Windows no longer allows you to format large drives as FAT32 to try and force you to use their proprietary format NTFS. FAT32 is absolutely capable of being used on large volumes, up to around 2TiB.

Download the open-source tool GParted, follow the instructions to burn it to a disc/USB, and use that.
