SanDisk Ultra 128GB

[ Edited ]

Hello, SanDisk Forums!

 

I've come across an error where I must format my SanDisk Ultra before storing a file to it.

It's a 128GB, but the capacity according to Windows, it's a 32GB.

This is wrong, and I'm not sure if it's supposed to be FAT32, exFAT, or NTFS, as well as the Allocation unit size.

 

Please help me!

Re: SanDisk Ultra 128GB

If it's new return it to the seller.  If it's used return it to the seller. If it's counterfeit your screwed.

 

New drives that size are formated exFAT.  Fat32 only supports drives up to 32 GB.

Okay, thank you for this. I was so scared, but if returning it to the seller is the solution, I'm sure I can.

Re: SanDisk Cruzer Glide 128GB

Hi there,

I have a Cruzer Glide 128 GB, ExFat formatted, which I have been using both on Windows XP and OS X 10.10.5 for quite some time without any probems.

 

All of a sudden OS X will not mount the unit, so I cannot access my info, and neither will Windows XP.

 

OS X\ Disk Utility, will not fix nor reformat it, the error being " Unable to write to the last block of the device ".

 

Windows XP's\ Computer Management\ Disk Management, detects the USB as "E: Removable 119 GB Online,  Healthy", reformats the unit to 100%, and at the end of the process displays the message " The unit was not successfully formatted"

 

Sorry to be posting this here, but I'm new in this forum and could NOT figure out how to start a new thread.

 

All help will with this problem will be GREATLY appreciated !

 

Thanks.

Andrés

I assume you are reformating it as exFAT, right?  Does OSx support exFAT?  Does Windows XP?  FAT32 won't work on the drive, it's too big.

 

See if you can reformat it on a newer Windows system.

You probably need a new card reader:
