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!

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.

Important files = Backed up files

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