I am running Windows 10 and am attempting to view files that are on a SanDisk Ultra 32gb USB 3.0 memory stick.

It shows on (D:) drive as EFI and when I click on it nothing is in this drive. When I check properties it states that there is 2.00 kb used and there is 196mb of free space.

I have checked online and believe that my computer is viewing a partition. When I plug the usb into my phone and tablet it asks me to format it. As I am unable to access these files anywhere else I do not want to format it as I will lose these files.

When I view Disk Management it shows 3 partitions:

200mb healthy (efi system)

  1. 65 gb healthy (primary partition) 128 mb unallocated

I believe that the files were put on the usb stick with a Mac although that is an assumption on my behalf.

Formatting is not an option for me though as I am unable to get the original files.

Checked the computer first for viruses then do this:

  1. Run cmd - Navigate to Accessories>Command Prompt (Run this with Admin rights)
  2. type attrib . X: -r -s -h /s /d (where X: is the drive, this is your flash drive letter)
  3. you can invoke other commands by typing attrib /?

I've solved the problem - the partition was showing unformatted and windows wouldn't let me do anything with it without formatting, which was out of the question! if anyone has the same problem I downloaded Easeus data recovery wizard and this enabled me to recover the files.
