Hi I have a 32G toshiba usb that is very important to me. every time when I try to access it I get this message "The request could not performed because of an I/O devices error" I searched on google to find the solution and the most appearing solution was to run this command "chkdsk /f m:".....m being the name of the drive.

I tried this but i get message "Cannot open volume for direct access"

You should try to clone your USB key using ddrescue as described in https://www.cgsecurity.org/testdisk.pdf
Once it's done, remove the original device and run chkdsk on the clone.
