Usb not accessible because of I/O device error

#1 Post by Gloria8733 » 15 Mar 2019, 10:01

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
Once it's done, remove the original device and run chkdsk on the clone.
