Usb not accessible because of I/O device error

#1 Post by Donna334 » 29 Jan 2019, 06:39

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" Psiphon

Try to clone your USB key using ddrescue as explained in
If it works, open the image file using PhotoRec
If ddrescue doesn't work, you should contact a data recovery company.
Good luck
