Usb not accessible because of I/O device error

#1 Post by Leslie198 » 17 Jan 2019, 12:13

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" MyBKExperience ;)

There may be bad sectors or it may be a more serious problem like a damaged head.
You should try to clone the disk using ddrescue as described in https://www.cgsecurity.org/testdisk.pdf
If it doesn't work or if it's too complicated, contact a data recovery company.
Good luck
