I have a 250gb My Passport external drive (#WXE408lr5654). I was intending to do a backup from my IBM thinkpad, but by mistake selected “create rescue media”, instead of the backup utility. Yikes! Now my thinkpad only sees the drive "IBM_USB(Z:).All the files (other backed up files) on the external drive seem gone (or at least I can’t see them from my thinkpad). Any ideas on how I should precede, if it’s possible to restore the drive to it’s old condition with the old files?
