Passport could be read on all 3 computers - suddenly stopped working on desktop (Windows 7 Ultimate 32-bit) - Still can be read on Vaio (Win 7 Pro) and very old IBM with XP
have updated driver (SES), reformatted drive & run WinDig
have ensured that all permissions are granted to all users, system, etc.
on Vaio, Passport shows as passed & no problems; all files can be accessed
on desktop, full test “fails” due to too many corruptions
Any thoughts on failure to recognize. Neither WD nor MS has a clue.
