I've got an external hard drive (200GB Cavalry, it's been working swimmingly for the last six months) that recently started giving me "I/O device errors" when trying to save or move large (over 700 MB) files to/from.
I've already done some troubleshooting (switched USB cables, tried using it on a different computer) to determine that it is in fact the HD and not USB drives, a specific USB port, etc. The computers I've tried using it on all use Windows XP.
If the drive is dying and I run CHKDSK on it, is it possible CHKDSK will make it worse because of its attempts to automatically repair files?
Thank you for any assistance.
