Error -205 lost access to storage media
If error 102 accompanies error 205 see "SCSI Issues" in the Retrospect Users Guide. If error 102 does not accompany error 205 and SCSI communication problems have been ruled out the next step is to check for media failure on the source volume.
Some hard drives reset the SCSI bus when they sense they are experiencing a media failure. Try testing the hard drive with the software that was originally used to format it.
