I salvaged a 128 GB HD from a friend's Windoze laptop he was chucking iut. On it were 1.28 GB of photos, of which 1.1 GB were worth keeping. These I made into a DVD using Toast.
I had hoped to use the HD for backups but won't now. TechTool Pro monitors attached storage & reports that it's failing S.M.A.R.T. testing. There's some magnets in the drive I may be able to salvage.
