ddrescue has completed! I’m about to let this image to a new drive to recover the non-system files which were unreadable. But I do want to compare-and-contrast something. Here’s ddrescue’s completion output. Note in this list:

  • 5.49 gigs of errors (recovered, tho’ it took four days of processing
  • 21261 read errors.

Yikes! Clearly the drive is on its last legs! What does Hitachi’s SMART firmware think?
