Key concepts

SMART warningsclicking and slownessimagingminimising stress

The lesson

Warning signs: SMART warnings, clicking, very slow reads and files that will not open.

Every hour of use can make a failing drive worse. Copy the most important files first, or create a full image with tools that skip bad areas and retry later.

Work from the image rather than the original wherever possible.

Step by step

  1. Read SMART data from a lab drive.
  2. Prioritise files with the owner.
  3. Create an image.
  4. Recover from the image.

Practice activity

Image the prepared 'failing' drive and recover files from the image.

Expected result: An image created and files recovered from it.
