  1. Using Acronis True Image you schedule a task to back up to a hard disk, or to validate a backup on a hard disk;
  2. Some time later you take out the hard disk and plug in a new one;
  3. The scheduled task fails.


Every hard disk has a unique ID. Acronis True Image searches for this ID to proceed with a scheduled task. Once the hard disk is switched, there is no ID to which the task is scheduled. Hence, the task fails.


Recreate the scheduled task.

If you are planning to switch the hard disk drives, create a separate task for each of them.
