Prerequisites

  • Are you running the latest version?
  • Can you reproduce the problem in the debug version?

Check and fill as appropriate:

  • I was running Aaru under Windows 10 20H2...
  • ...in 64-bit
  • ...using an Intel / AMD processor
  • Device manufacturer: Unknown
  • Model: Essentials
  • Bus:
    • USB
  • I was dumping media (disk, tape, etc)...

Description
