Prerequisites

  • Are you running the latest version?

Check and fill as appropriate:

  • I was running Aaru under Linux aaru 5.2.99.3380-alpha+f78998d4...
  • ...in 64-bit
  • ...using an Intel / AMD processor
    • Image format: QCOW2
    • Application that created the image: Aaru
  • I was checksumming the image

Description

While dumping a 1Tb USB external hard drive, at the hashing phase, the following exception is raised: System.OverflowException: The input exceeds data types.

Exact command line used:

aaru m dump -f /dev/sdd output.qcow2

Expected behavior:

Hashing phase to finish to finish dumping of the media.

Actual behavior:

Dumping crashes at the hashing phase.
The resulting qcow2 is valid even if the hashing has failed.

Output of command execution with debug output enabled

Hashing sectors...
Hashing sector 1953458112 of 1953458176
Unhandled exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
 ---> System.OverflowException: The input exceeds data types.
