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...
  • ...in 64-bit
  • ...using an Intel / AMD processor
  • ...using an ARM or Apple Silicon processor
    • Image format: BWT
    • Application that created the image: BlindWrite 4
  • I was converting the image...
    • ...Destination image format: ISO
  • I was listing the filesystem contents...
  • I was extracting the filesystem contents...
    • ...Filesystem:
    • Analyze command recognizes the filesystem
  • I was creating a metadata sidecar
  • I was checksumming the image
  • I was verifying the image

Description

Trying to convert a BWT file to ISO results in an ISO that the verify command reports unknown sectors on. Aaru is also unable to find a partition to extract in the original BWT, but I'm not sure if this is a bug in Aaru or in BlindWrite 4. Converting to an Aaruf image creates a seemingly working image that verify doesn't find unknown sectors in.

Exact command line used:

aaru i convert .\BWT-BlindWrite45.BWT .\BWT-BlindWrite45.iso -f

Output of command execution with debug output enabled

From "aaru -d i verify .\BWT-BlindWrite45.iso":
