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 Linux [5.0.0.2879]
  • ...in 64-bit

Description

All commands that deal with my DVD drive return an exception if there is a disc in the drive. When the drive is empty, I get a proper result (see at bottom)

Exact command line used:

aaru -v dev info /dev/sr0

Expected behavior:

Getting information about the drive

Actual behavior:

Exception of type 'Aaru.Devices.DeviceException' was thrown.

If command was expected to work with a device fill this out:

I didn't know I could unmount without ejecting a CD. I learn something everyday. Sorry for the newbie issue.

All is great now! I'm back to archiving old CDs! Oh, and which image format would you recommend as being the most complete for saving old PC games on CD-ROM? I know .iso doesn't save subchannels. That's why I found out about aaru. Which format should I use? .ccd and .mdf being proprietary, is there and open-source alternative to those?

Thanks!

the most complete one is aaruformat. it's not yet perfect (specially for some particular copy protections), and not yet supported by any emulator, but it's the most complete for archival purposes (and it's obviously opensource).
