"Error writing subchannel to output image, not continuing..." #161

Closed TheRogueArchivist closed 6 years ago

TheRogueArchivist commented 6 years ago

Prerequisites

Check and fill as appropiate:

Description

When reading a CD-ROM, DiscImageChef tells me "Error writing subchannel to output image, not continuing..." and stops.

Exact command line used:

DiscImageChef.exe dump-media -i E: -o test.mds

Expected behavior:

It should dump the CD-ROM without using -f to force it (which seems to work).

Actual behavior:

"Error writing subchannel to output image, not continuing..."

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

Output of command execution with debug output enabled

I tried on the newest commit and it works now! Thanks for fixing it so quickly! :)

Please note that part of the code is still work is progress and I have not checked that the images are readable by other software or even contains correct data. Particularly I don’t even have Alcohol installed to test if it reads the images I create.

Both alcohol and wincdemu mount it properly and I can convert it to iso just fine, so it looks pretty promising!
