Prerequisites

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

Check and fill as appropiate:

  • I was running DiscImageChef under Windows [version here]...
  • ...in 64-bit

Description

When dumping various memory cards (SD, CF, and MS cards were all confirmed to have this issue), DIC reports "Media identified as Unknown.". I've tested both an external USB card reader and an internal reader on one of my computers.
CF.log

Exact command line used:

dotnet DiscImageChef.dll dump-media E: CF.dicf -v -d

Output of command execution with debug output enabled

The detection is correct, your memory card reader identifies as an unknown hard disk.
