Build
What runtime version are you using?

  • .NET 8.0 running on (Operating System)

Describe the issue
Attempt to detect media type for a very small UDF DVD-ROM (164MB) incorrectly detects the disc as a CD-ROM.

Scanning for drives..
Found 2 drives: E:\, F:\
Trying to detect system for drive F:\.. unable to detect.
Trying to detect media type for drive F:\ [UDF] using size and filesystem.. Detected CD-ROM.
Supported media speeds: 1, 2, 3, 4, 6, 8, 12, 16, 20, 24, 32, 40, 44, 48, 52, 56, 72
Setting drive speed to: 16
Local version: 3.2.0
Remote version: 3.2.0
You have the newest version!

An attempt to dump with redumper (without changing media type) will result in a successful dump but cause the process to fail at protection scan/info gathering. DIC will refuse to dump due to being passed the wrong media type.

To Reproduce
Steps to reproduce the behavior:

  1. Insert a sufficiently small DVD-ROM with a UDF filesystem
  2. Click "Scan for discs"
  3. Check to see which media type has been detected

Expected behavior

The disc to be detected as a DVD-ROM

Additional context
The disc in question is Side A of the first disc of Cartoon Network Power Pack, consisting of two double-sided discs, each with a DVD-Video and a DVD-ROM side (https://www.ebay.co.uk/itm/195943982458)
