This is a semi-complete list of weird images in IBM PC set. There are 4 categories:
REDUMP - Titles must be redumped.
TRUSTEDME - Titles with mastering errors coming from trusted dumpers (you know what I mean)
HARD - Weird mastering errors. All share a same pattern so it's very unlikely they are bad (weird track mode byte).
VALID - Images with weird stuff. Proper ones.

The obvious corrupted ones are the ones from REDUMP group.

We need to check for any Mode2 data tracks with 0x55 pattern. CloneCD apparently puts a mode1 byte (01) in the header always.

For this one I put 02: http://redump.org/disc/31914/

There are only those four entries.

Tiger Hunt (Taiwan) was definitely a bad dump, so I changed it to red status. Error sectors were filled with wrong data, and probably there are more readable sectors than what's in the dump.

Formula 1 97 (Europe) (Track 01) has mastering errors at the end of the track. The dump should be correct.

Fritz 7 (Germany) (En,De) image is unavailable and yellow status (should be redumped anyway).

I scanned previous version of Colin McRae Rally (Europe) (En,Fr,De,Es) and it looked fine in cdmage? How do you know it's corrupted?

This game has the same type of protection: http://redump.org/disc/46743/

There are 32 sectors without EDC (so they won't show up on an error scan) that give different results on different drives. So I filled those sectors (32 on both games) with 0x55.

Also, both games have an INDEX 02 on Track 1.
