With Apprentice format in DA, sean_sk's Track 6 dump only has 2 unformatted tracks, 58.1 and 61.0.

Yep. Unfortunately I don't think the data tracks are being correctly detected using that format so I think it is unable to identify the damaged tracks properly. Those damaged disk tracks are responsible for 3 of the 6 race tracks (2-4) on the disk to not load properly in-game. So even when an IPF is created using the Apprentice format the same problem exhibits itself because the same disk tracks are still damaged.

They seems to be damaged. There is something wrong on those tracks, but i'm unable to determine what the problem is.

I'll take a closer look at the datadisk, track 5 and 6, maybe the track loader is different. The acid format works fine with the standard Super Skidmarks (7 disks), but fails on the 2 extra track disks I was surprised the Apprentice decoder worked at all as the track length is slightly longer than the acid format and the checksum calculation is slightly different.

I have another copy of the data disk and track disks and track disk 5 decodes all but T0.0-0.1: Unformatted*. Track disk 6 fails completely, but if I use Apprentice format it does decode the first 34 tracks.

Yeah I think this is fairly typical of Track Disk 5. Mine does it and so does the Powercopy version available on the EAB FTP server.
