I did some more testing. At least in WinUAE (A3000, SCSI CD drive), NetBSD
2.1 doesn't have that problem. It reads all 19057 sectors from the disc.
And the same with NetBSD 1.6.2 with emulated A4000 and ATAPI CD drive.
So this issue could possibly be a regression in later NetBSD versions. Or
it could be an emulation bug if earlier versions somehow accessed CDs
