lots of c2scan errors without ide-scsi

[Christoph Heine <deb-cdwrite@hal9000.HaDiKo.DE>]

Hello,

Without ide-scsi, the command "readcd dev=ATA:1,1,0 -c2scan" (executed
as root)
shows a lot of C2 errors:

C2 errors total: 172300868 bytes in 172643 sectors on disk
C2 errors rate: 22.549966% 
C2 errors on worst sector: 1999, sectors with 100+ C2 errors: 172585

With ide-scsi, readcd dev=0,0,0 -c2scan reports no C2 errors. 

Is this a bug in the kernel or in readcd? 

I'm using Debian unstable, readcd from the cdrecord 2.0+a38-1 package,
kernel 2.6.8.1, and a Plextor PX-W1210A with firmware 1.10.
