Ok, I test on raw atapi and scsi on my test machine. Also SMP.
All the data or some of it? Could I get you to find out where the corruption is taking place -- try doing a cmp of some corrupted files and the originals, to see where the offset is.
[root@pepsi cd2]# cmp ~adam/ncd19r.tar.gz ncd19r.tar.gz /home/adam/ncd19r.tar.gz ncd19r.tar.gz differ: char 956417, line 2467
Same deal, corruption starts at the beginning of a new 2k sized buffer.
Could you read the first 2048 bytes from the CD-ROM file and check that
this buffer is zero? It is here, which means that a gather-block wasn't
brought properly into memory before being written out.
