Nitpick point - they can, and AFAIK are the only way to verify the  
md5sum of a burned disc.

Interesting though - at least for me, it doesn't always work.
After burning the disk, sometimes using md5sum /dev/scd0 (or using dd  
and piping the output to md5sum) fails with the same I/O error that one  
_always_ gets with ide burning. It's really annoying. For some reason,  
mounting and unmounting the CD usually allows it to verify (with ide- 
scsi) but even then not always.

I'm buying an external SCSI burner soon and will see if that is better.
Since I distribute Linux CDR's I really need a reliable (IE script it  
and know that an error really is an error) way to test the burn after  
the burn. Hopefully going SCSI will do that for me better, and not  
waste so much of my time (I rarely get bad burns, but you just never  
know)
