Comment 60 for bug 15424

I am also having this problem on hardy.
Other interesting related facts on upgrading from gutsy to hardy:
Mount changes (gutsy -> hardy):
/dev/hdb1 -> /dev/sdb1

So it seems like the scsi/ata driver has taken over all of my IDE devices.

I am on an nvidia4 chipset, with an old HP 9300+ CDRW drive

output from "wodim -blank=fast -dev=/dev/scd1":

I also have tried adding "combined_mode=libata" to my kernel params and adding a new file to /etc/modprobe.d with this line in it:
options libata atapi_enabled=1

Neither have helped.

My linux HD is a SATA2 drive with NCQ enabled, not sure if that makes any difference.
