You can do it with hdparm. But in current kernels it
should be on by default - if not - there is probably
lack of some driver or it is disabled by parameters like
this. So try to get rid of them.

As it was stated in the first reply by Arjan van de Ven
you definitely should have this disk in sata mode and
see it as sda, so try check in your kernel config
Serial ATA... drivers - particulary:
CONFIG_ATA = y
CONFIG_ATA_PIIX = y
and maybe:
CONFIG_ATA_GENERIC = y
CONFIG_PATA_MPIIX = y

(if they are "= mi", you should have initrd properly generated).

Probably you can also do CONFIG_IDE = n in ATA/ATAPI
(it depends on your CD-DVD).

If you can see it as sda, transfer should be fine.
