According to an comment in the /etc/rc.d/rcsysinit it does not : .... # Turn off DMA on CD-ROMs. It more often than not causes problems. ..... The solution seems to be this : ..... # Turn on harddisk optimization # There is only one file /etc/sysconfig/harddisks for all disks # after installing the hdparm-RPM. If you need different hdparm parameters # for each of your disks, copy /etc/sysconfig/harddisks to # /etc/sysconfig/harddiskhda (hdb, hdc...) and modify it. # Each disk which has no special parameters will use the defaults. # Each non-disk which has no special parameters will be ignored. # ....
