In my BIOS,I have only 2 options for hard disks..enable SATA as RAID or enable SATA as IDE.By default it has selected "enable SATA as IDE".But UDMA is set to UDMA5 by default and not UDMA6.I have to manually set it to UDMA6 but still hdparm shows it as UDMA5.Do I need a reinstall of F7 with UDMA6 set???? <div>On 9/13/07, Mikkel L.

It primarily a tool for PATA drives, with some use with SCSI and SATA drives. There is a sdparm program, but it is not that easy a program to use. That being said, in most cases you will find that the BIOS has already set the transfer mode to the fastest supported. You should be careful about changing the setting with SATA drives unless you are sure you know what you are doing. (You should also be careful about what you change on PATA drives.)
