the RAID controller will support ATA drives or ATA and ATAPI drives.
It depends on which chip that they use for the controller some only support RAID, some only RAID or ATAPI [a BIOS change to select] and some [like my old ASUS] support RAID, ATA and ATAPI.
RTM and look in the BIOS.
What Great guys you lot are helping everyone like this I think its great and I much apreciate the help you lot have given me.
Now with that said my new problem is about hard drives and raid. I have a ABIT KD7 RAID motherboard and I was thinking of setting up a RAID. It states in the Manual that it supports UDMA133 only on the RAID channels. On looking at Hard drives on the web they are mostly ATA133 or Serial ATA or SCSi which the latter I am not interested in. Is ATA133 the same as UDMA133 or not. Also could I just set up a single UDMA133 on the raid channel just to get extra storage or does it have to be a raid with two or more drives. Will a UDMA100 drive work on the UDMA 133 channel or not and would a UDMA133 work on a UDMA100 channel, I realize you would not get the same performance but the final questions are just something that I have been wondering about.
Thanks for all your time and trouble. Kindest Regards Tony B.
