"99.9% of raid problems come from user error not the controller."
I guess I fall in the other .1% as the highpoint controller on my KT7 is completely worthless. It literally doesn't do anything. I had 4 identical WD drives and did some experimenting with them and the onboard RAID controller and never got anything to work. My original intention was to run the 4 drives in a RAID 0 + 1 array. I went through the BIOS menus and tried to set one up. All four drives were detected properly yet whenever I selected 0 + 1 it told me I didn't have enough drives. Huh? Things only got worse from there. I tried setting up a stripe using 4, 3, and 2 drives which would setup properly, then would try to format the array and nothing would do it. DOS, win2k diskmanager, win98, partitionmagic all locked during attempted formats. After giving up on RAID, I just tried hooking a single drive to the controller to see what the result would be and the thing was seriously screwed up. In win2k it brought my whole system to an absolute crawl even when I wasn't accessing the drive. I don't know if there is an incompatability between the controller and WD drives, but I was underwhelmed to say the least. The WD drives are all fine as I was able to set up a 4 drive software stripe in win2k using a Promise ATA 100 controller without a hitch.
