Well, it's a week later and I've been trying some things. I don't want to get in to too much complicated detail, but I've now got the following disk setup: Primary Master - 200GB 7200RPM Secondary Master - TDK VeloCD CD Burner Secondary Slave - Sony DRU500A RAID0 Master - 160GB 7200RPM RAID0 Slave - 160GB 7200RPM I don't have the two 80GB's or 60GB's in there now since I was just testing with this setup. I thought keeping the OS drive on primary master and the rest on RAID would do the trick, but it didn't. Bottom line is, I'm still getting the same errors with several different configurations of the drives. Now in the last couple of days I'm also getting READ DMA errors when reading from one of the 160GB drives as well. Before it was all just WRITE, but now some READs are thrown in there as well. I should note that I have never seen a "FAILURE" message, only the "WARNING" messages. Also, if I downgrade the speed to UDMA100, it seems to work just fine as it does in UDMA66 mode. I'm wondering if anyone else has any ideas? Personally I'm out, and if nobody else knows (including Maxtor, Giga-Byte, and my parts distributor) then I'm going to have to see what I can do to get another brand/model motherboard. I'm to the point where I think it's something with their controller and how it handles Maxtor drives. Now that I remember, I used to see similar results when running Windows on the previous board before sending it in (same model). However Windows would automatically take it down to 100 so I didn't see any errors. Anyone think its something other than the board and it's controllers, or is that a pretty good estimate? Thanks in advance. -Mark Mark Kane wrote: > Okay well I tried another test.
