Cayenne - I used 160MB Maxtor drives in my upgraded 4100.

As I mentioned, did you consider upgrading the RAM? I believe you will have better luck with the server using these larger drives, if you upgrade the RAM.

I did not have any problem using the larger drives. They format automatically to around 128MB - this is due to limitations in the 4100, you will not be able to use the full 160MB but again, I have done this and it worked, that was not a problem.

I had error messages in my logs very similar to yours.

Snap-tech (one of the power users around here, and former snap technician) was very helpful to me. He was the one that suggested taking the cover off to allow for more cooling while building the RAID.

I would also switch the drives around - or switch the cables, format again, and try to rebuild the raid. Then you could see if the error message indicated a different drive.

I have NEVER seen these messages in my log files, it must be coming from the 4.0 OS, I am still on some version of 3.x

IDE: A 48 bit LBA capable Hard Drive was detected ...
IDE: 48 bit LBA is not supported on 4100 and 12000 platforms.

I still do not think that is of any concern or cause of your problem.
