PowerEdge 2450 Hard Drive Problem

I've got multiple PowerEdge 2450 servers with (4) 1" drive bays. When trying to use all 4 drives on either of my Windows 2003 servers it only sees 2 disks. When looking at the Device Manager it shows that there is a problem with the Secondary IDE Channel stating that "This device cannot find enough free resources that it can use"

I believe that the problem is being generated by IRQ 15 which is being used by the System board. Has anyone else experienced this problem, and or have a suggested fix (Other than trying another IRQ range)

Thinking about it more... The hard drives are SCSI, so an IDE conflict wouldn't affect them, correct?

They are physical disks. There are 4x17GB SCSI hot plug disks. It's a 1U server, and the 2 disks on the left work, while the 2 on the right are not recognized. There is a raid controller installed on the machine but it is not in use.

Are these physical or logical disks? Are you using a Raid controller at all.

As far as the secondary IDE, you probably haven't got anything installed on it or have you?

Sounds like you have a split backplane and only one channel connected.

Try removing all the drives and have a peak in to where the drives sit on the BP.

You may see a daughter card. This splits the BP. Remove if it is there and the BP

should then run off the one channel.
