Some have claimed this can happen if you: a] Plug the cable in backwards - ie., the end with the single plug should go into the motherboard and the end that has the two plugs closer together should go into the drives. b] Plug the wrong one of the two that are closer together into the driver. So I'd say try pulling out the cable and plugging it back in in a different way. Another thing to be sure of is that you have the UDMA 100 cable; ie, one end should have a blue connector and that end should go into the motherboard. -- Jonathan Arnold (mailto:jdarnold@buddydog.org) Daemon Dancing in the Dark, a FreeBSD weblog: http://freebsd.amazingdev.com/blog/
