Thanks for the quick response. I recently updated the BIOS and firmware on this system to the latest versions in advance of installing VMware ESX5i. Everything went smoothly and I've had virtual machines running for about two weeks. In the past couple of days I had drive 0 start flashing amber. Before I could order a replacement, Drive 1 failed. I suspected that my updating the PERC firmware caused some sort of problems with the drives. Was this just bad luck on my part? 
I have a question about a specific drive when running Nautilus.When running Nautilus from a 2950 w/Perc5i. The utility correctly identifies several drives and tests them as Seagate ST9146802SS. When running Update against the drives, it will only test them, and won't update them. The drives are currently on FW S20C. Nautilus A44 includes a readme that covers the following two firmware updates for this drive: 18.0 Seagate SAS 2.5", 10K, offline download version S20C, for drive models ST9146802SS and ST973402SS23.0 Seagate 10k SAS 2.5", version S22F for drive models ST9146802SS (146GB) and ST973402SS (73GB) This machine is running Vmware and Nautilus seems like it's the only tool capable of installing the newer firmware on these drives. How do I update to S22F? Thanks for your help, Mark
