We have a client who is running a SBS 2003 server with 4GB Ram.
He noticed the other day that on Disk 1 on the front of the server the lights suddenly were not responding as the other three drives (0, 2, 3).
I opened up the Dell OpenManage software and could see three drives on the connector, I also updated this software too and the same results. Last night I got the client to reboot the server and this morning I checked the event logs to see if there was any disk errors which there was not.
To me it sounds like a dead disk as if the OpenManage software should detect it if it is connected to the controller, but then again event viewer should pick up events from dead disks on boot.
