We are running OS X 10.4 on our sever with an additional Maxtor 250GB drive and today it started slowly saying server connection problems and ultimately disappeared and are now unable to mount that drive. Tried using Disk Utility to repair the drive and it will not mount the drive. Just downloaded the Norton Utilities upgrade, ran the program and it mounts but am afraid to reboot with the consequence of losing data. Should I reboot, what else can we do?
