i have a 120gb WD 2mb cache drive, it has recently started to make a noise so i know i need to call WD about this but waiting until i have the money for the advanced RMA. Tonight i ran the datalifeguard on the drive and it said everything was running fine. Is it normal for that to report fine even if its clicking. The other thing is i went to work and came back and the drive was missing from windows so i rebooted and bios hung on ide scan, rebooted a few more times before power down then back up. After power cycle is worked. Can anybody give me an idea as to why windows "lost" the drive for a bit, im just lost myself as to why this happened
