At what seems to be at random intervals my secondary drive in my workstation just disappears. The OS is not installed on this drive (it's my "E:" drive). I'm not using RAID.
- The PC is a Dell Precision T3500 running Windows 2008 R2.
- It contains a Intel Matrix Storage Controller on the motherboard (v126.96.36.1992). I'm running the windows software for that controller v8.9 (which I guess contains windows drivers - which is why I mention it).
- The failing drive is a Western Digital WD4000AAJS-0 which is a 400 GB 7200 RPM drive SATA (firmware 12.01C01)
I notice system event log entries that seem to correlate to the times the drive goes away: Source isStor, Event ID 9, Description: The device, \Device\Ide\iaStor0, did not respond within the timeout period.
This drive was working fine for more than a year in another PC and was moved to this machine for about 3 months. However, this problem started only a week ago.
Googling for this problem seems to point at the intel matrix controller. Yet none of the workarounds I've found help. (renaming a registry key, updating the matrix software, switching sata ports)
Update The drive started to not just disappear but stay visible and deny access to some files on the drive. I ultimately copied what I could to the working main drive and disconnected it. This workstation's primary drive is too small for the work I do so I'll hook up other drive at some point and post the results here. (Why add 12GB of ram for hosting virtual machines but choose 250GB drives so i have no room for VHDs??)
Also I tracked down to the event log that the problem started the same day I installed Remote Desktop Services role (aka terminal services) in attempt to get Aero glass working over remote desktops to this PC (don't ask). I ended up removing that role since it didn't help. I wonder if some type of power management setting was flipped on/off during the add or remove of that server role?
Update 2 After a few years of running this machine with only one drive (the one dell ships) after never really resolving this issue I ended up installing a second drive again. This drive, a 2012 WD Caviar "black" (WD1002FAEX), seems to be running fine with none of these issues. I assume this issues was caused by bugs in the SATA power management of older drives with this controller/windows 2008.
