I recently bought a Western Digital 2 TB Caviar Green SATA Intellipower 64 MB Cache Bulk/OEM Desktop Hard Drive WD20EARS and added it to my Windows Home Server (WHS).
I did not realize that I needed to do anything special to my new Advanced Format drive to add it to my WHS – but soon witnessed some odd behavior after installing it.
My nightly backups started to fail and my nightly backup to the cloud hung. In the morning none of my clients were able to access any shared folders. Rebooting seemed to resolve the issue (until the next morning). I soon found the following error in Event Viewer:
Event ID: 11 The driver detected a controller error on \Device\Harddisk2
Disk Management confirmed that my 2TB drive was \Device\Harddisk2 and so I tried to remove the drive from the pool. The process for removing the drive hung – but I still waited for 24 hours just in case. At that point I discovered that the Event ID 11 error had occurred shortly after the drive removal process had begun.
The only course of action left was to shutdown my WHS and just remove the drive. I then booted WHS and removed the missing drive from the storage pool. The next step was to fix the drive – fortunately I had a spare hard drive jumper lying around and easily found the correct setting on the Western Digital site:
All that was left to do was shutdown the server again and put the drive back in and re-add it to the storage pool. I have copied to the drive and found no more errors in Event Viewer.
While this will not be an issue in the next iteration of WHS (Vail) it is surely a mistake that I won’t make again!
