After successfully testing my drives on a Win7 machine, I put my WD15EARS drives in a Windows Home Server machine.
If you are putting these drives in a Windows Home Server (WHS) you should read this forum post:
And this thread on wegotserved:
These are the guidelines they set up:
- EARS as system drive must not be jumpered but aligned immediately after install (before other EARS drives are attached as data pool drives).
- EARS drives as data pool drives can only be used with jumpers
- Never run WDALIGN on WHS with a jumpered EARS drive as data pool drive.
