Thanks!
It works fine.
However, I also have the desire to monitor Physical disks, and to report the info trough email....
Here's my modified version (please, be kind... it's my first time ever with PS script).
Note that I pipe DiskPart for disk status instead of "Get-Physicaldisk". I currently have a drive in error, Diskpart flags it, Get-Physicaldisk doesn't.
