I thought I was having the only issue with this drive. I got this error message when I first installed the drive.

I RMA'ed it to Samsung (took about 1 month to get a replacement which they gave me a refurb with different serial #) and it still shows the same error when I first put it in. I ran the WD Lifeguard extended which passed.
Not sure if this drive was designed differently that Windows 7 thinks its going bad, or if I'm just unlucky twice in a row.
