If it's 2TB, I bet it is. However, I haven't had a problem with those drives under Vista or Win2k8.
For me, they "worked", but I was using them as video server drives, and had stuttering, bad file copies, just strange behavior. Sometimes they worked .... sometimes they didn't
Looked up his drive on newegg (well with the limited info, no model number) and lots of RMAs, lots of no worky
