Well I got my hard drive as expected today. Unpacked it carefully, removed my secondary harddrive (Seagate) and installed the new one (in slave position as I want to clone it later with Clone 2003). Booted my PC.
Got this instead:
The new drive is dying faster than my three year old drive, which it (the new one) was supposed to replace! Numerous utilities later and a 2 hour failed attempt at cloning, I believe it is fair to say that I received a dud Maxtor.
E-mailed Overclock. Let's see what they think about it.
Update: Well my RMA request has been authorised. Will send it back tomorrow.
