I bought a 1TB Samsung Spinpoint F3 HD103SJ like 7 months ago. I started getting a "Windows Detected a Hard Disk Problem" error about a month ago. It popped up about every 15 min-1/2 hour. After searching the net and finding nothing I decided to RMA the drive. I got my replacement, cloned the old drive to the new one, and it was fine for about a day and now I'm getting the stupid message again. I was on Windows 7 Ultimate X64 SP1 beta, so I uninstalled the SP1 beta, and the IE9 beta thinking that might help. It didn't. Could Windows be thinking that it is still the same drive and I have to replace it, I mean do I need to clear the error info. for the old drive or something? I've scanned both drives with Seatools, Samsung's HUTIL, and checked the drives for errors with Windows and they seem to be fine. The only strange thing I found was when I used the in depth online analysis in speedfan on the first drive it said the throughput performance was below the threshold defined by the manufacturer. Everything is fine on the new drive. I know there are always defective electronics, I'm just skeptical that I got 2 bad drives in a row.
