Thanks guys, yeah, i thought it might have been a HD error, but the chkdsk came back clean.

I didnt want to a repair install or put old files back on... too many patches to re-apply

So besides that, is the installation is toasted??

LOL... well, that installation had been running for 2 years, so i guess it was time to do a format anyway.

I've never seen this error before, its just amazing how random certain things are! You must be lucky or Unlucky, to get a combination of hardware that causes problems.

Cheers.
