I greatly appreciate a response! First one too!
I posted another post in that thread linked above, with an update:
Bit of an update, when I disconnected the SATA cable for the new HDD, the computer booted and ran fine (and so did Rainmeter). So I tried reconnecting it. Stupidly, I had set up a super-long check disk run, which I left on over night (of my primary drive). It booted fast up up to the disk check (and then I went to sleep because it took an eternity - but no errors had appeared by the time I slept), and I just logged into Windows now - Rainmeter is again failing and the new HDD appears as unformatted, without the "fill bar" under it in "Computer."
I tried running Recuva on both drives - it found most of the stuff from the new drive, but said it would take two days to recover! That's a bit long - I can probably just copy over the movies from my roommates HDD, and get the ones he didn't have on there from my HTPC, via my laptop, when I go home for the weekend next - much less of a hassle, when Recuva might not even do a good job.
So now I'm at a loss - do you guys think the new HDD is bad? Should I reformat and try again? Why the hell did it freeze up in the first place and then cause these problems?
Again...any help would be much appreciated!
Recuva basically failed to find anything on the first HDD anyways - many of the videos were over 10 GB and didn't go to the recycling bin even.
