I am a computer tech, and have run my company for 10 years now. I have generally recovered data from drives that had errors other than the physical - formatted drive, corrupted tables, etc, but I send off more damaged drives to a professional place that costs $1200. Today I have a drive that is not really of high value, so i decided to try to do further recovery, just to see how hard it is. Of course, it's harder than I hoped.
The drive is clicking at spin-up, and then powering down. I was optimistic when I saw some videos that I could pull off the cover and find a head stuck to the platter, fix it, and be golden. Opened it, but the head was not stuck. Strike one. Option two was the logic board. I happened to have a matching board on another old drive, so I swapped them which was amazingly easy, and fired it up. Strike two. So now I'm out of options as far as I can see it. I did fire up the drive with the cover off (I know that's not a great idea, but how else can you get into on what's really wrong?) and took a video. You can see what it's doing here:

Any suggestions are appreciated. Thanks!
