BIOS not recognizing hard drives (SOLVED)

Specs: Windows 7
I wanted to post this to another thread on here as a reference , but it wont allow new posts, so I make a new thread here in case people search for it and can use the info:

Anyway, had a similar problem as in the other thread, none of hard disk drives showing up in BIOS, but DVD drive did. Turned out to be the disks. All of them at the same time had been fried!

I knew the disks were ok as they were in daily use and I was swapping them to a new used machine I'd just bought, so at first I read the original thread and thought the motherboard as well.

But just to make sure it wasn't a faulty PSU, I took one of the SATA cables and connected it to a disk inside another computer that was obviously running on its own PSU, and it showed up!

Testing that disk inside the problem machine, it showed up fine, so unbelievably the 3 disks had somehow been zapped during installation! How about that for the books!

They must have been fried during installation as there was a point where one of the disks had a loose power cable and I pushed it in while the system was running (booting), and I now believe I heard an 'electric' sound in that moment. As they were all on the same power line something must have happened.
