Windows can't find my second HDD

[flysky1000]

Hi guys!
I have a problem with my PC.(im form Latvia and my Win7 language is Russian so sorry if i do some mistakes, because I have to translate)
Some time ago, when i was starting my pc it was checking the disc (H) for errors. And it happened every time i started my PC and it freezed every time the checking was ended. So I tried to format the disk and Windows didn't allow me to do that.
Today i turned my PC on, it was loading very very slowly and when it turned on the disk disappeared. All the parts of my 1.5tb disk (i had 3 toms) disappeared. I couldn't find them in Computer Managementor anywhere. But the HDD was shown in BIOS and it was warm.
Now Ive disconnected my second HDD from PC, but if you have got ideas to repair it ill connect it.
Sorry about my terrible English. Im just studying.
Thanks alot!

run some drive fitness tools from the cd and an anti virus sweep. with hard drives it can be the drive or the mb chipset that could have gone bad. i would see if the drive is found in another pc.
