Hard drive Issues

Thank you all for your answers and i'll try this the first thing tomarrow! And Phillip I currently do not have the hardware to currently put any HDD in a External type enclosure due to money :/

EDIT: Okay so I see inside the MOBO and since theres two SATA controlers and 4 SATA Mem Slots. Im going to have to guess that 1 & 2 are controlled by the first controller and 3 & 4 are controlled by the second controller. So I remember something that I failed to mention before and I forgot too. Sorry. Anyways when I had all HDD's taken out except the SATA, I had the SATA hooked up into slot 1 and booted my PC without going to the main BIOS..Since my PC has multiple Bios's. Theres the main bios for the whole PC and then two mini bios's as I would call them. Theres the American Mega-trend BIOS(Main) and a ALI Raid bios(Second) and some sort of other which I don't remember the name. Ill have to wait to get to you on that third.But it has something to do with the SATA type. Anyways nothing showed up. So I tried the second slot. Still nothing. But when I put it on the third, Instead of a x.x.x.x.x.x as I would normally get with my IDE drives and my IDE drives with the SATA hooked up on 3 & 4, I got a x.x.x.x.o.x And the third BIOS noticed the SATA drive and put it on 3rd Channel Master. And It won't let me boot from my IDE it'll try to boot from the SATA..Which has vista on it BTW and I want to format it as the CD's are lost and the PC it was in no longer functions. And the same happend on the fourth slot except it put it on Channel 4 Master and said x.x.x.x.x.o...So i'll have to look further into that. Currently no matter what I did it woulden't show up in my main BIOS. I set the PC to RAID and tried it and it still didn't pop up yet it tried to boot from it. And then I set the BIOS to SATA and it wouldn't show up in BIOS either. But when I didn't go to main bios it skipped the second bios and went straight to the third and attempted to boot from the CD and it worked. But it said there are no drives installed...So Please help if you kindly can. Ill do whatever I need to do thats necessary to get this drive working. Have a nice night!
