Well I was wrong about the hard drives connectors, I was only right about the 4 prong input, the other connector was from other hard drive in my old PC. Dont know if this will help but here are pics of the hard drive. Also the label says its an Enhanced IDE Hard Drive.
I will be able to get the rest of DS9 off this HDD if I can get it open, plus a ton of anime, a ton of DLed games (including DC games). Old pictures/projects. and I cant even remember what all else is on here. Plus what Yukio posted I think will work with my other HDD (which is my actual windows OS HDD) from my old PC which has the Molex wiring, plus the 4 prong one (I was getting that one confused with the one pictured). I can dig out my other hard drive and take pics if it will help. I might as well get something where I can grab files from both since they both have all kinds of stuff on them. Think im gonna go ahead and dig it out anyway. I think the link that yukio posted should work with it.
Only other thing im worried about is since both these hard drives are windows xp compatible, will these USB devices convert everything so it can bee seen on my Mac. There is alot of stuff on these I wont be able to get access to cause its windows specific but videos and pictures and the more general files I will be able to open.
