SATA Hard drive on old PC

The old 40GB hard drive died on my Fujitsu Siemens XP Pro desktop PC. I ordered a new Hitachi 320GB drive, unaware that the communications standard had changed from parallel to serial i.e SATA. The power supply plugs have also changed and I understand there is now an additional voltage required. Will I be able to use the new drive on the old machine or would I be better to start from scratch and build a whole new computer? I see I can get a PCI 1x IDE & 2x SATA RAID Controller. I don't know if that's what I need but in any case, that won't solve the power supply issue.

 

One of these will solve your power problem.

look on ebay you can find sata to ide adapters really cheap, it plugs into the back of the hard drive and u just plug ur IDE cable into it

 

Thanks for the replies. I was not sure if these cards were designed for connecting an old drive to a new PC or vice versa. Perhaps they can work either way?
I did see this one but was just not sure if it's what I need:

this is what im talking about. this plugs into the back of your new sata hard drive then you just hook power cable and ide cable to it, its pretty easy and they are cheap

I actually ordered this one but I'm still not sure if it will work:

If it plugs into the motherboard instead of the normal ribbon cable I will lose the IDE connections for the existing DVD drives.

 

thats more for turning a IDE drive into a sata drive and you normally have 2 IDE channels on older motherboards but that adapter should work. but u wont be able to plug in anything else on that IDE channel

 

The bits came and I connected it up this evening. I had forgotten, the DVD drives are on a different cable so I can manage like this on a temporary basis. I have another hard drive that was previously used for backing up files and I want that in as a slave at some point so I will need an extra parallel connection.
It seemed to be working OK with the XP recovery disc. It formatted the hard disc and was then loading files but must have crashed part way through. Now when it tries to boot it comes up with "disc read error". If I try to boot with the CD it just crashes. :cry
