Doh I thought I posted something yesterday but I guess I must of messed up.

Thanks Tumbleweed for the quick reply. I did check raid was not on as well as the boot priority.

I had a go at putting the suspect HD into the computer and held it. It span up and made this high pitched noise. I admit I have heard the noise before in my pc but it was breif and I thought it was a variation on the motherboard beep startup. Also after this noise there were no issues. So I just left it.
I did the same thing for the old ATA hard drive. Plugged it in and held it in my hand and it sounded more lively. Span up, loads of clicking. On startup I got a new mesage. Instead of 'BOOT DISK FAILURE' I get a lovely 'ERROR LOADING OS'. Thats because there is none on that HD :)
Installed windows fine and I will get a new SATA hard drive in today and in a few weeks I will probably have the dead SATA replacement as well.

What I wanted to ask before this is classed as SOLVED was regarding ATA.
After a bit of researching I find out that SATA has a supior data transfer rate. But does this effect me a lot of windows is installed on an ATA and all programs and data is saved on SATA? Will I notice much difference if my OS is installed on a SATA drive over an ancient ATA?
I ask this because i have installed my OS and all the drivers and I really dont want to reinstall it onto a new HD unless I really have to.

Many thanks
