I have got this laptop..
Could someone please gives me a head up of how to downgrade this laptop from Vista to XP Pro?
It seemed like the HDD is locked to the system ... (XP Setup disc returned error "Setup did not find ay hard disk drives installed in your computer")
I know this is a little technical but Please help!

I'd bet on the HD Controller not being supported natively in XP - therefore, you'll need to check the Toshiba drivers support pages and see if you can download it. Then when installing XP you're asked to press F6 to install any third party drivers? This is where you'll need it.

Where can I download the HD Controller software ?

Like I said, check the Toshiba website and see if they are hosting the HDD controller drivers.

XP does not support sata drives by default, If you go into the bios and find the HD controller, there should be an option for "compatability mode" or "AHCI" , choose compatability mode, this will now allow XP to load and after changing it back to AHCI, XP will discover the SATA drive.
Hope this helps.

This isn't a blanket thing and AHCI is a totally different type of SATA driver. Installing an OS using std SATA BIOS settings and then switching to AHCI will result in it not booting (in most cases). Plenty of people have managed to install XP on SATA HDDs without any bother - it all depends if your controller is listed in the XP HCL for whatever release you're using.

That's what I did when I tried XP on my laptop. XP setup sees the drive as in IDE device at the bios level so no sodding about downloading redundant drivers.
