I have a Toshiba Satellite A205-S5000 with Vista home on it and it works OK, but I bought a larger HDD and I thought that I would put Windows XP PRO on it, I went from a Hitachi 160GB 2.5" SATA drive to a 250GB drive, same Manufacturer, the only difference in the drives is the original was a SATA 1.50 and the new drive is a 3.0, BIOS see's the drive and the XP disk does al the usual stuff, then it asks if you want to Install windows on it, so I click OK and then it says the windows cannot detect any HDD and aborts the installation, I know that the 2 SATA's are compatible and the only draw back is that the 3.0 may operate in the 1.5 mode in the worse case scenario, but windows doesn't see the drive at all, any help or idea's would be appreciated
