After having a few tablets, I decided to rather try a PC/Tablet and, as they are cheap second hand, why not. I got a nice second hand machine running a fresh install of XP off the local Auction site. I have a spare PC with XP and all my packages and personal setting loaded. I use Snapdisk to copy the XP to any new machine I have. I restored to the TC4200 and then tried to boot. 'A disk read error occurred. ' I assumed it hadn't worked correctly. Tried again, same problem. By chance I took the drive out and put it into my Toshiba Laptop and switched it on. Next thing I know is everything loaded and working as per normal. Windows and programs all there and working. Put it back onto the TC4200- Same error. A disk read error occurred. Ran BART. C: drive all intact with all my programs. Is this a bios fault and how do I get around it.
