Hi, Last night I downloaded the free version of true image and set about making a clone of my primary 70GB Maxtor IDE disk onto a new 120Gb Maxtor sata disk and setting that up as a my new primary drive. After installing the drivers and ensuring my SATA Devices were enabled, I used Acronis' True Image CLone Disk to copy and set up new new disk. I hadn't presented the disk yet but was able to choose the new disk and the copy went fine with everything seeming to go according to plan. After it completed, I changed the boot path to look at this new drive and completely ignore my old IDE drive. XP came up fine and new system hard drive was F:. The old c:drive is still there but according to disk manager, it isn't the system disk. However, when I unplugg my old disk, XP won't load and just sits there on the Blue XP Logo screen. I think I just need to go into disk manager & rename the c:\ Drive and as Z:\ and then rename F:\ as C: but thought I'd ask you chaps before I went and did anything I regretted. If this works I think I'll have to buy true image as that is too easy !
