got new pc with winxp64 o/s. I would like to transfer my secondary hard drive from old pc (win xp pro)to new. After installing, it is seen in device manager, but no drive letter, it is not seen in my computer. I do not want to format because I want to keep photos etc.(It was slave in old pc) Have been into computer management but can't change drive letter there either. thanks
My self built upgrade to 64bitMoBO/ processor, would not read the original disc and had to be format and reload. Not quite the same as you if I read you correctly you have Win64? You could try putting the drive in a USB/Firewire caddy - both of mine work through this route.
I'm assuming you have entered the BIOS setup and the BIOS has recognised and assigned a drive letter to it? If not, your Windows will not know it's there. If you don't know how to access the BIOS, just ask.
