I have had to replace a computer that had a defective motherboard with a new computer. I have taken the only HDD out of the old PC (windows XP) and I made it the slave HDD in the new comptuer (also XP)to copy some data from old to new. After booting up, the new computer recognizes the old HDD as slave in CMOS and displays it in Disk Management but whithout a drive letter. I have tried rescanning and all other functions are greyed out except “delete partition”. Old HDD is a 40 gig Maxtor Fireball 3 IDE. I have tried slaving this drive in several PC’s to make sure it wasn’t the new comptuer and get the same result. Is this a new security thing with windows XP? Does the Maxtor drive need specific drivers installed? I remember the old days when you could slave a drive and copy what you wanted. How can I get the new computer to give the slave drive a drive letter whithout having to delete partition and format?
