Is this drive IDE or SATA? Internal or external? The term slave was used with IDE drives where you had two drives on a single cable, but modern computers use SATA where this concept is obsolete, since each drive has its own data cable. Do you by chance refer to where the BCD is stored?
How do I slave a hard drive on my Windows 8 Computer?
I had the hard drive slaved to my xp and it was fine, I plug it in to Windows 8 and it doesn't recognize it. Plug it back into the XP and it shows up fine. I'm not really experienced with this, I'm used to just hooking the hard drive up and booting up with XPs and it knows there's another HD available for storage, is the process different with windows 8? is there something specific I need to do to get it to recognize the HD?
