Hard Drive 1 is the C drive from my old computer.
Hard Drive 2 is the D drive from my old computer.
Hard Drive 3 is the C drive on my new computer.
I started out with HD3 and HD1 in my computer. 3 as the C drive, 1 as the D. It worked fine, aside from the fact that SMART disk was always telling me that HD1 is basically dead.
So I transferred everything off of HD1 onto HD3, and switched HD1 for HD2. My computer started up fine, when I opened windows it found the drive, loaded it, everything looked like it was working. But when I go to My Computer, I see only the C drive. I went to Add New Hardware - both HD3 and HD2 are loaded, and supposedly working properly. SiSoftware System Analyses found both hard drives, says they are both working properly.
So I went to Disk Manager, and even there, it shows both hard drives... and at the same time, doesn't.
