I used the Hard Disk Migration wizard to change to a bigger hard drive (actually did this twice). Now, when I try to use the old hard drive(s), they don't show up in My Computer, in Disk Management it shows as offline and unallocated (even on other computers). If I 'get to' the drive, I can't format it, keep getting a write protect error, even on a Mac. All I want to do is utilize the space on these two drives again. I do not need to save anything, just format and start using the drives again. Can anybody offer assistance? Thanks!!! I've tried hooking the two drives up via esata and usb, no luck with either.
