I recently bought a new SATA hdd and since my motherboard does not support SATA I bought an RPC partable 3.5". I formated the hdd, waited 6 hours 4 it, with a program that was on a cd that came with the RPC, but it still won't show in My Computer, only in the disk management, where I pressed " initiate the drive" and now it reads Disk 1 basic 465.76 GB Online "unallocated".
I'm out of ideas

, just please don't say that it won't recognise it because my desktop doesn't have SATA cables

thank you
