I have a Toshiba Laptop (Satellite 2805) for which I just purchased a new 12 gig Toshiba hdd. I installed the hard drive, physically but when I went to format the drive the system told me that no drive was present. I thought that the problem might be linked to the computer itself, so I purchased a hdd converter and tried to load thr drive on my desktop, however my desktop did not recognize the hdd as well. Both systems told me that the hdd was malfunctioning, not present, or in need of drivers???? Is there something that I can do to solve this problem? Am I doing something wrong? Has anyone else experienced a similar problem? Much thanks for any help.
