Recently I upgraded the HD in my laptop to a SSD with twice the capacity. I cloned the old drive onto the SSD and everything is as it was, only a lot faster. Now I want to use my old laptop HD to clone the system drive of another computer as a backup. I have the old laptop HD in an enclosure and the device manager, connected devices in settings, and safe removal icon in task manager show the device as being present, with no errors. However, in Windows Explorer, the drive doesn't appear and when I look for it under Computer Management>Disk Management, there is one drive that isn't initialized and the Virtual Disk Manager returns the following error when I try to initialize it: "The device is not ready." It's possible that the uninitialized drive isn't the laptop HD, but without the ability to check the contents of either, it's impossible to say. All I want to do is format the drive so I can use it to clone a backup. Does anyone know what's wrong?
