LAPTOP hard drive that can also be installed in a DESKTOP computer. 320GB with Windows 10 and MS Office 2K installed, tested and updated. Shipping only $4. Also you can have a drive with Linux or formated drive without an OS. Some drives came out of Apple computers, i did not format them, they may have an OS and other programs on them, but I am not sure, because I do not have an apple laptop to try them. If this is what you are looking for, I can send you one un-formatted drivee, and it does not have software, you cannot return it for this reason.
