As long as the hard drive is in good shape, then of course you can. You should note, however, that it's probably going to be a slow hard drive - as long as you have an SSD boot drive and are only using the hard drive for data storage, you'll be good, but if you're using that hard drive as a boot drive, it'll be very slow.
