As noted in a previous post, the hard disk in my Sony Vaio notebook is damaged, missing about 25GB.  No problem, I thought. I can replace it.  I found a good, larger drive at a great price on Amazon. It arrived the other day.

I've replaced drives on lots of notebook computers. It was easy.  Well, easy on Dells. On a Dell, you remove two screws, do a little prying, and the drive slides out easily on a shiny tray.  The Sony Vaio was not built to be repaired.
