Summary: I installed the hard drive without a problem using Paragon's Hard Disk Manager to create an image of the old C-Drive. Oh, I used the Apricorn universal hard disk adapter to connect the new drive to the computer as part of transferring an image of my C-drive to it (the new drive).
Summary: It works well for older systems that uses PATA(IDE) interfaces on laptops. I had bought and PATA(IDE) from another vendor which never lasted for more than month for some unknown reason, I could still read the data but couldn't boot.
Summary: Replaced the original Sony VAIO TXN27N CD/DVD drive with this hard drive using the newmodeUS.com Optical Bay Hard Drive Caddy (OBHD9-PATA-B), Black, 9.5mm. I had to file 2 slots on one side to attach the CD/DVD mount to the hard drive caddy.
