What should I know before replacing the optical drive of my notebook computer?

Before you upgrade or replace the DVD/CD-RW drive in your notebook, make sure that the drive you are buying is compatible with your computer. Some notebooks require an optical drive that works in cable select mode (CSEL). Some notebooks require master/slave (M/S) drives. Typically the drive is set to master or slave through a firmware flash. If the optical drive is not configured properly, it might not be detected by the BIOS or you will get error when you start up the laptop.

In most cases you would be able to use the same connector board and DVD drive caddy (braces) from your old device. Just remove them from your old drive and install on a new drive.

Also make sure that your current plastic bezel (front panel) will fit a new optical drive. All bezels are different and very often you have to have a specific bezel for a specific drive. Do not hesitate to contact the seller and ask about the drive and the bezel compatibility.
