SlimLine Optical Drives Compatibility PC/MAC
Size:
Slim line optical size are always 12.7mm height, just recently some manufactures
released SuperSlim 9.5mm height "thickness." Although small, these
lack in performance.
Physical Dimension:
One simple answer: they are all the same. Manufacturer's follow set standards
just like hard drives. If your system uses slim 12.7mm drives like the images
below, then it will fit.
Some OEMs like DELL and HP use a shell case that envelops the CD or DVD drive.
In this case one must remove the old drive from the shell case and replace /
upgrade the internal bare drive. Bare drive without shell casing, rail, or adapter
will always look like this......

Bezel/Front
plate:
Dell and HP often use their own stylish bezel. A generic black bezel such as
the one in this picture may not match the color or shape of your system. Apple
uses slot load slim drive and place their drive inside the computer eliminating
the need for a front bezel completely.
Compatibility:
Like hard drives, Slim CD/DVD must be set to ether slave or master. Because
there is no jumper on the drive to change one to another it is important to
know if your system requires the drive to be set as a Master. Apple and a few
Toshiba systems require Master drives, however most use Cable Select-Slave /
Master. Typically the drive is set to master or slave by the system cable configuration.
If the optical drive is not configured properly, it will not be detected by
the BIOS or you will get IDE #1 error when you start the system.
