Regular reader will recall that I modified my MacBook Pro a few months ago and fitted an SSD.
I got itchy fingers again and I had the laptop in bits, this time to remove the stupid optical drive and to replace it with a standard hard drive. I now have 128 G SSD and a 160 G spindle drive.
The SSD is perfect for the OS and apps, it makes the machine uber fast. The spindle drive is more suited to my iTunes library and photographs.
The loss of the optical drive is irrelevant to me, I hardly ever use it. I can use the optical drive on another Mac or Windows computer on my network, plus I do have a USB DVD drive that I can use.
The original plan was to remove the optical drive, bodge up a cable to go from the very proprietary Apple connector onto my SATA hard drive, and fix the drive in place with a hot glue gun.
However I discovered that purpose built caddies are available to fit the MacBook that take an HDD and are pin for pin replacement of the slot optical drive. Not as much fun as hacking but probably a better, more elegant solution.
The optical is a so and so to remove, being buried under cables, Bluetooth and WiFi aerials and sundry other ‘stuff’. Once out it is relatively simple to put the HDD in the caddy, it just clips in place, and then reverse the disassembly process.
I was mightily relieved when the MacBook passed it’s POST with the customary ‘bong’ and the two drives appeared on the desktop.
This is a serious mod, not for the feint of heart or those concerned about warranty. It is completely reversible if needed. It took me about an hour to complete. Small pozi and torx drivers are required plus tweezers and needle nosed pliers. Static mat is a good precaution. I photographed the items as I removed them as a aide memoir when reassembling.
(This was easier than disassembling an iMac to clean out the fans of cat hair.)
