MBP Optical Drive Replacement
Image by Manuel W.
The DVD drive in my 2007 MacBook Pro died years ago and I don’t miss it one bit. I replaced it with a 500GB hard drive by using an Optical Bay SATA Hard Drive Enclosure from iFixit.
The 500GB hard drive is on the right, a Western Digital Scorpio Black. On the left is my boot drive, a 120GB 3G Solid State Drive from OWC. I use the big drive for archive/overflow storage, old photos, videos, etc.
The SSD hard drive is FAST — it breathed new life into this 4 year-old Mac, which was the goal. Now I can keep all my files under one roof without relying on external storage.
* Update: I added a script which unmounts the big drive every time the computer starts up. This spins down the drive which prevents it from drawing power and generating heat and noise. The Applescript is:
do shell script "diskutil eject /Volumes/name"
where "name" is the name of the volume. I can easily mount it anytime I need to access the files on it. Ahh, back to silent operation.

The August 1953-dated track diagram suspended from the roof in Vitriol Works signal box. Thursday 18th February 1988
Vitriol Works signal box is located on the up side of the line at Chadderton, and is a British Railway London Midland Region Type 14 design fitted with a 65 lever London Midland Region Standard frame which opened in 1953 in connection with the new Chadderton B electricity generating station, replacing a 1903-built 46 lever Lancashire and Yorkshire Railway Standard design signal box located a few yards to the north. All of the glazing at the Manchester end of the signal box, with the exception of one pane by the front corner was bricked up in spring 1988. More problems with the windows meant the sliding sashes were replaced by 1997. The signal box was rewindowed and a new set of metal steps were provided in the mid-2000s
Carried on the block shelf are (left to right) a British Railways Standard absolute block instrument to Middleton Junction West signal box on Up Slow line, a London and North Western Railway block bell and a British Railways Standard absolute block instrument from Middleton Junction West signal box on Down Main line/to Middleton Junction West signal box on Up Fast line, a signal post telephone for 32 signal, a London Midland and Scottish Railway pattern closing switch, a Lancashire and Yorkshire Railway absolute block instrument and a London and North Western Railway block bell from/to Thorpes Bridge Junction signal box
Although dated August 1953 the diagram actually dates from the late 1970s/early 1980s when the Down Goods line to Middleton Junction West was abolished. The diagram has a red coloured track circuit on the approach to down home signal. A red coloured track circuit indicated the track circuit controlled the block instrument needle indication, a practice that has now ceased.
The diagram’s amendment of 25 and 26 signal was after the replacement of a two doll London Midland and Scottish Railway cantilever left-hand bracket on a lattice main stem located in the ten foot between the Up Fast and Up Slow lines by a tubular post and a London Midland and Scottish Railway 1941 type standard dwarf signal located at the end of the Up Slow line
Behind the signal box’s location when the railway opened was Messrs Hannibal Becker and Company’s works. It is shown on the 1848 Ordnance Survey map as Slacks Valley chemical works, and although the works does not appear to have been rail connected the name is thought to originate from the works
