To put a Toshiba in your ThinkPad

[Chris Schumann <whizkid@home.dwave.net>]

I'm still getting requests for Toshiba hard disk installation
instructions, so I'll just post this, and hopefully it will be clear
enough. 

I have a ThinkPad 750P. This procedure will work for other 750's and may 
very well work on the 755's as well. (Can anyone verify for 701's and 
760's? 560? 36x?)

If you purchase a drive with a caddy, just pop it in.

I bought a MK1926FCV (810MB). The 1924 (540MB) and the 1.3GB UltraSlim are
the same size and should work just the same. Anybody's 2.5" 17mm thick (or
smaller) IDE drive should work (unless you have to turn the drive over, in
which case you may need to bust off the tabs in the caddy). 

This is based on my own experience and I believe it to be true, but don't 
complain to me if it doesn't work for you, and I won't be liable for 
anything you do to your hard drive and computer.

Note: ThinkPad drives are not hot swappable. Always shut down your machine
and turn power off before swapping a hard drive. 

(the good stuff)
To put a Toshiba drive into the IBM caddy:

Peel back the sticker over the drive connector and unscrew the two screw
holding the caddy together. 

Unsnap the six plastic tabs (three on each side) that hold the top part of
the caddy to the bottom part. I used a jeweller's screwdriver to do this. 

The caddy is hinged at the back (the edge closest to the user when in the
machine) so start with the tabs nearest the screws. 

You'll need to remove the drive cable from the drive. It has two
connectors and a short length of flexible printed circuit. 

Connect the cable to the new drive. The pins on the drive (indicated by X 
below) should line up with the holes in the cable (O below) as follows:
	xx xxxxxxx xxxxxxxx
	xx xxxxxxxxxxxxxxxx
	oooooooooooooooooooo
	oooooooooooooooooooo

This is not the exact number of pins, but the extra holes in the socket 
should be on the side away from the cluster of four pins. There are no 
keyed holes on the connector. If you connect the drive incorrectly, it 
will not work, and who knows what could happen.

Put the drive and connector assembly into the caddy. The drive is not as
thick as the IBM drives. As you close the caddy around the drive, ensure
that the protective plastic sheet that helps keep dust out is in the
bottom of the caddy. Suspend the drive from the plastic mounting nibs. 
The drive should not rest on the bottom of the caddy. (This made it 
difficult to slide out the keyboard locking tab.)

Line up the holes in the other cable connector with the holes in the 
caddy. It could take quite a bit of force to keep the connector in place 
as you re-assemble the caddy.

Screw the caddy back together (so everything lines up correctly) put the
sticker back in place and snap your new hard disk in your 'Pad.

When you turn the machine on, press and hold F1 to start the EZ-Setup 
BIOS and run the built-in test on HDD-1. If it works, you're all done, if 
not, good luck.

Now comes the fun part of installing software on a blank machine. Get some
DOS floppies and either install DOS or run fdisk and format before
installing other goodies. (I would personally format the whole drive from
DOS just as another test.)

I installed PC DOS 6.1, then Windows 95 upgrade from floppies (using a 
3.1 floppy as proof of upgrade path).
