Much easier said than done. :-) I gave up until I committed to buying a
new drive.

Perhaps this is the reason some people (including me) found that the
connector doesn't exactly fit the new drive. I suspect IBM wstandardized
dimensions between the 170 and 340 drives soon after production. It seems
I got one of the older ones, and the 340 label on your cable suggests you
got one of the later ones.

Yes, they're standard. That's why they're available as OEM drives. To fit,
the drive has to be 17mm high or less. Most of the 2.5" drives out are
19mm, and some (none over 250 MB last I checked) are 14mm. You *might* be
able to fit a 19mm drive without a housing.

I was told by two different IBM people (both in notebook development) that
the TP will accept any IDE drive that correctly responds to IDE queries for
number of heads, cylinders, sectors, etc. i.e. it doesn't rely on a lookup
table in the BIOS for the hard drive information - it asks the drive.
A BIOS update was necessary for the 540MB and 810MB drives because they
exceed the standard IDE size limit of 512MB. The new BIOS allows EIDE
drives which can be larger than 512MB.
