Behold, the product announcement below, for the 1.4GB and 2.1GB, reference
the product announcement number or option number when talking to IBM and
then miraculously they will see that those drives exit. The only catch is
these IBM drives don't come cheap, I think someone quoted $1500 for the
2.1GB drive.

Overview
Options by IBM extends the life of your mobile systems by announcing
two new exciting upgrade options for ThinkPad(R) 760 and 755 systems.
As your mobile system needs continue to accelerate, you can increase
capacity and enhance the value of your ThinkPad system with a new
high-capacity hard disk drive (HDD) upgrade. The ThinkPad 760/755
1.4GB HDD 3L is a super-slim (12.5 mm) profile, 2.5-inch HDD that can
be easily added as a second drive in any ThinkPad 760 Ultrabay, or
used to replace the original drive in any ThinkPad 760 or 755 system.
For extraordinary capacity requirements, the ThinkPad 760/755
2.1GB(1) HDD 2X is a low-profile (17 mm), 2.5-inch HDD compatible
with "thick-based" ThinkPad 760 and all 755 systems.
Both drives incorporate advanced Magneto-Resistive (MR) head and
No-ID sector format technologies developed by IBM. MR heads enable
higher areal densities, thereby reducing the number of disks and
heads for a given drive capacity.
No-ID sector formatting further increases the storage capacity by
eliminating the overhead caused by the duplicate storage of each data
sector's ID fields on the disk, and uses that disk space for
additional user data. MR head technology, combined with No-ID sector
formatting, enables the drives to deliver high capacity and enhanced
performance in a reliable design.
These disk drives are ideal for ThinkPad system users with ever
increasing requirements for emerging technologies, new applications,
and data storage. Integrated fax, graphics, Internet, and multimedia
won't be held back by lack of disk space. The mobile system user
does not have to sacrifice desktop storage capacity to stay on the
go. IBM HDDs are designed with key mobility features to meet
customer needs of ruggedness and low power consumption.
Both ThinkPad HDDs are easily installed and removed by the end user.
One mobile system can be shared by multiple users by giving each one
their own disk drive for personal applications and data.
IBM's HDD options are designed to balance the requirements of
capacity, performance, size, enhanced power management, and
ruggedness to meet the exacting standards of the ThinkPad customer.
This is an excellent reason to upgrade your ThinkPad with original
equipment, designed specifically for your ThinkPad's features.
Intended Customers
ThinkPad 760/755 users who require desktop storage capacity on their
mobile systems.
Key Prerequisites
These new HDDs are supported on selected ThinkPad 755 and 760 models.
Refer to the Hardware Requirements section for specific details.
