Well it is remote at the moment.  I'll try to get the info from the BIOS.
Here is what the Maxtor site says:

SECTOR ADDRESS TRANSLATION:     
+---------+--------+----+---+-----+-----------+------------+
| Model   |  CYLS  | HD |~LZ| SPT | Capacity  |  MAX LBA   |
| Number  |    *   |    |&WP|     |    **     |            |
+---------+--------+----+---+-----+-----------+------------+
| 54098U8 | 16,383 | 16 | 0 | 63  | 40,980 MB | 80,041,248 |
+---------+--------+----+---+-----+-----------+------------+

So "66,055,248" is a lot lower than 80,041,248.

For comparison, my "92048D8" 20GB is listed like this:
SECTOR ADDRESS TRANSLATION:     
+---------+--------+--------+----+---+-----+-----------+------------+
| Model   | Actual | Max    | HD |~LZ| SPT | Capacity  |  MAX LBA   |
| Number  | CYL    | CYL*   |    |&WP|     |    **     |            |
+---------+--------+--------+----+---+-----+-----------+------------+
| 92048D8 | 39,683 | 16,383 | 16 | 0 | 63  | 20,480 MB | 40,000,464 |
+---------+--------+--------+----+---+-----+-----------+------------+

NetBSD sees:
wd0 at pciide0 channel 0 drive 0: <Maxtor 92048D8>
wd0: drive supports 16-sector pio transfers, lba addressing
wd0: 19531 MB, 16383 cyl, 16 head, 63 sec, 512 bytes/sect x 40000464 sectors
wd0: 32-bit data port
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 2
wd0(pciide0:0:0): using PIO mode 4, Ultra-DMA mode 2 (using DMA data transfers)
