You can get this information by running the NORTON UTILITIES and selecting
the "TECHNICAL INFORMATION" item under the "DISK INFORMATION" menu.

My disk controller manual has a table of disk drive characteristics. (Which
is a reflection of the BIOS ROM table).

The program DISK MANAGER will determine the disk geometry and display it.

You can also poke around the ROM with debug to find the table. My table is
around C800:8020.

Of course, neither NORTON UTILITIES or DISK MANAGER are PD programs.
