* verifyDrive() attempts to confirm that these values agree with the programmed drive characteristics.
*
* NOTE: For the record, in the world of PCjs, 1Kb is 1 kilobyte aka 1,024 bytes (NOT 1,000), and 1Mb
* is 1 megabyte aka 1024*1024 or 1,048,576 bytes (NOT 1,000,000).
*
* Apparently, in 1998, it was decided that a kilobyte should be 1,000 bytes and a megabyte should be
* 1,000,000 bytes, and that if you really meant 2^10 (1,024) or 2^20 (1,048,576), you should use "kibibyte"
* (KiB) or "mebibyte" (MiB) instead. Well, since PCjs simulates machines that pre-date 1998, I feel
* perfectly justified in retaining my original understanding of Kb and Mb and completely ignoring the
* existence of KiB and MiB.
*
* Besides, I suspect these changes were nothing more than a self-serving push by hard disk manufacturers,
* who wanted to exaggerate their disk capacities by treating Mb as 1,000,000 bytes.
*
* Also, I capitalize only the first letter of units like Kb and Mb, because kilobyte and megabyte are
* single words; if they were two words, or even a pair of hyphenated words, then I might -- but they're not.
