don't shoot me for saying this, but.....
I'd assume that you are using the stock rb1773 driver on that disk, and not

Have you noticed any problems reading disks in Disk BASIC (yeah, yeah, I
know.... I should wash my mouth).

Besides a mathematical inclination, an exceptionally good mastery of one's
native tongue is the most vital asset of a competent programmer.
