I know that sectors are addressed using a CHS scheme.
C is the cylinder to read, and controls the positioning of the read-write head mechanism. Its lowest possible value is 0 (zero).
H is the head (or track) on a given cylinder, and it selects which read/write head should be used for the read or write operation. Its lowest possible value is also 0 (zero).
S is the sector on the current track and cylinder which is to be read. It tells the drive how properly time the read or write operation so that the rotation of the disk is at the exact correct spot on the current track for the read/write head to perform the read or write operation. Its lowest possible value is 1 for some reason.
What I really want to know here is what is the access order, for reading and writing sectors sequentially? The first sector has CHS address = 0,0,1. But what is the address of the second sector? Is that 0,0,2? Or maybe 0,1,1? Does anybody know this? Or is this lost knowledge from the days of old computers, that nobody even knows anymore? I know one thing, and that is I haven't found this info yet from any Google searches. So that's why I'm asking here.
