i know, im getting very annoying posting thousands of questions, well i think i am. but the bios int 13h says i can load multiple sectors, say

one way of doing it: ;loads 5 sectors at once
load 5 sectors
ret


or

another way of doing it: ;loads a sector at a time, 5 times
load one sector
cmp register, 5
je done
sub register,1
jmp another way of doing it



would function #2 wear on the floppy disk drive?

3 times is enough.

1 sector at a time, 3 retries (if cf set or reset (don't remember exact value)

i tested many possibilities with bios. the only who always works is that one.

then, do that:

I always use one sector at a time and have the same test PC and floppy drives for over 5 years, with no problems with wear etc.

thanks

Have you ever run out of retries?

It happens with dead/dying disks with bad sectors.
The FDC can be quite "stubborn", but 3 retries should be good.
