cdex sector read

[Mantra]

hi

in cdex setup I can setup the read sectors (to me is 27)

but does it change if i put for example 1 or 5? in extract mode

for example for scratched cds?

ps:
profiles- i can't save different profiles
it gaves me the same settings! why?

Changing the read sectors doesent have any connection with scratched cds...About profiles i dont have idea as i using eac or foobar only...
