[fpc-pascal] Low level disc access under windows with FPC

Sun Oct 8 14:08:53 CEST 2006


        Hello, I'd like to ask if someone has experiences with low level
disk operations in windows with FPC.
The program should be able to copy entire diskete to one single image file
and for example extract a single file from that image or view its contents.

For example how can I read one sector from disk in to buffer?
Thanx for help
Pianoman
