I'm trying to write a program (in Turbo C 2.0) that scans the hard disk looking
for certain file signatures.  I want this program to scan sector by sector, so
I tried using int 25h via the Turbo C absread() command.  The problem is, the
program works as intended on drive C: which is a 20 meg PC-DOS 5.0 partition,
but not on drive D: which is a 300 meg partition (same OS).  The call keeps
returning a "sector not found" error even for low sector values.  Can anyone
shed any light on this?  Thanks in advance.
