I am trying to write some utilities, and on e of the things I need to do is add the possibilty to recover deleted files. So I need to examine the FAT table (this will be in windows) and possibly examine clusters on the hard disk. Any thoughts on how I can accomplish this in C or C++?

[NORMAL SOLUTION]
You can use the function from "DIR.H" or "DOS.H" as: findfirst(), findnext() and a builtin strucre ffblk.
[ADVANCED SOLUTION]
By absread() function which is used to read the desired secters(512 Kb) of disks, but must know the hardware oriented conceps of C, i.e. bits concepts, bitfield operators [&, |, !, ~, ^ etc] or you must know the detail of fat structure. For this purpose you can reffer complete MS-DOS manual or any good book.
