- This little toy is designed to allow you to examine the sector
- allocation on your disks. Instead of using the DOS to find files, it uses
- the trackdisk.device and examines the sectors directly, traversing the
- filesystem "by hand."
-
- This is written for the Manx compiler; conversion to Lettuce may
- or may not be trivial. To make this beastie, first download all the files,
- then do this:
-
- 1> make
-
- Simple, isn't it?
-
- SYNOPSIS
- fm [device [file]]
-
- DESCRIPTION
- fm is a utility that allows you to examine the sector allocation of
- files on your disk.
-
- Unallocated sectors are the background color; file control blocks
- are rendered in color 1; data blocks are color 2; and sectors allocated by
- other things show up as color 3.
-
- Files to be examined are entered in the filename gadget. All
- filenames must be a full path from the root. When entered, the program will
- then attempt to find the file and display its allocation on the screen. If
- an error occurs, the program will inform you. Errors may or may not be
- fatal. However, the program does clean up after itself rather well.
-
- To change devices, enter a new device name in the device gadget.
- The program will then load the bitmap off the new device and display it. If
- you wish to examine a different disk in the same device, you *must* hit the
- device gadget and then press RETURN. Failing to do this causes (non-
- destructive) problems, since the bitmap sector number is cached.
-
- To re-display the current device/file, hit the refresh gadget. This
- is useful if another task is running concurrently and writing to the disk.
- Hitting refresh allows you to see the changes made to the disk.
