-
- is a small tool to edit any data on your disc(s) or just show some
- informations about the disc(s).
-
- When started you will be prompted for the filesystem and drivenumber you want
- to inspect (drivenumber only if more than one on the selected filesystem).
- Please type in the numbers for the filesystem and drive you want to edit.
- After this you will see a screen which shows the first bytes on your disc.
-
- Furthermore you'll see the disc-address and cursor-offset on top of the data
- as well as the value under the cursor in decimal, ASCII and hexadecimal.
-
- Now you are able to do the following :
-
- - moving around with the cursor-keys and modify the value under the cursor
- by typing the new value or pressing the corresponding key.
- - press F1 : you will get a help-screen, return with the space-tab.
- - press F2 : some general informations about the current disc are shown,
- again return with space-tab.
- - press F3 : rewrites the SHOWN data back to disc !!!
- - press F4 : lets you change the disc if more than one available (configured)
- - press F5 : saves the current data-buffer into memory to restore it later.
- - press F6 : restores the previous saved data onto the current buffer.
- - press F7 : you can enter a text which is searched on the whole rest of
- the disc, beginning at the current disc-address (search is not
- case-sensitive). This is not yet available for DOS-discs, sorry.
- - press F8 : you can enter a new disc-address. This can also be an expression
- such as 20*1024*1024 or &6C00.
- - press F9 : enter a shell (command-line-modus) - this can be used very well
- for getting a start-address of a file with *FILEINFO filename.
- Leave the shell by pressing only the Return-key.
- Now you can use F8 to jump to the address shown in the fileinfo.
- - press F10: save the current buffer (1024 bytes) as a normal file (&FFD).
- - press F11: change the system to ADFS, SCSI, RAM or DOS and drive (like F4).
- - press F12: will check the surface of the current disc (harddiscs only).
- You can enter the stepwidth of the check to localise any error
- closer each step. Depth 0 means very close (512 bytes), depth 4
- means a wide (but faster) scan (8192 bytes).
- In all stepwidths the whole disc (without gaps) is scanned
- beginning at the current disc-address.
- If an error is found its disc-address is shown and you have to
- press the Return-key to continue.
- During the scan you can press the space-bar to abort the scan.
- - press Esc to quit the program without saving the buffer back to the disc.
- - press Print to perform various speed-tests.
- - press PageDown to jump to the next 1024-byte-block or wrap at end of disc.
- - press PageUp to jump to previous 1024-byte-block or wrap at start of disc.
-
- !!!!!!!!!! Please be extremly careful when using this tool !!!!!!!!!!!!!!!
-
- As this program reads and writes directly from or to the disc you are
-
- able to modify ANY data on the whole disc very easily !
-
- Directories, maps, sector-ids and all the other nice things which have
- to be absolutely unaffected for a correct filing-system could be modified
- when you are writing to those areas on the disc.
- This might have the result that many of your data could be lost and even
- that you have to reformat the disc if the damage becomes too large.
-
- So please only use this tool with care and always keep in mind what you're
- doing to the disc !!!
-
- Because of these points this tool should only be used by experienced users !
-
- Nevertheless I hope you find this small tool useful.
-
- Best regards, yours Mike G.

- Of course this program is Public Domain !!!
