- What's new ?
- ------------
- - Added Abort/Retry/Ignore Box to handle Sector Read/Write Errors
- - Fixed the problem that the cursor might jump between rows when editing sectors
-
- Overview
- --------
- HPFSTool contains a *real* Undelete for OS/2 HPFS-Drives. That means that you
- don't have to use the DELDIR statement in CONFIG.SYS like in other "UnDels".
- You are able to recover almost any file that has been deleted on any HPFS-Drive
- in your system.
-
- Also you have a PM-based sector editor included which makes it possible to
- view and modify sectors on every harddisk or floppy drive in your system.
-
- This program is ShareWare. You can make as many copies as you want and give
- them away to other interested people. You have 25 free trial executions
- to find out if this program fits your needs and works the way you want.
-
- If you plan to use HPFSTool regulary you must register it (More details
- about registration at the end of this text).
-
-
- Installation
- ------------
- The usage is quite simple. Copy all files to a directory on your harddisk
- and then start HPFSTOOL.EXE. In the startup dialog you can see the remaining
- trials in the entryfield 'Serial Number'. Press the buttons 'English' or
- 'Deutsch" to select the language for the program. When the main window
- shows up select 'Undelete' or 'Edit'.
-
-
- Undelete
- --------
- First select the drive using the 'Drive' spinbutton. Then press 'Scan' to scan
- that drive for deleted files. If you know the name of the file you may enter
- the first 15 characters in the entryfield 'File'( no wildcards like * or ? ).
- If you leave this field blank then all deleted files are displayed.
-
- While scanning the 'Scan' button changes to 'Stop' so that you can abort
- scanning at any time you want. Because of the HPFS-structure it is necessary to
- scan _all_ free sectors on the drive to find deleted files so scanning can take
- a few minutes depending on the size of free space on the drive.
-
- Select the file you want to recover from the list and press 'Undelete' or
- doubleclick on the file to recover it. When selecting a new path for the
- recovered file keep in mind that you should not store the file to the same drive
- if you plan to recover more then one file. This is because the first recovered
- file may overwrite some parts of the other deleted files that you also want
- to recover.
-
- If you get the message "Unable to lock drive X:" that means that the program
- can't get exclusive access to that drive. This occures if at least one other
- file is currently open on this drive. Therefore it is impossible to lock
- the boot-drive and the drive with the SWAPPER.DAT on. You may proceed with
- Undelete but make sure that no other process acesses this drive and no
- paging occures while Undelete is in progress.
-
- The 'Wipe' button removes all information about the deleted file so that
- it can never be recoverd. This may be used for security reasons or to
- clean up some *.###, *.$$$ files.
-
- Deleted files are only listed if they could be completely recovered, that means
- no partial recovering is possible. Undelete also tries to find the path where
- the deleted file was located before deleting. If the path could not be found
- only '???' is shown.
-
- HPFSTool disables "Lazy writes" on HPFS drives because it accesses the disk
- directly without notifying the file system driver and it's cache management !
- To turn on Lazy writes after using HPFSTool enter 'DETACH CACHE /LAZY:ON' on
- the OS/2 command prompt. (Note the DETACH statement !)
-
- Before using the Undelete function check the following things:
-
- - Stop any other program that may access the drive and avoid paging
- if the SWAPPER.DAT is on that drive.
-
- - If necessary call CHKDSK to check the drive for errors.
-
- - After deleting a file that you want to recover avoid writing to the
- drive wich the deleted file was on.
-
-
- Sector editor
- -------------
- Select a drive using the 'Drive' spinbutton and select a sector via the
- 'Sector' spinbutton. If you want to edit a floppy disk you have to insert
- the disk before you run the sector editor. You can change the display format
- of the sector to 'Data'(Hex-mode), 'Boot'(Boot-sector mode) or 'FNode' (file
- information block which contains information about a file on HPFS drives) by
- using the 'Format' spinbutton.
-
- Press the 'Copy' button to copy the contents of the display to the clipboard.
- If you want to change the contents of the sector activate the edit field via
- TAB-key or mouse and enter the new values. Pressing the 'Clear' button fills
- the whole sector with 0. To write the modified sector back to disk press
- the 'Write' button.
-
