- In the world of disks and data
recovery we start counting disks at 0 (zero). So the first disk is 'disk
0', the second disk is 'disk 1', etc.
- If you use the bootable CD/DVD
you will need to find a target location for the files that DiskPatch
creates when it's running; they can't be saved to the CD/DVD. You
will either need a FAT formatted partition somewhere that can hold
the files, or you can use a FAT formatted USB stick/key or USB disk
to receive the files (read more here
on how to prepare a USB key). DiskPatch will ask you where to save the files
if the files can not be saved to the current location.
- Use the cursor keys to navigate
the menus, use the <Enter> key to select an option, use the
key to abort or leave a menu.
Here we go:
|Start DiskPatch and select the
example: your screen will differ. Find more
information on how to select a disk here.
|After selecting the disk, the menu
will expand, showing actions that can be performed for the selected

|Now select 'Perform repairs', then
'Rebuild partition tables'.
Select how the partitions that
we're looking for were
created (read more here).
|Please note: if the
resulting list of partitions is incomplete you should run the 'Full
scan'. You can read about the difference between the two modes here.

|When the scan has completed the
following display will be shown.
|Now it's your turn. Select the
partitions that need to be recovered. Make sure to include all
partitions you want back; also select the ones that were okay earlier.
DiskPatch always rebuilds the entire partition table so it needs to know
which ones to include.
Selected partitions are indicated by the checkmark on the left of the
If the list is long and cluttered you can use the 'display filters' to
clean it up, read the corresponding
part of the manual.
Please note that after a quick scan DiskPatch has already selected all
eligible partitions (as is displayed in this screenshot), so you won't
have to do anything unless the list of selected partitions is incorrect.
|If you need to change the
selection, Use <Enter> to display the partition select menu:
|Once you're finished with the
'partition select' display, press <Escape> to continue to the repair
phase. The following screen will be displayed:
|Select 'Start repair'. DiskPatch
will ask you if you wish to create an undo file (recommended), if this
option is enabled.
Enter a description or leave the default suggested text. Press
at this point to skip creating the undo file (not recommended).
|The repair will now start. A status
display will tell you what's going on:
|After the repair DiskPatch will
show a completion screen. The repair is now finished. Press a key to
close the completion screen, DiskPatch will now return you to the menu.
|Things to consider when the repair
has been completed:
When the partition tables have been rebuilt, DiskPatch does not set an
active partition. This is intentional and will prevent you from
accidentally booting into a partition that may still suffer other
damage. If you're confident that things are okay you can use
DiskPatch to change the partition status and set an active
partition. Check this guide for an explanation on how to
- If the MBR was damaged you may
need to refresh the MBR boot code. Check this guide for
an explanation on how to do this.
- If you need to perform another
partition table repair (because you selected the wrong partition, or
because you wish to try another partition) you need to re-scan the
