3.3.3. Extended Disk Scan
Extended Disk Scan is to be engaged if any of the following is
true:
- Scanned Unallocated areas reveals nothing
- You suspect that partitions have been damaged
- New partitions have been created and used on top of deleted
partitions
Figure 3-12 Extended Disk Scan

Extended Disk Scan is similar to the command line parameter -ignoreMBR
in that the Master Boot Record is ignored, allowing access to disk
data. Using this new feature, however it is not necessary to exit the
program and run software in command mode with a parameter.
Scanning starts for the whole drive's surface ignoring existing
partitions and drives. All detected drives and partitions, existing
and previously deleted (even you've re-partitioned and re-formatted
the HDD) will be added to the drive's list and you can try to scan
them looking for your data.
Example of Extended Disk Scan.
An original disk contained three partitions with the following sizes:
3GB, 1GB and 4GB. The second and third partitions have been deleted and
two new partitions have been introduced with these specifications: 2GB
and 3GB. (see figure below)
Figure 3-13 New Partitions Created.

After the new partitions have been created, you recall some important
data on the old 4 GB partition. The table below displays what the
Extended Drive Scan will report, showing actions to be taken:
Table 3-2 Extended Disk Scan
Suggested Partition Size |
Action |
3 GB |
Accept it [Y] |
2 GB |
Skip this partition in order to scan the space underneath |
4 GB |
Accept this partition. The size shows that it is the partition containing your important data. [Y] |
The table below displays the differences between Extended Disk Scan
and the DOS command-mode parameter -ignoreMBR:
Table 3-3 Extended Disk Scan vs. -ignoreMBR
Extended Disk Scan |
-ignoreMBR |
Runs in DOS interface mode |
Runs in DOS command mode |
| All detected partitions are added as primary partitions (logical drive
structure ignored).
|
Detected partitions are added, maintaining logical drive structure.
Disk is restored exactly to the same state it was before data removed. |
