2.2.2. 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
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.
Figure 2-7 Perform Extended Disk Scan
After these steps, there is an example:
-
In the Detected Drive screen, position the cursor to the defective
drive.
-
On the keyboard, press [Ctrl+Enter]. The utility begins scanning the
drive surface, ignoring existing partitions and drives.
-
When a drive or partition is detected, a screen dialog will suggest adding it
to the partition table.
(!) Caution: Pay attention to the size of each
detected partition and add only those partitions about which you are certain of
the contents. Failure to attend to this detail might result in unrecoverable
data. Once a detected partition is added to the partition table, the amount of
space equal to the listed partition size will not be scanned further.
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 2-8 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 2-1 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 2-2 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.
