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:

1. In the Detected Drive screen, position the cursor to the defective drive.
2. On the keyboard, press [Ctrl+Enter]. The utility begins scanning the drive surface, ignoring existing partitions and drives.
3. 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:

The table below displays the differences between Extended Disk Scan and the DOS command-mode parameter -ignoreMBR:
