How to scan and recover if partition exists but damaged?

Problem:

A virus infected my computer system. Now it does not boot. FDISK shows partition of unknown type. Active@ UNERASER shows partition of "Unknown" type and does not allow previewing and scanning of partition.

Reason

When partition is damaged, for example partition type is "Unknown", Active@ UNERASER does not know how to handle it properly, so it does not allow you to preview files on it. However partition exists and there is no "Unallocated" space (partition space is occupied). So Active@ UNERASER detects that there is nothing left to scan.

Solution

While starting the program, use parameter -ignoreMBR that explicitly tells Active@ UNERASER to ignore default MBR and partition information, and the whole drive will be available for the scanning, for example:

A:\>UNERASER.EXE -ignoreMBR=80h

This way you will see "Unallocated" space under HDD 80h.

Try to scan it by pressing [ENTER], and follow the procedure described in topic:
