How to use Active@ UNERASER for Disk Image creation?

Problem:

A Disk Image is a copy of the drive saved in file. Disk Image can be useful for backup/restore purposes or, even for the analysis by other utilities. Using Active@ UNERASER you can create Disk Image for the whole HDD (Hard Disk Drive) as well as for the particular logical drive.

Solution

• Start Active@ UNERASER
• Select the drive (HDD or Logical) you want to create image for
• Press [Ctrl]+[I]
• Select path on another logical or network drive where disk image will be saved
• Press OK or [ENTER] key, see the progress and wait until creation of disk image is finished

Another way (available in Professional version only) is to run software with parameter -image, for example:

A:\>UNERASER.EXE -image80h=E:\par

Created Disk Image is set of files: Drive_80h.hdd, Drive_80h.001, Drive_80h.002...

Each file (except the last one) has size 1GB. Reason for files separation is that MS-DOS does not support files having size more than 2GB. If you need disk image of the whole drive in one file - you can merge them later on manually.
