Option 4 of the RescueBRU main menu (Disk Utilities) allows you to 
perform various drive maintenance actions. These actions are 
described below.
 
Clone disk
RescueBRU generates a list of hard drives. You are then prompted to 
select the source and destination drives from menus. You will then 
be asked to confirm your actions and an exact block by block copy of 
all data on the source drive will be created on the destination 
drive. The operation may take a long time for large drives. A 
progress indicator will be shown. When the clone is finished, you 
will be returned to the Disk Utilities menu.

Blank disk
RescueBRU generates a list of hard drives. You are then prompted to 
select the target drive for blanking from a menu. You will then be 
asked to confirm your actions and all data on the target drive will 
be overwritten with zeros. This will destroy the MBR, the partition 
table, and any RAID signatures that may exist on the drive. Any data 
that exists on the drive will not be recoverable. NOTE: This will 
not satisfy the US DoD 5220.22-M standard and will not serve to 
"declassify" a drive. If the drive contained classified data, it 
will still need to be stored and controlled in accordance with the 
highest classification it contained. When the blanking operation is 
finished, you will be returned to the Disk Utilities menu.

Test disk for bad blocks
RescueBRU generates a list of hard drives. You are then prompted to 
select the target drive for testing from a menu. You will also be 
prompted whether you want to do a read-only test or a write/read 
test. You will then be asked to confirm your actions and the test 
will begin. If you have selected a read-only test, no alteration 
will be made to any data on the drive.If you have selected a 
write/read test, all data on the target drive will be overwritten by 
various bit patterns, and finally with zeros. This will destroy the 
MBR, the partition table, and any RAID signatures that may exist on 
the drive. Any data that exists on the drive will not be 
recoverable. NOTE: This will not satisfy the US DoD 5220.22-M 
standard and will not serve to "declassify" a drive. If the drive 
contained classified data, it will still need to be stored and 
controlled in accordance with the highest classification it 
contained. When the blanking operation is finished, you will be 
returned to the Disk Utilities menu.
 
Setup backup media
If using the "Local" media type, media setup is not required. For 
the RescueBRU utility to work,the backup images must be stored on 
the backup media in a place where RescueBRU can find them. This 
option creates the directory on the backup media where the images 
will be stored. After selecting this option, RescueBRU mounts the 
media, and then checks to see if the backup location already exists. 
If it does, RescueBRU warns you that if you continue the setup, you 
may lose old backups. You have the option of continuing anyway or 
aborting media setup. When a backup is started, the media is checked 
to see if it is set up and this function is automatically invoked if 
it isn't. Consequently, you should never have to use this option. 
This option is really only useful if you want to purge all existing 
backups from the media.
