REBUILD MASTERBOOT RECORD
HANDLING VIRUSES
There is a fixed disk sector editor in Micro-Scope that allows you to view and modify any data anywhere on the
surface of the platter – even those reserved areas that
are normally off limits to DOS utilities, like track Zero,
for example. That is very handy if you have to do any repair
or reconstruction of the Master Boot Record or Partition Tables,
perhaps due to a virus contamination.
Screen - Fixed Disk Select
In fact one of the menu items in
Micro-Scope is called 'Rebuild Master Boot'
and it is a completely automatic function. We include this
function since about 80% of the common viruses attach themselves
to the Master Boot Record.
Micro-Scope does a destructive
low level format, just on Sector 0 to wipe out the virus and
then it automatically writes a DOS Master Boot Record in its
place. The entire procedure takes less than a
second and provides for instant access to the data on the
drive.
REBUILD MASTERBOOT
The Rebuild MasterBoot option will
rewrite the first 446 bytes of the master boot sector with
a generic DOS boot loader program.
Screen – Rebuild Masterboot
The Master Boot Sector contains
a boot loader program (446 bytes), Master Boot Record (64
bytes) and a 55 AA boot signature (2 bytes).
When the BIOS looks at the Master Boot Sector
on the C drive and finds a 55 AA boot signature at 01FE, the
BIOS turns control over to the boot loader program at 0000.
The boot loader program then loads the Master
Boot Record at 01BE.
If the boot loader program is missing or
corrupted, the Master Boot Record will never be loaded and
the C drive will not boot. It is still possible to boot
to the A drive then go to the C drive.
Press Y (Yes) to rewrite the Master Boot
Sector. Press any other key to cancel write operation.
Low Level Format
With Micro-Scope you can
do a true factory low-level format on any drive type, regardless
of the size, make or model, even SCSI and IDE drives. Also
if track Zero is damaged it will relocate track zero and fix
those drives.
The difference between Micro-Scope
low-level format and other diagnostics low-level format is.
A. Other diagnostics use a bios call
to perform there low level Format routine. This routine is
the reason why drive manufactures print on the side of the
drives (DO NOT PERFORM A LOW LEVEL FORMAT. SEND BACK TO MANUFACTURE)
B. Bios low-level formats only have the capability to
get rid of the indexing system. The information can still
be recovered. So for security purposes this is not good. Not
to mention that the old registries are still on the drive.
This is what will cause the drive to crash again.
C. Micro-Scope's low-level format is
a factory style low-level format. Micro Scope can first do
a secure wipe of the drive by writing zeros to the entire
drive not being limited to any partitions that other utility
cannot see.
D. Then to reinitialize the drive back
to the factory specifications. Micro-Scope
will communicate with the drives command Register where the
information exist to bring the drive back to the factory specs
and if there is a virus on track zero. Micro-Scope
will relocate track zero.
The low-level format routine is what got
Micro 2000 a GSA contract with the USA government. The ability
to declassify a hard drive.

Recent Review:
 "In
the service business, time is money. The Micro2000 Universal
Diagnostic Toolkit is worth its weight in gold for any service
company. The cost of the product is quickly recovered because
of faster turn around time when fixing problem systems. The
product also helps control business costs simply because technicians
are more accurately diagnosing what parts they require for
system repairs." Compunotes
