GWSCAN
PROGRAM DESCRIPTION:
This MODULE of the Data Lifeguard Tools program searches for and
verifies the status of specific Western Digital drives. By accessing
the Data Lifeguard information stored on the hard drive, the program
is able to quickly and efficiently verify the status of the drive.
If any errors are logged or found, it provides an option to return the
drive to defect-free status through an extended test or repair option.
GWSCAN offers several options for verifying the defect-free status of
your hard drive.
QUICK TEST: The Quick Test is designed to intelligently gather and verify
all of the Data Lifeguard information contained on the drive. The Quick
Test can determine with a high level of confidence that a drive is
defect-free in a short amount of time. For maximum confidence, the
Extended Test is recommended. The Quick Test option may not be available
on earlier hard drives.
EXTENDED TEST: For most computers the GWSCAN Extended Test takes 5-20
minutes to test one drive. Larger drives take longer to test. The
performance of the computer also affects the test time.
TO RUN THE PROGRAM:
BACK UP DATA:
Before running GWSCAN, it is recommended that users back up all data
for all hard drives. This utility may write to the drive during the
re-certification process. As with all utilities that write to a drive,
it is recommended that you back up your data before proceeding.
STORE THE PROGRAM ON FLOPPY DRIVE:
The program must be run from a floppy drive, so if downloaded, copy all
files included in the zip to a formatted bootable floppy diskette in A:.
All files must be included for the program to function properly. Running
this program from the target hard drive while using certain operating
systems can result in data loss and an inaccurate scan of the target
drive.
START THE PROGRAM: To start the program, type GWSCAN at the
A:\ DOS prompt.
TO TEST EACH DRIVE:
Pick the 'Select Drive' option to see a list of all drives
installed and the current status of each drive.
For each drive that shows a status of 'DRIVE NOT TESTED', select
the drive by using the up/down arrows until the desired drive
is highlighted and hit ENTER, then return to the main menu to test
the drive.
Once the target drive is selected, choose either the Quick or
Extended Test Options. The Quick Test option may not be available
on earlier drives. If it is not available, then the program will
give the user the option to run the Extended Test.
Depending on the option selected, the 'Test' will take between 90
seconds and 20 minutes to complete (depending on the size of the drive
and the speed of the computer).
At the end of the test a status is displayed. Also, the status for
all drives is always available by choosing the 'Select Drive' option
from the main menu.
If errors are detected during a 'Test' option, the user will be
given the option to attempt to repair the errors.
Use the 'Select Drive' and 'Quick Test' and 'Extended Test' options
to select, test, and repair each drive until all drives have been
tested.
Pick QUIT from the main menu to quit the program. At this point
a message will inform you that the system should be reset to
reinitialize the BIOS and hard drive(s). Hit CTRL-ALT-DELETE or
turn the power off to restart the system.
When rebooting, remove the floppy diskette so the system boots
to C: instead of A:.
TO CONTACT TECHNICAL SUPPORT:
In some cases the user may be requested to contact TECHNICAL SUPPORT.
Consult your drive or system manual for contact information.
MAIN MENU OPTIONS:
Select Drive select drive and view status for all drives
Check Smart Status check Smart status recorded in the drive

Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
