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.
