Question
How do I remove EZ-BIOS from my Non- Western Digital drive?

Answer
The Data Lifeguard Tools software can be used to remove the EZ-BIOS program installed on a non-Western Digital drive.

The software will not run without a Western Digital drive installed, so make sure it is connected to the system while removing the software from the other non-Western Digital hard drive.

Boot to the Data Lifeguard Tools diskette. Instructions for downloading and extracting this software are available by clicking on the link below.

At the main menu, select "EZ-Install" by highlighting it and pressing Enter. Data Lifeguard Tools EZ-Install will start to load, bringing you to a Welcome Screen; press Enter to continue past this. The License Agreement will now be shown; press Enter to continue past this. You should now be at the main menu of EZ-Install.

At the main menu of EZ-Install, highlight "Advanced Options" and press Enter to select it. From the Advanced Options menu, highlight "EZ-BIOS Setup" and press Enter to select it. A message may appear informing you that EZ-BIOS is needed to control your drive and offer to install it. Answer "No" if it asks this. A box will appear showing you the drives that you have installed in your system, highlight the correct drive and press Enter to select it. Once the correct drive is selected, another menu will appear, and an option labeled "Controlled by EZ-BIOS" will be listed. To the right of this option it will say "Enabled". Highlight that line and press Enter to change it to "Disabled". Highlight "Save the changes and exit" and press Enter.

EZ-BIOS is only disabled at this point and has not been completely uninstalled. Remove the Data Lifeguard Tools disk and reboot into Windows. The drive should now appear under My Computer and you should be able to access your files. If so, reboot to the Data Lifeguard Tools disk and navigate to the EZ-BIOS Setup menu by following the steps you just performed. After selecting the correct drive, the option "Uninstall EZ-BIOS" will now be shown. Highlight this option and press Enter to uninstall. Exit the program and reboot the system without the diskette in the drive. Your system BIOS is now controlling the drive normally.

Even though a Non- Western Digital drive is involved here, I think you can still use the procedure.
