How to remove the hard-disk password

Attention: If User only mode is selected and the user HDP has been forgotten and cannot be made available to the servicer, IBM does not provide any services to reset the user HDPs or to recover data from the hard-disk drive. The hard-disk drive can be replaced for a scheduled fee.

To remove a user HDP that has been forgotten, when the SVP and the master HDP are known, do the following:

1.Power on the computer by pressing and holding F1.

2.Enter the SVP. The IBM BIOS Setup Utility menu appears.

3.Select Password, using the cursor keys to move down the menu.

4.Select Hard-diskx password, where x is the letter of the hard-disk drive. A pop-up window opens.

5.Select Master HDP.

6.Enter the master HDP; then leave the New Password field blank and press Enter twice.

7.Press F10.

8.Select Yes in the Setup Configuration window.

Both user HDP and master HDP will have been removed.
