世界這麼大，我不敢說一定解不開，但至我沒看過有人解開過，
為了確認版主的問題，我重新拿HP NC6230 及二顆型號相同的HDD，再試一次，
進BIOS 設Drive Lock HDD 需要設定二組PASSWORD，一組是USER PASSWORD(這組是
開機要打的PASSWORD，不打或打錯無法使用HDD)，另一組是MASTER PASSWORD(這組
是要解開Drive Lock HDD時所需的PASSWORD)，我拿A HDD 設了Drive Lock HDD ，再拿
B HDD 相互交換HDD PCB (PCB 上有DSP，MEMORY，ROM)，結果A HDD 換了B HDD 的
PCB 後，還是有Drive Lock ，代表PASSWORD 是寫到HDD 的磁軌，跟HDD PCB 沒有關係.
以上，希望對板主有幫助....

我想這些可以參考看看，希望有些幫助!!
This menu item is available only for drive, which support Security Mode feature set
(bit 1 of word 82). Next features are described in word 128. Maximum password length is
32 characters.
Drive Lock is based on the industry standard ATA-3 specification. The standard uses a
dual password structure featuring a User and Master password and defines two security
modes, High and Maximum. Under High mode, the Master password can be used to
unlock a protected hard drive and reset the User password. By contrast, in Maximum
mode the Master password can only be used to reformat the hard drive and reset
security options for the newly formatted drive.
In the Maximum mode, the Master password cannot be used to change the User
password without first reformatting the hard drive. This protects against unauthorized
access to hard drive by the owner of the Master password. In both security modes, if
both passwords are lost, the hard drive is rendered permanently unusable. The decision
to implement only the High mode was made to eliminate risk of data loss in the event
only the User password is lost.
In High security mode, one can unlock the disk with either the user or master
password by using the "SECURITY UNLOCK DEVICE" ATA command.
In Maximum security mode, one can not unlock the disk without knowing the
passwords. One way to reuse the disk is to issue the SECURITY ERASE PREPARE
command followed by SECURITY ERASE UNIT. However, The SECURITY ERASE UNIT
command will require the Master password and all data will be erased as a result.

其實這樣說是不正確的。
有鎖又有解！
解除這些跟進入手機的工程模式是類似。只要方法得當。
