Security Measures
When you do not want the data on the hard disk to be read/written
When the Hard Disk Lock is set to [Enable], it is impossible to read/write data from/to
the hard disk when the hard disk is installed in a different computer, since a password is
also set for the hard disk. When the hard disk is returned to the original computer, you
can read and write data as before. In this case, however, make the settings in the Setup
Utility exactly the same as they were before the hard disk was removed.
It is possible to set the Hard Disk Lock even if [Password on boot] is set to [Disable], but
we recommend that [Password on boot] be set to [Enable] for security reasons.
(Note that this Hard Disk Lock does not guarantee complete protection of data.)
In the default setting, [Hard Disk Lock] is set to [Disable].
NOTE
You cannot set the [Hard Disk Lock] without setting the Supervisor Password. Set
the Supervisor Password if you have not done so. (
