• Selecting "All Data" will preserve the data that has already been saved to the hard drive. (If
"Format All Data" is selected, all user data saved to the hard drive up to that point will be erased).
Immediately after encryption is enabled, the encryption setting process will take several minutes to
complete before you can begin using the machine.
• If encryption is enabled after data has been stored on the disk, or of the encryption key is changed,
this process can take up to three and a half hours or more.
The machine cannot be operated while data is being encrypted.
Once the encryption process begins, it cannot be stopped.
Make sure that the machine's main power is not turned off while the encryption process is in progress.
If the machine's main power is turned off while the encryption process is in progress, the hard disk will be
damaged and all data on it will be unusable.
Print encryption key and keep the encryption key (which is printed as a paper sheet).
