7.7 Formatting the hard disk
You can delete all contents stored in the hard disk drive by
formatting it. If you wish to do that, select the Installation >
Format Hard Disk
menu, then you are asked for confirmation.
If you select Yes, formatting will start.
CAUTION
Formatting the hard disk will delete all files permanently.
NOTE
If a new hard disk drive is installed, it must be formatted
because the file system of the digital receiver is different from
any of the personal computer. You can neither record nor use
time shift with an unformatted hard disk.
