As a safety measure to prevent unwanted file loss,
use the Hard Disk Protection function to protect

tions on the Hard Disk, the protection must be
removed.
Select the Hard Disk Protection function and
press ENTER to activate the protection function.

HARD DISK BACKUP
This option allows you to backup part or all the
Hard disk data to floppy disk in compressed or
decompressed form. By default, the "Compress"
option is selected.
At the end of a work session, always remember
to copy all newly elaborated data present on Hard
disk to floppy disks. Should the Hard disk suffer
damage and data loss, you will always be able to
recuperate the data from disks.
How to back up your Hard Disk data
1. Have some empty formatted data disks ready.
As a general rule, 1000 Kb of Hard Disk data
are compressed to approx. 50% of the origi-
nal value in the case of Songs, and 30% in
the case of Sounds. Use this conversion to
calculate approximately how many disks you
will require to backup your data.
The size of each selected Block file is shown
at the bottom of the directory.
2. Select Hard Disk Backup and press ENTER to
activate the function.
Selecting this function opens a second level
display showing the Hard disk directory on
the left and a column on the right where you
can prepare a list of data to backup and com-
press.
The backup list can consist of Block files only,
not individual files normally found in a block.
