To copy the entire contents of one disc onto another disc. There are two
procedures: one for a system with one disc drive unit and one for a
system with two or more disc drive units.
I N S T R U C T I O N
For one disc drive
1. Insert the disc you are going to copy
from,
in the drive unit. Then
type in:
!BACKUP <drive no.> TO <drive no.>
Note: In this case both the drive numbers are the same.
2. Data will now start to be read from the disc and put into a specially
reserved area of computer memory known as the buffer. The buffer can
only take so much data, and when it is full, no more data is read from
the disc, at this stage the message insert target disc is displayed.
3. Now remove the system disc and insert your blank disc. The data in
the buffer is now written onto the disc, and when it is all written, the
message
insert source disc
is displayed on the monitor.
Keep alternately inserting the 'system' (source) and ' b a c k u p ' (target)
discs until a message appears, telling you that the entire disc has now
been copied.
Do not forget to remove your backup disc, label it correctly and store it.
For systems with more than one disc drive unit.
1. Insert the disc to be copied from and the disc to be copied to, into any
two disc drives. R e m e m b e r which drives they are in or you could end up
copying the wrong way round in which case the data will be lost!
2. Type in:
