4). This mode will do a sector-by-sector compare to ensure
that the data was copied exactly from Drive1 to Drive2.
CAUTION – If during copying some abnormality occurs
or errors are detected a low frequency sound (a buzzer will
sound a low frequency buzz) will occur and then the power
LED will turn red. When this happens push on the blue
Power button for approximately 10 seconds and the Disk
Jockey will power off. It is a good idead to recheck the hard
disk drives using the standard mode.
MODE 4 (COMPARE MODE)
Mode 4 is the hard disk drive Compare mode. This mode
is typically used following a Disk Copy. In compare mode
two drives that have just completed the copy process are
attached to the Drive1 and Drive2 ports of the Disk Jockey
(if you have just completed the Disk Copy you can simply
flip the mode switch on the unit after powering down the
Disk Jockey) to Mode 4. The Disk Jockey then goes sector-
by-sector and compares the data written on both drives in
an effort to verify that the data written to the two drives is
identical down to the sector level. The same speed factors
that were discussed in the explanation of Mode 3 (Disk
Copy Mode) are still in affect with Mode 4, meaning that
drive size and speed are the largest factors of how long this
process will take. In Compare Mode the Disk Jockey IS
NOT connected to the computer.
