1. The speed of the copy is dependant on several

factors including: spindle speed of the hard disk

drives, both the master disk and the target disk.

Naturally a 5400 RPM hard disk drive copying

to another 5400 RPM hard disk drive will be

signiﬁcantly slower than two 10,000 RPM hard

disk drives copying data from one to the other. If

you are copying from a 5400 RPM hard disk drive

to a 10,000 RPM hard disk drive, or vise versa, the

speed of the copy will be dependant upon the lowest

common denominator of drive, in this case the 5400

RPM drive.

2. The size of a drive will also affect the speed of the

copy. The Disk Jockey must copy EVERY sector

on the hard disk drive as some hidden or invisible

ﬁles can be written to different areas of the disk.

Therefore, if you have 2 GB of data on an 80 GB

drive the Disk Jockey will copy every sector of

the 80 GB drive to the new target drive. For a

benchmark the speed of a 40 GB drive copy is

approximately 20 minutes, or roughly 2 GB/min.

1. Both hard disk drives need to be ultra DMA

compatible.

3. The “copy to” hard disk drive (on Drive Port 2)

needs to be equal to or greater than the capacity

of the hard disk drive attached to the Drive 1 port.

Even though, for instance, both disk drives are

listed as 40 GB by the manufacturer, sometimes the

formatted capacity could be slightly different.

4. If a larger drive is attached to the Drive2 port the
