1. Cabling – Often times, the cabling is not firmly 
connected. We recommend that you remove 
the drive from the cable, the cable from the DJ, 
reassemble and try again.
2. Master – Make sure that both drives connected to 
the Disk Jockey have been jumpered to “master” 
and not to “slave” or “master with slave present.” 
On very rare occasions we have seen success with 
the drives set to cable select. See the FAQ on the 
Diskology web page http://www.diskology.com/
djfaqs.html that discusses cables select for more 
information.
3. Drive size – this is a VERY common problem with 
the Disk Jockey; people try to copy one drive to a 
drive of the same exact size. Now, this often works 
without ANY problems (we actually copy like pairs 
in our lab, 2x40 GB, 2x60 GB, 2x120 GB, etc.) but 
with that said, we typically hear from customers 
that two drives of the same size will not work. 
Upon further investigation we have discovered that 
on occasion different drive manufacturers format 
a similar sized drive out to a different number 
of total sectors, for example, a WD 40 GB drive 
might format out to 46,000 sectors and a Maxtor 
40 GB might format out to 45,996 total sectors. 
If you try to copy the WD to the Maxtor the Disk 
Jockey will issue an audible beep because there 
are not enough total sectors to copy to. This can 
also be said with regard to same sized drives from 
the same manufacturer if they are different model
