Welcome to the Diskology Disk Jockey support request page. At the bottom of this page you will find a support form that will go directly to Diskology support personnel eagerly waiting to help. However, before submitting your request for support, we ask that you read over the following common issues discovered when using the Disk Jockey. The majority of problems can be solved following the troubleshooting steps below.

In addition, please visit the the Disk Jockey Support FAQs.

1. My Disk Jockey is Beeping!
As you can read in your manual, the Disk Jockey (DJ) emits audible beep signals to let you know that there is a problem with either the drive you are trying to copy from, copy to or with the configuration itself (i.e. not using a UDMA drive, something that is not supported by the Disk Jockey).

If you are experience beeps with your DJ the most likely reason is that the drive you are copying to or from contains bad sectors. The DJ at this time is unable to skip severely damaged sectors of a hard disk drive. We will retry a bad sector 32 times before giving up the process and emitting the beep signal. If you believe that this may be your problem we recommend that you switch the Disk Jockey to mode 5, disk check mode. Attach one drive to the Drive1 port of the DJ and run a mode 5 disk check on the drive. If that works, try your destination drive. If either process ends in beeping it most likely means that your drive has damaged sectors. While we have not tested this product in house, we have had customers report success running a disk repair utility like GRC’s SpinRite ( to clear up the bad areas of the disk before trying a copy again. Know, however, that in a forensic environment this WILL change the hash value of a disk from its original state so please proceed with caution.

This process may also be used to verify if a cable is damaged. If you run a mode 5 disk check successfully with one cable and then try another and it results in beeping, it could mean that one of your cables is defective.

2. I have having trouble copying SATA drives.
There are a couple of items that frequently lead to questions when copying SATA. In addition to the information above on bad sectors, you may run into an audible alarm (beeping) immediately when copying a SATA drive. Make sure that you also have the SATA power cable connected from the SATA adapter to the Disk Jockey. Without the power cable connected the DJ will emit the audible alarm as to the DJ it appears that no drives are attached without power.

In addition, there is an issue with the red progress LEDs when using the SATA adapter. When copying from SATA to SATA using the Disk Jockey with the Addonics SATA adapters, the green power LED will begin to blink after pressing the start button the second time, but the red LEDs near the cable connectors that typically show disk access, will not be lit.  In this case, the green power LED can be used for progress status. Remember, the DJ copies drives at roughly 2 GB/minute.

3. Same-sized Drives and Drive Size Differences
Unfortunately not all similar sized drives are created equally. The DJ copies EVERY sector on a disk. So, if you have a 250 GB drive from Maxtor for example and let's say it formats out to 242.7 GB. Then you get a WD 250 GB drive and it formats out to 242.6 GB, you won't be able to copy the Maxtor to the WD because the Disk Jockey will notice right away that there are not enough formatted free sectors on the target drive. Then you'll get beeping. The other way would work fine, however. We typically recommend copying to a slightly larger drive. THIS CAN ALSO BE FOUND WITH SAME SIZED DRIVES FROM THE SAME MANUFACTURER. We often test with similar sized drives, however we have run into occasions where two same-sized drives from a similar manufacturer can run into copy problems. When in doubt please try copying to a larger drive before contacting support.

4. Example of a drive copy
Examples of how to copy a drive can be found in the downloadable manual as well as the downloadable DJ IT Quickstart guide located to your right. We will also provide this information below for your convenience.

Let us take you through an example using the most popular DJ mode, mode 3, or Copy Mode. Note – All modes that don’t require a computer operate in the way described below. So if you are looking to copy (Mode 3),  compare (4), disk check (5) or erase data via either a one-pass or three-pass erase mode (6 or 7) the following instructions will help you complete the task.

Step 1: Using the small screwdriver switch the DJ to Mode 3 (or 4, 5, 6 or 7 depending on desired results) on the Mode Switch dial.

Step 2: Attach the drive that you wish to copy data from (source) to port 1 of the DJ. There is an arrow showing data copy flow on the DJ as well.

Step 3: Attach the drive that you wish to copy to (target) to port 2 of the DJ.

Step 4: Hook up the power to the DJ (and plug it into the wall while you’re at it!)

Step 5: Press the Blue power button on the DJ one time. You should hear the drives start spinning up.

Step 6: After waiting a few seconds (typically no more than 5-10 seconds) press the Blue power button again, the copy process should begin.

Step 7: Go surf the web, answer some email, etc. The progress of the copy can be deciphered using the LEDs per the notes in the manual, but you can typically count on a copy of about 2 GB/min (actually a little less). So if you are copying a 40 GB drive, the entire process should take between 18-20 minutes. When the copy is complete the DJ will automatically power down the drives and shut off.

NOTE – If you run into a problem with the DJ and need to power the unit down, hold down the Blue power button for approximately 10 seconds and you will hear the drives spin down and the power turn off.

5. Pressing the Blue Button and nothing happens?
Occasionally we receive support requests claiming that someone has everything set up correctly for a drive, they press the blue button once, hear the drives spin up, press the blue button again and nothing happens? Try pressing the blue button firmly the second time and hold it down for a second or two. Often a quick press of the button on the second press will not result in the desired action.
