Utility Features
Updating Firmware
To update your unit's firmware, hold down the EJECT button, then power on the unit until it prompts you to
insert a firmware update CD. Then, follow the on-screen instructions. Certain steps in the update process take
several minutes to complete. Do not switch off the unit during the updating process unless prompted to do so.
After you update the firmware, be sure to recalibrate your unit through the UTILITY menu.
Calibrating the Unit
To calibrate the unit, press MENU, select UTILITY and choose CALIBRATION. Follow the instructions as shown
on the display.
Updating the Gracenote® Database
To make sure your HDX will display the correct track and title information for new CDs, you should periodically
update the Gracenote Music Recognition Database, stored on the hard drive of the HDX:
1. Download the updated Gracenote Database .zip file from the support section of www.numark.com,
and store it on your computer.
2. Connect the HDX to the computer via USB and power up the HDX.
3. Unzip the Gracenote .zip file to the root directory of the drive assigned to your HDX ("E:\" for
example). If asked to overwrite the existing Gracenote files, choose yes.
4. Once the file transfer is complete, disconnect your HDX from the computer.
Formatting Your Hard Drive
To format your hard drive, first obtain the newest firmware update, available in the support section of
Numark.com. Because the firmware update is in "disc image" format, you must make sure you burn the
firmware update CD by choosing the option in your burning software that allows you to create a CD from an
image file. Since every burning program is different, you may need to refer to your CD burning software
instructions to find out how to burn a CD from an image file.
Once you have created the firmware update CD, power up your HDX while holding the EJECT button. Insert
the firmware update CD when the HDX prompts you to do so. Once the HDX recognizes the disc as a firmware
update CD, select the "Install with Format" option. This will erase the entire contents of the hard drive,
inclding all of your audio files, playlists and the Gracenote database.
Installing a New Hard Drive
You may want to use a different hard drive with your HDX, or have the ability to swap drives in and out of the
unit. When inserting a new hard drive for the first time, follow this procedure:
1. Get the latest firmware update CD from the Numark website at www.numark.com.
2. With the HDX powered off, remove the platter, record, and record cap by unscrewing the spindle
clockwise (note, it is reverse-threaded!)
3. Unscrew the hard drive locking screw which is directly above the hard drive caddy.
4. Remove the old hard drive caddy from the unit by pulling it out gently.
5. Insert the new hard drive caddy.
6. Replace the hard drive locking screw.
7. Replace the platter, record, and cap by screwing the spindle on counterclockwise.
8. Power the HDX on.
9. Insert the update CD and wait for the upgrade to complete.
10. Turn off the HDX using the power button. When it is completely off, turn it back on again.
11. At this point you may want to follow the instructions above to install the Gracenote Music
Recognition Database.
Note: Never remove the drive from the unit while the power is on!
Recovering From a Corrupted File System or Damaged Hard Drive
In the unlikely event that information on your hard drive becomes corrupted, the unit might not complete the
boot-up process, or might appear to "hang" when you try to select a song. If this happens, try the following:
Connect the HDX to a computer via USB and run "checkdisk" on it. In Windows XP, you can do this by
right-clicking on the HDX drive and selecting Properties. Then click on the Tools tab and click the "Check
Now" button. This will attempt to fix the errors on your disc.
If that does not work:
Connect the HDX to a computer via USB and try to back up your music to your computer by copying the
contents of the audio folder from the HDX to your computer. Keep in mind that this folder may be very
large, so make sure you have enough free hard drive space on your computer. After you have backed up
your audio files to your computer, download the latest operating system from the Numark website and
burn an operating system disk.
Power on the HDX while holding the eject button. The HDX will prompt you to insert a firmware update
CD. Insert the firmware update disc and choose the "update with format" option. This will update or
reinstall the operating system and format the hard drive, erasing all files from the hard drive.
doing this, turn the HDX off, reconnect it to your computer via USB and try to copy the audio data back
to the HDX from your computer.
