Troubleshooting
Unit will not power up
Make sure the power cable is connected and power is being supplied to the unit. Make sure there is a hard
drive in the unit.
“HD Not Detected” message appear on power up
Make sure there is a drive in the unit. If there is a drive in the unit, shut the unti down, remove and re-insert
the drive to make sure it is connected properly.
Unit gets stuck in the “Importing” or “Checking Filesystem” stage of bootup
Please note that it can take significant time to import huge amounts of music into the HDX’s database. As a
reference, importing 5,000 tracks may take up to 15 minutes to complete. Additionally, if the HDX is shut
down by means other than the HDX power switch (i.e. an outlet strip), the entire filesystem must be checked
for corruption. On a full 80G disk, this may take up to 15 minutes. Assuming you have waited a reasonable
amount of time, here are a few possibilities to consider:
The HDX operating system requires that there is at least 100MB free on the harddisk. The HDX can hang if this
requirement is not met. If this situation occurs, remove some music from the harddisk via USB and reboot.
Another possibility is that the system directory on your disk could be damaged due to abrupt poweroff during
disk activity. See “Recovering From a Corrupted File System Directory” for more information.

The file system directory on your disk could be damaged due to abrupt poweroff during disk activity. See
“Recovering From a Corrupted File System Directory”.
There are gaps or glitches in the audio playback
Some commercially-available CD’s are copy-protected. This means the manufacturer has intentionally inserted
a large number of errors on the disc, which makes it hard to play back on a computer, while fine to play back
on a regular CD player. This could interfere with the HDX’s ability to play or rip these files.
If the TOC (Table of Contents) has not yet been generated for the WMA or VBR MP3 file that you are playing,
glitches may occur during playback. Rip these songs onto your hard drive and wait for the unit to generate
TOCs for these as a background process before playing them.
Error messages or crashes during ripping or encoding
If you see a high number of error messages or the unit crashes frequently, the files or database on the hard
drive may be damaged or corrupted. This could be caused by errors due to improper shutdown of the HDX. It
is very important that you always use the power button on the HDX to shut down the unit.
Do not pull the plug out of of the wall or use any external outlet strips to turn the unit off.
If the information on the hard drive appears to be corrupted, the best way to try to fix it is to connect the HDX
to a computer, back up the audio files to your computer and reformat the HDX drive using the process
described on the “Utility Features” page of this manual.
A CD is stuck in the unit
If a CD is stuck and will not eject when you press the EJECT button, power off the unit, and unplug the power
cable. You’ll need a special tool which looks like flat-head a screwdriver with two prongs (Philips ECG part
number CR1833T, transport adjustment tool). On the bottom of the unit there is an access hole under the CD
player (next to the bar code label). Insert the tool and turn it clockwise. It will take a few dozen turns to fully
eject a disc.
