The player is designed so that you can completely remove power from it at any time. You can pull the plug whenever you want, even if it's right in the middle of playing a song. When you apply power to the player again, it should pick up right where it left off.

Here's how it works:

  • When you select or shuffle a new playlist, it writes the current song running order onto a special area of the hard disk. This is the only time that the hard disk is mounted read-write while the player is in the car, and it is very brief. And it's designed so that even a power loss at this time would not harm the player. Otherwise, the hard disks are left in read-only mode at all times.

  • When the power is lost to the player (and I'm talking about complete power loss here, not just turning off the car's ignition), the player uses its last dying gasp of electricity to write its current position within the song running order into flash RAM. It also writes a few other useful things into flash, things related to the player's current "state".

  • When power is re-applied to the player, it re-reads the current running order from this special hard disk partition, then reads the entry from flash RAM to locate the proper position in this running order from which to begin playback.
There might be an occasional, very rare instance of the player forgetting its current position within the playlist. If that happens, it will seem to go back to its last-saved position from the previous power pull when power is re-applied. This should only happen once in a blue moon. I personally haven't seen this happen to my player in months. If it happens to you all the time, for instance, if it happens to you every time you turn off the car's ignition, please click here for information on how to fix it.

There may also be an indexing issue with Variable Bit Rate MP3 files, discussed here. However, this is totally unrelated to pulling the power.

The only time when it's dangerous to pull the power is when it's in the middle of a synchronization operation, or when you're hacking on the player's hard disk at the shell prompt and you've manually placed the disk drives into read-write mode. If you lose power at this time, you might corrupt the files that were being transferred at the time of the power loss. If so, those files would need to be sent to the player again, and then a disk check should be performed.
