Q73: Help! My recorder crashes when I copy files to it!

A73: Yes, the recorder can crash when you copy several
gigabytes of
files to it. The explanation is simple: Copying
several gigabytes
of files through USB requires a long period of
sustained disk
activity and drains more power than the batteries
of the recorder
can store. A long copy will eventually drain the
batteries to the
point where the recorder can no longer function
and it halts.
This even happens when connected to the charger,
since the power
drain is more than the charger can provide! If the
recorder halts
while connecter to the charger, the batteries will
recover and
after a short while it will reboot the Archos
firmware in charger
mode. To make it worse, depending on the USB
drivers of your
system it can cause your system to crash as well,
or confuse it
to the point it needs a reboot.

There is no solution, just some tips.

* Connect to the charger when copying lots of
files. This will
not prevent the problem, but it will take longer
to happen.
* Make sure you have "Deep Discharge" disabled.
* Switch off the "Backlight On When Plugged" option.
* Use USB 2.0. Transfers will be much faster.
* Copy incrementally. With fully charged standard
batteries it
should be capable of sustained copying for 2 -
2.5 hours.
