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 USD 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.
* 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.
