FS#1305 - Q73: FAQ on recorder crash during USB upload

[See attachment for unmagled text :-)]

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.
