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. -- cgit v1.2.3
