I'm not sure the powerpack will charge the battery, as it will supply less than 4.5 volts (4 x AA batteries). Nominal voltage for charging is 5v. It will power it but not charge it, or at least not significantly. I have used a 4.5v wall-wart in the past, and charging happened a bit, but certainly not a full charge. The battery backpack should show similar characteristincs to this. > 5. Yes, the disk cache will help, since you are powering off the hard > disk completely.

However if like me you play a lot and browse very little you will lose out. This is because the dircache consumes memory that could otherwise be used for cacheing music playback, thus your disk will spin up more often to load music data ready for playing. -- Mike Holden http://www.by-ang.com - the place to shop for all manner of hand crafted items, including Greetings Cards, Jewellery and GiftsReceived on 2006-10-18 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
