re: database refresh on a low battery. is it possible?

[gramps]

I have a sansa fuze v2 on rockbox for a while now.
my sansa fuze's battery is down to about 4 or 5 seconds of power.  For the last year or so, I have been refreshing the database by unpluging the fuze from my USB and plugging it back in to give it power for the refresh (takes about 3 or 4 minutes).
I have found the USB mode to be unstable and don't refreshing under rockbox firmware, as it freezes the player.

I wanted to know if it was possible to initiate the refresh of the database under the sandisk firmware while it is still plugged in.

I would replace the battery, but read that it is too difficult. 
thanks

But I'm thinking you already know this.  Are you saying USB charging is unstable for you?  How do you use it at all with 4 seconds of battery life w/o keeping it tethered?

[gramps]

not USB charging, but USB syncing is the issue under rockbox firmware.  i get the issue where you have to drain the battery overnight to get it responding again

My procedure for refreshing database with a 4 second battery life.
1. plug in USB which starts up original firmware.  sync new music/podcasts
2. unplug USB cable to initiate the refreshing database procedure.
3. plug USB cable back in within 2 seconds or so to power the player during refresh.
4. unplug USB just as the the refresh finishes so that the data does not put the player back into sync modem having to refresh it again.
5. plug player into non-data usb cable to use it.

unfortunatley as the battery slowly but surely almost dies, i cant accomplish taks #4, as the player takes a few seconds to respond to a request to refresh.

So you're asking at the Sandisk firmware rather than the Rockbox database?

[gramps]

its the only way i can get rockbox to run.
i only use sansa firmware to sync

Yes but the database refresh is for the sandisk firmware. If you're using Rockbox you don't need to build the original firmwares database because you aren't using it.

I haved the rockbox firmware for syncing, but I can't figure out how to sync my files (using automater) in OS X, stability.  After a minute or so, the player stops responding
Is there a more stable method? because i would use it if i could, and rid myself of the sansa firmware altogether.

[saratoga]

Its not entirely clear to me what you're asking, but I think the answer is to sync with the sandisk firmware and then reboot without unplugging USB so that the battery doesn't die. 

[gramps]

That is exactly what i am asking.  how do i do it, i can't figure it out.

Copy the files over, unmount the disk on your PC, and then hold power until the player reboots.
