Sandisk USB Problems - database refreshing

[havic]

Hello All,  I have installed the rockbox bootloader on my sansa e270 6gb with the v0.2 sansapatcher with 3 different version of the sansa firmware (they are PP5022.mi4, 1.02.15a.mi4, and 1.02.18a.mi4) After I install and run rockbox everything seems ok.  I boot into the original firmware for usb support and it works for about a day or so.  Then for some reason I try to boot into the original firmware for usb support and  the original firmware say database refreshing and half way through crashes and the screen gets fuzzy.  I have to reinstall the original firmware and re-patch for rockbox support.

I have seen some posts on this problem before but no reason why or solution. Does anyone know if this is a Sansa problem or a patched firmware problem?  Any help would be appreciated. Thanks

I have seen posts on various forums hinting toward it being a problem with corrupt data somewhere on the player which is being read by the database, which causes a kernel panic, bringing the player down.  I know it is a little extreme, but you might want to try taking the contents of the player and copying them to your computer, deleting everything from the player (don't format).  Then reboot into the original firmware and see if it still does this.  If it doesn't then you know where your problem is, and you must find the source of the data corruption.  This is all speculation on my part, as I have to date not seen this to be confirmed to be the cause of this problem, but it is worth trying.
If it is data corruption, and the source is your music, then you can probably get around this by re-encoding everything in a format which is not supported by the original firmware, such as ogg vorbis.  The database doesn't seem to see these unsupported files and just skips past them.  Good luck.

What's strange here is that you actually never re-install the OF just the original boot loader (right?).  Also if the OF complains about data base corruption, this should happen even without rockbox.  I've noticed that the OF will rescan the database anytime I change ANYTHING on the flash, including WPS files, BMP files, etc....

Hi there. I'm sort of having the same issue, except without the crash in the OFW. It's just rather annoying that every time I boot up into the OFW after running Rockbox for a while to transfer stuff over USB, that it'll rescan everything. I'm guessing that whenever it sees a change in the used space of the drive it'll do this?

Pray for a quick release of the Rockbox USB code then, which will make booting into the OF an unecessary step.

I've looked around, but haven't found a post or a wiki page that gives a good outlook on where USB is with Rockbox on the e200 and some kind of time line. Any chance you could hint me in?

That's because we never post timelines.

Zagor is working on it currently, and it may be a week away, or it may be a year away. It all depends on stuff that's impossible to estimate. The best way to get a feel for current development is to hang out in IRC and listen to what's going on there.
