nano troubles

[lice]

so i installed rockbox on my video about 2weeks ago and was very happy with it. a freind of mine saw it and wanted it on his nano. after i installed todays build and bootloader, i restarted the ipod and initialized the database and it sat for about 10 secs and told me to reboot. this looked odd because it told me it had 3500 songs, and he only had about 40 songs.so i rebooted and went back into the database and it wanted me to initialize again. so i connected it to my computer and noticed that in the .rockbox folder there are about 7 strange files that just popped up. they've all got odd names and file extensions, some not even using standard characters because the little square box is mixed in. any help?

edit. these files cannot be deleted by either windows or stompsoft file shredder. weird

It sounds like file system corruption.  Try running chkdsk /f on the nano to see if it can repair any errors.

ran chkdsk and downloaded fresh boot installer, all is fine. thanks!
also downloaded utility v1.0.3 don't know if it made a difference but it doesn't lock up as much

edit: ok typed too soon. all music files are damaged and have terrible quality. i'll go out on a limb and say he has disk problems. it makes me wonder though, in the original iPod part of the system the files are fine. bad codecs? ipod wizard didnt work for any nanos i tried, maybe i just have bad luck with nanos.

When copying files to a device you connect over USB, when you're done copying, you NEED to make sure you choose to "Safely eject hardware" before you remove the USB cable, or you'll get this sort of issue. iTunes kind of does this for with its nice big "Eject" button - but when you're not using iTunes, you need to be sure to use the icon way down in the system tray.

I have similar issues. When I first install rockbox (before an initial reboot) everything is fine, USB speed is great, I disconnect and try the track I copied across and it sounds fine.

However after a proper reboot when I plug it back in, any file operations take an absolute age and the files are corrupted and full of glitches.

How can this be when as a normal iPod it's fine?

I also can't safely dismount the drive, it says it can't be stopped even tho nothing is accessing it.

I think something is screwed with the filesystem part of rockbox for some 1st gen nanos....I'm happy to help debug if someone can tell me what I need to do.

You need to keep trying. If the computer tells you it can't be stopped it's because something is still accessing it. If you unplug it whilst the computer is telling you this, then you WILL get file corruption.

They use the same filesystem as every other Rockbox target. What *is* known about Nanos is that Apple's emergency disk mode (which is what Rockbox boots into when you plug in the USB cable) is orders of magnitude slower than the disk mode you get when you're running the original firmware. For this reason a lot of Nano owners choose to boot into the original firmware before they copy over data. This means the transfer goes a lot quicker, and they are less likely to lose their patience when trying to safely eject the hardware, and therefore also less likely to get file system corruption.

Hopefully these issues will go away when Rockbox has it's own USB Mass Storage mode on PortalPlayer targets, and we won't have to rely on Apple's super slow disk mode.

Hey, thanks for the reply All seems to be ok at the moment...I used to get the corruption but it seems to be ok now.
