Updated: rockbox nano 4gb 1st gen database problem

[GodEater]

Run chkdsf /f again.

Re-initialise your database.

Shutdown your ipod.

Turn it on again, see if the Database is ok.

Then try and play a tune.

I thought everything was fine. I was able to change themes see all the music in the database. however when i went to play a song i got a fatal error and had to reboot. Now it wants to reinitialize the database.

should i do the chkdsk, then restore, then reinstall rockbox to see what happens?

Hi Jpphun,

I am having exactly the same issue as you.  I also managed to get to that stage last night, where the database initialised but playing a song gave me a fatal error.  Does anyone know of an older build that will definetley work? Maybe we can try and find the problem, binary search??  

[amckinley03]

Ok,

I reformatted my ipod to factory settings using itunes.  Reinstalled the rockbox bootloader, and installed the latest version of rockbox of my nano, r14741-070918. I booted it up and tried to intialise the database with no music on the ipod.  

Unfortunatley it still doesnt work, the database hangs saying building database at 478 files.  I can still go back to the main rockbox menu but the database building has just stopped.  After a soft restart it still says database not ready.

Any ideas?

ok sorry to bump this topic but uhm i had the exact same problem, but i think it was because i reset the ipod(menu+center) when my database was initialised, so i tried holding play, and for some reason i had to initialise it again when i booted up so i did it and when i rebooted again, it was all there but then when i played a song, there were these weird background sounds(but you could still hear them clearly), and the song played just a wee bit too fast.. any reason for this? The rockbox.ipod file is still in the right place. I have no idea what that chkdsk or something stuff is so if i have to do that you'll have to explain i'm a noob in all of this stuff  

[Chronon]

chkdsk is a windows utility for checking (and repairing) the filesystem on a drive.  

For those with problems, can you build a database containing 2 properly tagged files?  (I'm actually not sure what normally happens when you try to build the database with 0 files on the player.)

Anyone posting in this thread please also provide which model of DAP you are using.

[AmbiquitY]

what is DAP? I'm telling you i'm a real noob   i'll delete all the songs and put 2 back on and reinstall the bootloader and stuff, hope it works

[Chronon]

DAP = Digital Audio Player

I don't think reinstalling the bootloader will matter.  Just try adding a small number of files first and see if it will build properly.

ok so i even recovered my ipod to start like completely over and i only put 2 songs on it, the database build properly, when i booted it initialised perfect i could see the 2 songs when then when i tried to play one i got an error :
Prefetch abort
at 41F10F74 (0)
I'll try rebooting...

EDIT: i rebooted (menu+select cause i couldnt do anything after the error) and now when i go to the database, there's the statusbar at the top and nothing else..

EDIT 2: (rebooted again) it all seemed to work fine, played a sond still worked, sound quality was bad but it worked, then i wanted to skip to the next song and i got an other error :
Undefined instruction
at 00ADBEF6 (0)

dont know what to do...

[Chronon]

What model is your iPod?  If it's a nano, then these problems may have something to do with the playback issues that a subset of 1st generation nanos seem to experience.

What do you mean by "sound quality was bad"?

[AmbiquitY]

nano 1G 2GB, and there was like alot of distortion on the music...  Would getting an older build help anything? if yes where can i find it cause i've got no idea

[Chronon]

You might be interested in FS#7510.  Maybe you are experiencing something similar.

I'm running r14986 now, somebody posted it there. Seems to work pretty well the only problem is still i put 3 songs on in in the beginning to test if it works, and it worked but there was only 1 song in the database...though if i plugged it back in in itunes i could see there were 3 songs.. oh well im gonna put more songs on it and see what happens..

EDIT: it worked!! everything now works like a charm
