Ondio FM Error "Save Failed No Partition?"

(1/4) > >>

dmilamj:
Greetings,

I'm getting a "Save Failed No Partition?" Error on my Ondio 128 FM. The error occurs whenever I change a setting (so I imagine it must be Rockbox trying to write the settings info to the settings area. ) Interestingly enough, the setting is changed after the error, but is not persistent after a power cycle. I also get the error when I play an mp3 file (occurs more or less continuously) but I seem to be able to record okay.

This happens with both 2.4 and the daily build from Jan 20th (both running from flash).  I have tried reformatting as FAT but that doesn't seem to do help anything.

Anyone have any suggestions?

Regards,

Dave

Okay, I'm replying to my own post but...

I've tried formatting with both Dos, Win 2k, and XP. Always FAT16. The "Save Failed No Partition?" error keeps coming up.

I was looking through the Debug menu and I came across the "partition info" menu. Huh. There are some strange partitioning things going on with this Ondio.

Ondio partition results:

P0: S: 6F727265
T:69 82367 MB

P3: S: 0
T: 0 1677301 MB

P2: S:A0D
T:74 0 MB

P1: S:656B2079
T:73 913028 MB

The same menu on my Recorder (I have a 10 gig drive in this recorder...it's a long story)

P0: S:3F
T:C 9590 MB
 
P1: S:0
T:0 0MB     (P2 and P3 are the same)

So, is this debug menu applicable for the Ondio? If so, there's some stange info written in the partition area of my Ondio.

Anyone know how I can take care of this wierd problem?

The file system is definitely not the problem. It looks like you accidentally formatted your Ondio in "superfloppy mode", i.e. the file system starts at the very beginning (sector 0) of the disk.

Usually flash cards and the Ondio itself are formatted like a hard disk, i.e. with a partition table. In this case there are some unused sectors (the rest of one track) between the partition table and the start of the file system. Rockbox uses one of these sectors for saving the configuration.

Since with superfloppy mode there is no room before the start of the file system, rockbox is unable to save the configuration, and gives you this message every time.

To get rid of it, you'll need to recreate a disk layout with a partition table somehow. This is very difficult to achieve with Windows. Back then when I was testing the various cases, I also formatted in superfloppy mode. To get back to the partitioned layout, I ended up rewriting the first track with a very lowlevel tool. If you have cygwin installed, I could provide instructions and a prepared track image file.

Jens, do I miss something? On the external MMC, we should be able to deal with superfloppy mode since we have multivolume. The space for the config sector is only needed at the internal memory.

Jens:

That must be it. I'm glad to hear that it's a fixable problem.

I do have both Cygwin and Linux available. Any help would be greatly appreciated.

Jorg:

This is for internal flash, so I think Jens has figured it exactly.

Regards,


Dave
