Clip Zip is semi-bricked! D:

[thejerwin]

I recently installed Rockbox on my Clip Zip, because the Sansa logo was freezing on the screen at startup. Now, in the stock firmware, I removed my Sandisk Micro SD while refreshing the media, and now the player will not boot past the Rockbox, or Sansa logo. Can anyone tell me how to fix this?

When player off - try hold select (middle button) and connect it to usb. Then try check disk for errors.


P.S. Somebody knows: is it possible add fsck.vfat to bootloader?

No.

Why? Not enough space for it?

[saratoga]

The bootloader on AMS devices is compressed into the patched firmware, so the maximum size is very limited.   How big would a file system check be?  It might not fit.

It's not really a question of size, at least not specifically.

It's more a question of doing things right, and that filesystem scanning really just doesn't belong deeply embedded in the bootloader or Rockbox core.

The page I linked to (maybe you didn't realize my response was actually a url?) does explain that no one would object to a scandisk plugin, but that would only be useful in a very specific set of circumstances. Specific enough to make it basically irrelevant.  You could pretty much only use it if the device had removable storage and it was the removable storage that was known to be corrupt.

How can you trust a scandisk tool to repair the storage volume it itself resides on? How can you know that it is itself intact?

There's also the question of efficiency. If you have a digital audio player, you have a host in order to transfer media to it (and install Rockbox with!), and that host is infinitely better suited to performing a filesystem scan/recovery than a DAP is.

Thats why I suggested add scandisk tool to bootloader.
But probably you right - we need it no too often.

In any case we have too many same post from users. It very bad user experience when player just freeze on boot. Probably we should add some more checks on boot to prevent this. And in case error show message something like "FS corrupted. Please connect usb and check disk for error.".

Another question: can we add sd card support in bootloader and boot from sd card when main disk not available?

The bootloader doesn't exist on the file system, so thats why you'd put the tool there.  But I'm not sure its feasible.

If you could detect that the file system was corrupted, yes you could do that, however most people wouldn't have a second rockbox install or even an SD card, so I'm not sure how useful it would be.  Detecting a bad file system might be better handled by telling the user to plug in USB and then automatically mounting the file system.

I mean another case - when main disk (flash) have hardware issue. In this case user can write rockbox to sd card and continue using player.

[saratoga]

Oh yes that could be done.  However, the bootloader is loaded from the main internal storage, so if the NAND is really bad the player may not work at all. 

[Mihail Zenkov]

AFAIK in most report about bricked sansa players bootloader still work but show 30MB flash drive.

[saratoga]

I think the 32 mb flash drive isn't actually on the nand though. Usually it contains nothing and cannot store data.

[Mihail Zenkov]

But bootloader still work, right?

[saratoga]

I'm not 100% sure, but I think if you get the 32MB empty partition the NAND is totally unresponsive, meaning no bootloader at all.

[Mihail Zenkov]

You right - system detect this flash drive as "SanDisk M200Plus", but bootloader should show "Rockbox Internal Storage".
