read only FS

[urodelo]

Hello.
I own a SanDisk Sansa c200 v2 (Rockbox utility 3.15) since a long time. Everything works but a week ago, after a lon time, I decided to delete the music files in the disk of the player (no sd card) and foound out that the whole FS is read only. I can't delete, upload, nor reinstall rockbox. I already chmodded the folder (which basically already showed the writing permission for my user), gone with sudo, changed usb port, voodoo, etc, no change. I don't have another pc where to try at the moment. Weird, because before I have been able to upload and delete the music files. Maybe a quite long time has passed and I forgot how to do... 😞 Any clue?
Thanks

Unfortunately in my experience (Clip+ at least) once the FS goes read-only its already too late,

Ive had several devices that wouldn't boot and I was able to dd pieces of a system image over and get back to working condition
but thats 2 out of probably 30?

now I have seen these devices go on to lead half way productive lives in the hands of a dedicated user like johnb
but for most that is too much to bear basically running a new version from the file browser every boot

Thanks for the answer. But I don't understand... What's the cause of the ro FS?

The flash memory wearing out and basically dying.

Oh... that's too bad... That player accompanied me during many many years through different moments of my life, it's very sad for me to know it is dying... 😢 The wheel already didn't work well but I could use it anyway. I hope maybe I can still use an SD card, if it doesn't interfere with the songs' db. Thank you all for the answers.

c200 doesn't have a wheel (just buttons), maybe you have e200?  If really a c200 could grab another off ebay as they're still around.

[urodelo]

Yes, it is E200v2. Dunno why the hell I wrote "C", I surely was half aslept. Sorry.

Sorry if I resume this old thread. I solved the problem, therefore I would like to post the solution, maybe it will be helpful for others.
I always use Ubuntu Linux to connect my e200 and, as I wrote before, one day the FS became read only. I still don't know why. However later I connected the player to a Windows virtual machine where the usb port was shared between host and guest. Well, Windows mounted automatically the e200 disk and it became writable again. Obviously you can try without a virtual machine, with a real Windows installation.

likely the dirty bit was just set do be careful about letting windows format the drives on some devices esp sansas
