Sansa clip v1 crashed

[brightRed]

Hello
Sorry if its wrong section im writing in, but i couldnt find any better. If its wrong, please move my thread - thanks.

I need help with my sansa clip v1. I just bought it week or two ago and im running rockbox all the time. Its stable version, and everything was ok just like 2 times i had strange errors in the middle of listening to song and my sansa was restarting. It was just 2 times so i didnt even do anything with that until today. I got error again (sorry but it turned off after few sec so i dont remember what was that error) and my sansa restarted. It was running ok, but all my songs disappeared. I plugged my sansa to computer and i saw that some my folders disappeard and some others changed their names to some strange. Every files were messed up (but whats strange rockbox was still running OK). Its strange even it was almost empty i got just 1 GB of free memory on my 2 GB sansa without any big files or music on it. I uninstalled rocbox with rockbox utility and installed again, but there is still 1 GB of memory missing and folders are still messed up and not like before the crash. I dont know what to do, because i got this sansa for 2 weeks and dont know anything about it or how to reapir this.
Sorry for my poor english and thanks for any reply or help

By your explanation, it sounds like your Sansa has a damaged file system.  You should connect it to your computer and scan the file system for errors.
