H10 Rockbox uninstalation

[Pavulon]

Hello,

I've uninstalled Rockbox as decribed on wiki page from my H10 5GB UMS. Then I also formated hard drive and installed original firmware (2.53). After that I've installed Rockbox again and... my custom settings (language, background and foreground color) were the same as in my old installation. Where are the settings stored?? Am I not able to really completely remove Rockbox without a trace??

Best regards,
Pawel

Before today they were stored in an otherwise unused sector on the harddisk, but with a current svn build just delet the .rockbox/config.cfg and they'll be gone.
The settings sector is never used by anything else an will not harm your player in any way but can of course be erased by directly acessing the disk with special programs.
