I have 2GB SD card and a little problem with it.
- I can't delete directories from filemanager
- I can't delete dirs from terminal using "rm -rf"
All it says is 'read only filesystem'

I've tried also formatting it from filemanager's menu (and it seems it goes ok) but when i open card, everything is still there.

I've also tried to mount card on my desktop computer - iMac G5 - but it doesn't mount.

Is there anything else I can do, or should I just go and buy new card?

Thanks.
