I'm trying to reinstall my Asus Transformer TF101 with Cyanogenmod, I select the "wipe data/factory reset" option in the ClockworkMod Recovery menu, but after installing it I find that the original directories remain in '/sdcard' (I expected them to be removed).
Is it safety if I delete this whole directory just by "rm -rf /sdcard" in the shell?
Thank you very much.
