================================================== ========================

as you can see. if I keep copying and deleting the same file
"Traumerei.wma" (~3Mbytes). the available space in mtdblock3 will
become smaller and smaller. finally, i can't even mkdir.

is it something wrong with my vivi ?kernel ? or busybox?

thanks.
