I: Jffs2 space problem ... Newly-erased block

["Calò Massimo" <m.calo@ctsgroup.it>]

Hi,

	I think that the problem with my partition is generated by an error
on erasing the flash(AM29LV160DB).

After the mount command

	/>mount -t jffs2 /dev/mtdblock5 /mnt

I receive the following msg:

	Newly-erased block contained wod xxxx at offset xxxx
	Newly-erased block contained wod xxxx at offset xxxx


Can someone help me on finding the cause of this messages?

Thanks!

	Massimo.

Hi all,

I eraseall the partition but if I do the df command I see that it is 100%
used ...?!?!?
