Hi,

I am new here. Just installed the latest build for WNDR4300

DD-WRT v24-sp2 (04/15/13) std
(SVN revision 21286)

After installation, I found that the status page on space usage section shows:

NVRAM26.20 KB / 64 KB
CIFS(Not mounted)
JFFS217.00 MB / 17.00 MB

As I know according to the specification of WNDR4300, the flash memory is 128MB, but the JFFS only used 17MB.

Can anyone help out find it why?

Thank you

This is still an issue on build 22118. Any ideas on a fix for this? Step-by-step or a script to use via telnet/ssh... Thanks much.

Edit: Apparently 'Submit' and 'Preview' are too close together for me...

I did not proceed as

"...know the correct block size of your flash chip !!! be careful !!!"

concerns me greatly. I love this new router and don't want a brick.
