Hi guys,

I installed build 17201. And it makes no sense having a 14 mb partition when you have a whole drive. So I too want to expand partition 3.

My problem is the same as others and I don't see the answer how do you handle resizing partition 3 when it is an unknow partition that you can neither mount/move/resize.

Thanks.


It appears to resize hda3/partition3 you first need to boot the system, maybe login to it root/admin is default login, before gparted/parted will pick up hd3 as an ext2. If you flash the dd-wrt image and run straight into gparted/parted hda3 will be unknown.

Absolutely correct. The detailed steps are:
* dd off part 4 into a file
* mount/copy off part 3's contents
* delete part 4, then part 3
* make new larger part3, leaving space for part4
* make part 4 (same size or slightly larger than old part4)
* mkfs.ext2 part3
* copy old part3 contents into new part3
* dd old part4 onto new part4


This worked fine for me using parted to delete/create part4 and resize part3 on Ubuntu.

After DD-WRT bootup, you need to remount part3 in rw to write to it.

mount -w -o remount /dev/discs/disc0/part3



IN what part I can insert that command for see the part?, how I can see that part (I using a cf disk 4gb)
