Resize Nook STR Partitions

---

I wanted to increase the available space for my side loaded content and reduce the space for B&N downloads

First I used noogie to make a backup of the pristine nook at v 1.0.0, next I upgraded it to v1.0.1 and made another image

Then these commands on a linux box

dd if=/dev/zero of=new.img bs=1958739968 count=1

(
cat << _EOF
0,8,c,*
,2,c
,64,L
,,E
,128,L
,668,c
,32,L
,,L
_EOF
) | sfdisk -H128 -S32 -D -f new.img


kpartx -a mynookbackup.img
kpartx -a new.img

mkdir x z
cd x
mkdir boot  cache  data  factory  NOOK  p5  rom
cd ../z
mkdir boot  cache  data  factory  NOOK  p5  rom
cd ..

mkdosfs -H128 -t32 -F16 -n boot /dev/mapper/loop1p1
mkdosfs -H128 -t32 -F12 -n rom  /dev/mapper/loop1p2
mkdosfs -H128 -t32 -F32 -n NOOK /dev/mapper/loop1p6

mkfs.ext2 -L factory /dev/mapper/loop1p3
mkfs.ext2            /dev/mapper/loop1p5

mkfs.ext3 -L cache   /dev/mapper/loop1p7
mkfs.ext3 -L data    /dev/mapper/loop1p8


cd x
mount /dev/mapper/loop0p1 boot
mount /dev/mapper/loop0p2 rom
mount /dev/mapper/loop0p3 factory
mount /dev/mapper/loop0p5 p5
mount /dev/mapper/loop0p6 NOOK
mount /dev/mapper/loop0p7 cache
mount /dev/mapper/loop0p8 data


cd ../z
mount /dev/mapper/loop1p1 boot
mount /dev/mapper/loop1p2 rom
mount /dev/mapper/loop1p3 factory
mount /dev/mapper/loop1p5 p5
mount /dev/mapper/loop1p6 NOOK
mount /dev/mapper/loop1p7 cache
mount /dev/mapper/loop1p8 data
cd ..

rsync -avP x/ z/
sync
umount x/*
umount z/*

kpartx -d mynookbackup.img
kpartx -d new.img

after that I now have 1.4 GB for side loaded content.

Hope this helps someone.

Thanks for sharing. This is something that i have been wanting to do so I would not have to use an sd card.

Now I do have a question on this. the part

(
cat << _EOF
0,8,c,*
,2,c
,64,L
,,E
,128,L
,668,c
,32,L
,,L
_EOF
) | sfdisk -H128 -S32 -D -f new.img

what does this actually do?

It creates a new partition table on the file new.img using sfdisk I can script it instead of doing it manually

Here is the output of fdisk -l on both files

Thank you very much, it works very well

Here is what I did with comments of what I understood (might be useful for someone)

#First, we create a blank image (same size as the nook, mine is 1962934272)
#I used bs=1916928 count=1024 instead of bs=1962934272 count=1, I assume it is the same (or else I didn't have enough memory))
dd if=/dev/zero of=new.img bs=1916928 count=1024

#Then, we create partitions on it with sfdisk (I used a larger data partition to have more space for my apps)

For those of us tards who have no clue how to use linux and still wanna increase the size of our Nook Touch, is there a nice gui that will do the same thing?

Another helpful trick to add to this mix:

symlink /data/media to
/media so you can actually see the files BN is downloading to your device.

in adb shell or via ssh:

cd /data/media

rm -r *

cd ..

rmdir media

ln -s media /media

After doing this, the reader, etc. put their files where you can pick them up and archive them in Calibre, etc.

One more nook succesfully resized.

Thanks

is a step by step instruction possible......

Hi, I can see the you do not care about bootloader during the resize. Do you know what bootloader is used in nook? grub? (don't have my nook atm so I cannot check it)
