I want more room! (repartition from DeanGibson)

New NCs have a new partitioning scheme. Only 1G is left open to the user via their computer. If you have lots of apps or lots of video books, this is good.

This is bad - like, toxic - if your NC gets out of sync with the rest of your library. You can't manage the files that BN is storing the way you could under the earlier releases of 1.1 and 1.2.

Dean Gibson on the BN Nook Forums has released some great Clockwork Recovery scripts.

One will remove the accursed cookbook. Another, originally posted here:

will let you repartition your NC to have 5G of available onboard storage and manage your files again.

you will need:

- a microSD card
- a copy of the Clockwork Recovery disk image
- copies of both of Dean's zip files, from and
- a disk imaging tool such as diskimag (or use dd for mac/linux)
- a good zip tool - I recommend 7zip.

Leave Dean's files zipped.

The Clockwork Recovery disk image is available here

Download the file that matches the size of your SD card.

Dean's file is explained below. First, make the card:

Step 1: Make a bootable CWR disk.

Completely unpack the CWR file you downloaded. You must use a file whose name ends in .img. as your source for making the disk. The files I am pointing to for downloading end in .tar.gz, and are essentially "double compressed."

gz = gzip. 7Zip, an excellent cross-platform compression utility, can decompress these, leaving you with a file whose extenion is .tar

.tar = unix tape archive. 7Zip, an excellent cross-platform compression utility, can extract files from these.

Once you've unzipped and untarred the file, you should have an .img file (sized appropriately for your SD card. You will need at least a 256 M card, but I prefer to use larger cards so I can also store backups on them.)

Use an imaging program (diskimag or winimage or dd for mac or linux) to make a bootable SD card by "writing" the .img file to your SD card.

This erases all the data on that card.

The card is analogous to a bootable disk for your PC (remember boot floppies?) The program formats the card and write a very few files to it. Those files tell the Nook Color "you can boot from me. Once booted, run Clockwork Recovery."

After you make the disk, leave it mounted on your computer.

Copy both of the zip files onto your CWR card. Leave them zipped!

Safely remove the card from your computer. Power down your Nook Color and insert the CWR card. Power on, and you will boot into Clockwork Recovery, which is controlled using the volume and power buttons to go up and down in menus (volume) or back (power.) An action is chosen using the N button on your NC.

Now, here's Dean:
  1. Backup everything you wish to save, or archive it on the B&N site, because this will clear all your data on the device. The OS (whatever it is) will not be touched.
  2. Boot into ClockworkRecovery.
  3. Repartition back to B&N 1.1 partitioning:
  4. REBOOT into ClockworkRecovery.
  5. Reformat (and clear) /data, /cache, and /media after any partitioning:
  6. If you backed up and restored the B&N data, you should be able to restore and continue without reregistering, but don't count on it (you may have to reregister).
