[Barnes & Noble Nook Tablet] tselling:
Since I had a second NT to repartition, I wrote up the how I did it this time. Hopefully it is useful to someone. USE AT YOUR OWN RISK. You are responsible if you mess up your tablet.

Repartitioning your Nook Tablet requires ADB drivers on your PC and CWM installed either to EMMC or SDCARD. Here, I resized my userdata partition to approximately 4GB and my media partition to approximately 9GB. NOTE: ONLY MESS WITH Partitions 10 & 11 (media and userdata). I assume you know or can lookup how to install and use CWM and adb.

Parted complains about the partition table.... I let it fix the two errors. I don't know if that is good or not but hasn't seemed to hurt my NT. I think you can just ignore the errors... but they are very annoying throughout the process, if you don't fix them.

Install CWM either SDCARD or EMMC. Make sure you can use adb to connect to your Nook Tablet. If not, fix that first. Boot into CWM. In CWM mount /data and /sdcard and do a backup so you can restore /data since we are going to delete and recreate it. After the backup, unmount /data.

Use "adb shell" while CWM is running on the Nook Tablet and the USB cable is plugged in.

Note: Once done with the the resizing, have CWM reboot back to recovery (advanced option) and restore your /data partition data. Then reboot your system.

Here is a quick summary: Start parted on mmcblk0 from adb shell. Fix the errors. Delete partition 11 (userdata). Resize partition 10 (media) to make it larger... use the original start position and change the end position to make it the size you want. Recreate partition 11... use the end position from partition 10 as the new start position and use the original end position. Name partition 11 "userdata". Print the partition table along the way to make sure that its what you want. Exit parted. Use tune2fs and e2fsck to convert the ext2 partition back to an ext4 partition. Reboot back into CWM, restore your data partition and then reboot.

The commands I used while in the adb shell, along with the responses are below. Note that the bold text is the prompt and commands. The non-bold parts are screen output.

Error: The backup GPT table is not at the end of the disk, as it should be.

This might mean that another operating system believes the disk is smaller.

Fix, by moving the backup to the end (and removing the old backup)?
