Post-root sd card only 39m?

---

Ok, so I got an 8g sd card for my nook. It was blank so I didn't do anything to back it up. After writing the nooter image to it, it shows up as a 39m disk, and the windows disk utilities won't reformat it to 8g. How are other people doing it?

I used the following software: partition-tool.com/personal.htm

It is free for home use.

I used a partition software like JoshMiers did, but somewhere on here under the android development section other people were just using the NC itself. Remove the SD card, boot up the NC, put back in the SD card, then unmount and format the SD card.

OK got this solved. Here's what I did:

- Put the sd card into the nook & go to an adb shell
- `mount` to get the device file for the sd card. Mine was at /dev/block//vold/179:17
- unmount /sdcard
- `dd if=/dev/zero of=/dev/block//vold/179:17 bs=1024 count=2` to wipe the header
- Insert into a windows machine and format

It's all good after that.

or just put it into the nook and go to settings>device info>sd card> unmount, then format from the same screen

You can also use diskpart in windows to fix the sd card.

If your running windows 7 you should have it.

Yeah I was kinda irked at this as well. Diskpart fixed it up right quick and in a hurry. Amusingly enough I bought this thing specifically to read the Windows 7 Admin guide and happened to come across the info about diskpart for USB installs of Win 7, helped out quite nicely.

OK... Since nobody else has posted this, I will...

The reason that your SD shows up as 40M (no matter what its physical size) after going through the nooter rooting process is:

The .img file that you dd to your SD card writes not only the data on the SD card but also the partition table. The partition in the nooter .img file is ~40M in size. The Nook Color doesn't look at the physical device but rather the partitions on the device. Since the partition is ~40M, that's what shows up.

Just FYI... Android == Linux. Embrace your inner n3rd.

I'd rather use both. Anything Linux based I can load up in VMware and use. Of course I have a vested business interest in MS, they help pay the bills at the very least.
