If you’ve used an SD card for more advanced purposes than simply storing digital photos (e.g. running a mobile or micro OS), you’ll find it requires a little more finesse than simply formatting the card to reclaim all the space. Read on as we show you how.

Good article. However, I don't see why you couldn't just use the Disk Management console to delete both partitions and create a new one encompassing the entire drive space. No need to use Diskpart (although that utility is very handy in instances where the GUI is not available).

Aaaah, of course it is possible on Windows. I had forgotten about diskpart, but it's nice to stay in touch. I'm not able to use Windows any more, but I like to stay in touch a little bit.

It (windows) wont let you delete the first partition, so you cannot do it through disk management.
I was looking for this a week ago, ended up using the RaspBMC installed to reset the SD card, another option if that is what caused the problem in the first place.

Hmm... didn't know that. Thanks!

Let's flip this question 180° - Now that you have it back to the original, how would you create the format that RaspBMC did? Can DISKPART do that?

All right guys. I admit I need some help. So I some how partitioned my 8gb SD card down to like 117mb... I tried using easeus and tried the diskpart you suggested with no results. it still showed the 117mb and says I need to format when I click on it. Any idea what the prob is.

Thank you for these instructions. I was able to get my 4GB card back to full capacity because of this.
