Best practice to reclaim the recovery partition?

[turnstyle]

Hi all, I'm hoping some folks here might have some suggestions on how to best reclaim the recovery partition.

I don't actually have a DVD burner, so I thought I might never get around to reclaiming the recovery partition.

But I just saw somebody mention using a 16GB USB flash drive instead of DVDs, and that sounds great to me.

Can I in fact save the revovery data to a USB flash drive, which I could then use to rebuild the machine? Presumably back to the state in which it originally had the recovery partition?

And once I have the recovery data on the USB drive, I can then get rid of the Lenovo Q: recovery partition, and reclaim that space back to my C: drive?

Thanks so much for any advice!

I just found this:

http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-74246

The doc doesn't list X220, but is this the correct procedure for X220 as well?

And the correct way to test the USB recovery drive is to try booting from it? And if it boots, I can then delete the built-in Q: recovery drive?

Thanks!
