    I'm trying to use the Lion Recovery Disk Assistant and I get the following error:

    "The Recovery HD on this computer is damaged or not present. Recovery Disk Assistant requires a functioning Lion Receovery HD to create an external Lion Recovery"

    I'm using a MacBook Air that came pre-installed with Lion, but has had the second/most-recent version of 10.7.2 applied, for use with iCloud + iOS 5. Would this be the issue?

    I've properly formatted the USB drive as per the instructions.

    Any help would be much appreciated.

    It just occurred to me that I've restored from a Time Machine backup. Perhaps that kills the recovery partition?

    It should not, it's a separate partition. Sometimes things break. Check the partition for errors and maybe that will fix it.

    I've read that some new Lion machines (not all) have a built-in recovery partition or something like that, which doesn't reside on the hard drive. That's what allows "internet restore" or whatever it's called to restore the system to a totally empty hard drive without the need of any external media. Maybe that's your case, and you don't need to create external media, and you don't have a recovery partition on your hard drive. But I'm really not sure about whether this is the case!

    Since the current MacBook Air has this functionality built into it (Internet Recovery), isn't making a Lion Recovery Disk a moot point.

    So Internet recovery is the built-in recovery that baryon was referring to. I didn't realize that related only to specific (new) hardware. I have some reading to do.

    I think baryon just was speaking of the July 2011 MacBook Airs. If you can't use the recovery partition the machine defaults into internet recovery and downloads Lion from Apple. http://support.apple.com/kb/HT4718

    You can force the MBA into Lion Internet Recovery mode by starting up with cmd-opt-R.

    That's what confused me. The wording seems to imply that Internet recovery is an option for new machines (I have a 2011 MBA) if the Recovery HD isn't available, rather than just saying these machines don't have a Recovery HD. Maybe I'm just interpreting it badly and that does seem to be the case.

    Only the July 2011 MacBook Air and Mini have internet recovery. New machines in the future will feature it as well. The rest of us have to use the regular recovery partition.

    I believe that in addition to the Lion Internet Recovery that the MacBook Air and the Mac mini (mid-2011) also have a Restore Partition. The Lion Internet Recovery is used when the boot drive (along with the Restore Partition) is borked.

    :apple: Apple - OS X Lion Recovery - Introducing Lion Recovery

    This Macworld review of the mid-2011 Mac mini also mentions both.
