DiskWarrior is not an Apple product. I is also not a component of Mac OS X 10.7. I suggest you try checking the DiskWarrior tech support page at http://www.alsoft.com/diskwarrior/support.html for guidence.

You must have DiskWarrior v 4.4 in order to run under Lion. That does not mean you can't use an earlier version of DW if you are running a copy while booted in an earlier version of OSX provided that the version of DW is supported by that earlier version of OSX. So, you could use DW 4.3 on a Lion startup drive provided that you are booted into Snow Leopard or older, if that makes sense. Also, as of a few days ago Alsoft still didn't have a bootable CD/DVD for Lion, apparently they are waiting for a copy of the code from Apple to do this. So you can't boot a computer requiring Lion from an existing DiskWarrior CD or DVD (yet).
I seem to remember a memory error similar to what you are getting when there is not enough room left on the drive for virtual memory while DW works. The larger the drive you are working on the more virtual memory space you need. Remember that DW operates in a fail safe mode, that is, it writes potential changes to unused space on the drive first so you can use the preview function before committing to the final writing of the repalcement directory. How much free space unused room do you have left on these drives, and how big are they? I'm not sure if the free space has to be contiguous, if so you might consider iDefrag or something similar. However, as to any drive that already has problems, do not try iDefrag, that well might make the problem worse:(
I hope these comments help. - Randy

Thanks for the reply. The one external drive that prompts the error has ~200GB used and almost 800GB available. The other external I'm trying to rebuild has ~80GB used and over 900GB available. The internal drive of the iMac from which I am atempting the rebuilds has almost 70GB used and over 400GB available.
DW has since successfully rebuilt the internal drive (including just today) without issue, still not the two externals though.
Does any of this help?

It appears DW struggles with TM volumes. There are multiple results if you Google for timemachine + 2154.
I've personally also had no success attempting to repair TM volumes with DW.

I had the same issue. After DW said "hardware failure", I killed the fsck_hfs process that was keeping the disk busy and then DW was able to attempt the repair. But then, I got the out of memory error. After that, I ran Disk Utility repair again, and it worked!

This solved it for me
