OK, cool. Glad it worked out. Having a box drop it's power or having
the underlying OS bail out on you is a little hard to deal with. Well,
you can deal with it easily if you don't want any performance (sync
writes to the disk for each update etc). Just a rule of thumb for the
future : if the OS didn't get a chance to flush it's kernel buffers
then there's a good chance any active indicies will be corrupted.

But, as you can see, it's easy enough to recreate them. I'm glad to be
able to make your day ;-)
