A Volume Map error is a bad thing for most computers. Mine got one and it took down my machine for the last few days. I don't think I lost any data, but I'm sure glad I had split my hard drive into two partitions *and* installed a minimum system folder on the second. My second partition came up and ran just fine, allowing me to use Data Rescue, and move most of my first partition to my second partition.

So I seem to be up and running again, with a full backup burned to disc. Whew.
