   1) Under 2.0 I've yet to meet problems of HD not validating. Methinks
it's not as much of a problem as it used to.

   2) If you make a Swap: partition on the HD, it could actually be
formatted (Quick) at every boot! Even if the disk structure was completely
wrecked, who wouldd need to recover even a single byte off this partition?

   Using a Swap: partition solves this problem from the ground up, and also
avoids the potential problem of disk fragmentation on very loaded systems.

   So, VM is good for you.
