Thanks for the reply.
I did read that section of the FAQ and I had considered it. I still may
give it a try.
The reason I havent tried it was because I considered it more of a
desperate measure. That is, I hopeful that I would find an safer
alternative. Given the fact that I am in So. California and we are in the
midst of an energy shortage which will definitely produce rolling blackouts
this summer and the fact that the isp is not using UPSs on their linux game
servers...(they feel if it crashes, they will just reinstall if need be,
whereas the bread and butter servers are on UPSs), I wanted to find another
alternative in light of the danger using async poses...but, I guess
isolating async to one small partition wouldnt be so bad. Ill give it a try.
If you have any further suggestions, I would be happy to hear them.
man I need to get some sleep hehe

Have you tried mounting the drive asychronously? Linux (and possibly
FreeBSD) mounts drives asynchronously, while OpenBSD mounts
synchronously. This slows down disk IO in exchange for increasing
recoverability. See FAQ 11.5
I'd suggest setting aside a partition for the maps, or (if you can't
get just the maps on there) the whole HL/CS data, and mounting that
partition (and only that partition) asychronously.
