Perfmon reports incorrect free megabytes

I've set up alerting on my file server to let me know if any of the
volumes have fallen below 5000 free megabytes. Tested it by using
creatfil.exe to nearly fill a drive, and all of the alerts worked.
However, one volume, the g: drive, has reported insanely low free MB.
It's got 17.5 GB free, but I recd a couple of alerts reporting that
its down to 243MB or 4.3 GB free.

I've looked around, but can't find anything to debug the alerting
mechanism.

Thanks!

Jeff

Perhaps it's checking a volume with quotas enabled.

Nope. No quotas.
