Aside: It's a hangover from 'the old days' I suspect, Windows allocates a
swap file dynamically (unless you have sense and fix/disable it. ;) ) so
people always liked to have some space left over, unfortunately as the drive
size has grown assumptions seem to have grown too, so people assume you need
gigs free when in reality a few tens of megabytes will be fine. (although
windows panics and moans when your free space gets low, so that doesn't help
either.)

I've run windows machines with about 50MiB free with little or no problems.
As with any operating system you need enough disc space for the swap file to
grow into (if it's windows) + whatever tempory files are likely to be
written.

FWIW, with my previous mythbox I had my 'keep free space setting' at 1G (as
I had recordings on the system drive) and had no problems, from the figures
above Tom is averaging anywhere between 2 and 6 gig an hour, I'd be very
suprised if, even with ext3 and slow deletes, myth couldn't delete files
faster than this.

Amen to that! Too many people seem to buy these things to keep cobwebs and
tumbleweed in. (Now if only I could get 64bit working reliably I could /use/
all my memory. Hmmm.)
