G'day All

Is there a way to find out how much space you have used or have remaining on your TiVo hard drive?

I have the 160GB version with a 1TB expansion drive.
I have found that the info for each recording indicates its own size and the percentage of the total disc space available but have not found a way to see the total amount of space still available/used.

I hope there is a simple way and this is not an over-site in the TiVo system.

Regards
Andrew
