Question : Can I revert to a previously published Wordpress page?

I updated some headline text today on a site and after I published it, the form that was there disappeared. I see no backups that are recent. Is there any other way to get that previous page back online? This is not the most current version of Wordpress and it has been modified a lot.

Is it just your C:\ drive that is listed as 70 gigs?  It may just have backed up and restored your partition, and left the rest of the drive unallocated.  Try going into disk management (start -> run -> diskmgmt.msc) and seeing if you have about 250 gig of "Unallocated space" - you can make a new partition there to make use of the rest of your space.
