216 Discrepancy between gdmap and freememapplet

[PaulBx1]

I have a 512MB pupsave and boot off floppy with the pupsave on the hard drive.

Freememapplet says I have 199MB left.

When I open /initrd/pup_rw (which I believe my pupsave via /dev/loop1) in gdmap, the figure at the upper right above the graphical display says "274.2 MiB". I assume that is saying there are files amounting to 274MB in my pupsave.

Well, if you add 274MB used, to 199MB left, you get 473MB total, 39MB short of the pupsave size of 512MB. What happened to those 39MB? Is there more stuff in my pupsave than what is in /initrd/pup_rw?

I tried to find docs on gdmap, to be sure that figure above the display means what I think it does, but there are no docs on sourceforge. Or at least I didn't find them.

I've never been able to make sense of gdmap or freememapplet. Some of the discrepancy you report could be due to video memory, but not that much. What does "free" report? (When you run it from a console.)

Not sure what that has to do with it. I am talking about the pupsave...

Well, I guess this is not that important. If I get really irritated I might dig into gdmap and freememapplet and see how they are determining these numbers.

#df -m will probably confuse matters more??

It says 278MB used. Note, df says I have a total of only 496MB, not 512MB. Maybe the rest is filesystem overhead?

At this point gdmap says I have 274.2MB used.

Partview says I have 278MB used and 192MB free (for a total of 470MB!)

Freememapplet agrees I have only 192MB free.

I just don't like this feeling I am not getting my advertised 512MB. 40MB of overhead sounds like an awful lot.

I wonder if some of these are reading in 1024*1024 bytes, and others in 1000*1000 bytes. The latter should be banished from the world of computers!
