differing drive sizes

[atrain]

Hi, I just used super duper for the first time and have a question before I commit to buying it. I notice that after I did a "back up all files" my destination drive isn't exactly the same as my source, containing an empty folder called "dev" in the main drive directory that doesn't appear on the source drive and overall is about 2.5 gigs smaller in size.

Is this normal and having to do with SD essentially defragging the drive? I want to make sure that 2.5 gigs of data isn't missing and a bit curious as to why some folders are on the destination that don't seem to be on the source.

The /dev folder is relatively normal and expected, 'atrain' -- don't delete it! (It's an important system file that isn't returning that it's 'hidden' when we ask, but should be hidden when you start up from the drive.)

Also, smaller isn't a problem: there are temporary files and swap files that don't get copied (and have no real meaning across a restart).

Hope that helps.
