So I have one of these little Creative Vado digital cameras. I've been using it for a couple of years now, and I've noticed that recently the recording time seems to be getting less and less. It's flash based memory so I figured it was something to do with the memory being reused and unusable after time. I figured it was time to buy a newer one, something that had a bit more record time.
On a whim I decided to poke around the filesystem using the shell to see where the space was being used. Surprise - the Mac had created a .Trashes folder and was happily squirreling away all the deleted videos. DOH! About 7.6G of space. Double DOH! Frustrating because this trash doesn't show up in the finder when I just browse the device. Would be nice if I had the option in the finder to disable keeping trash on certain devices.
I manually did a rm -rf on .Trashes and my record time went from 9 minutes (!) to 2 hours and 11 minutes. Schweet!
