A Life Lesson Learned the Cindy Sue Way was.... one spot to always check is... under /media/[user]... I'd been meaning to write it up. Seems like I had at least one other thought about it, too, but that escapes me just now. So what had happened was... In my instance(s), it was a combination of rysnc and a faulty USB connection for an external hard drive. Rsync would just create a new target instead of complaining that one I wanted didn't exist (because the USB connection had just once again failed).. Since I was copying to that external hard drive, /media/elf/data-partition/copied-files-directory was where it was going. When rsync couldn't find that (because the USB connection had just once again failed), rsync simply created that... SOMEHOW on my primary hard drive under /media/elf. Took a couple months before I discovered it had been happening. That occurred when I by accident noticed something called /media/elf/data-partition_....... And /media/elf/data-partition__ AND /media/elf/data-partition___ Flailing around on my hard drive, all ONLY visible and accessible directly under /media. The additional "__" and "___"? Created k/t a mix of how both rsync and my Debian (likely Jessie as testing then) were trying to accommodate my scenario. The secondary issue became that my Debian very quietly began mounting the (faulty USB) external hard drive by adding its own "_"(s) once the original /media/elf/data-partition name became permanently "mounted" under /media. Apparently addending an upward number of "_" is, or at least was, part of renaming nomenclature done on the fly if something already appears under /media. Moral of the Story is that hard drive space was very quietly being eaten alive while that was going on in a place we don't normally visually inspect... and that space usage also was not being reflected numerically via any utility tool package I knew to run at that moment. See why I hadn't tried to write it up yet? *grin!* Cindy -- Cindy-Sue Causey Talking Rock, Pickens County, Georgia, USA * runs with duct tape *
