Well, 5 x 500 MB = 2.5 GB, but since you've limited your bin to 1.8 GB or so, they're not all gonna fit, only 3 of them.


If you want to disable the bin for a drive, right click the Recycle Bin, go to the page for the drive you want to change, and tick the Do not move files to the Recycle Bin. I'd recommend making sure the Display Confirmation dialog is checked though if you do that, just in case you hit delete in the keyboard by mistake for one reason or another.

Note that this isn't the same as shredding though. Shredding makes the undelete thing impossible by trashing the contents of where the file used to be, so even if you did try to recover it, you get garbage. That's also why it's so slow, because unlike a normal delete, which only removes the filename from the directory structure and marking those bits of the disk as free, the shedder writes over the entire contents of the file instead (multiple times depending on it's settings), which is going to be much more data changing on the disk.
