Every so often, after restarting my computer, my external drives are re-designated or re-numbered or something, I don't know the technical term for it. The name of the drive under the icon on my desktop stays the same but in disk utility, for example, the drive mount point changes and instead of "/Volumes/DataBank" it is "/Volumes/DataBank 2". This also happens to a drive on my file server I have connected over afp. This is pretty annoying for a couple of reasons but mainly because applications that have saved default locations on either of these drives get lost after this strange numbering thing happens.
