I have an external HD ("850 GB EXT") that was, at one time, the boot volume for an older iMac. I put it in a case and converted it to an external backup for my present system (mid-2007 iMac running El Capitan). Being a bit lazy, I left all the old files in place, in case I might want them for anything.
That was a few years ago, and by now I've rooted around and copied out everything worth saving. Time to clean up and make room, so I started deleting the folders (Users, Applications, etc.) By one means or another, including forced deletions (sudo rm), I've gotten it down to a single System folder and four nested folders within: System>Library>Caches>com.apple.kext.caches>Startup. The folders are empty, and add up to zero bytes.
This is where it gets weird. I can trash any of the internal folders, and empty the trash, but when I try to delete the System folder, it re-appears in the HD directory within a few seconds . . . with the four nested files resurrected as well. There's an image in the Trash, which can be emptied as if nothing was wrong. Console has some interesting output - the following appears consistently when I drag the System folder to the trash:

It's odd that the Finder can locate these, while deeper system processes can't. They take up zero bytes, but I think it's bogging down some processes - the Mac is noticeably quicker when the drive is not mounted.
Re-formatting would be a pain - I'd have to relocate about 450 GB of images and video to DVDs, or buy yet another external drive. Anybody have any ideas about how to kill a zombie folder?
