Disable spotlight for External Drives
I have 5 macs, and several USB and Firewire drives. Most of these external drives are plugged into different machines from time to time. None sit permanantly in any machine (because most of my machines are laptops).
I'd like to prevent Spotlight from indexing my External drives.
I know I can (after plugging in a EXT drive), use the privacy function in the Spotlight Preferences. But with a dozen or so external drives (HDD and Thumb) on 5 machines, that's too much work each time I plug a drive into a machine.
I read that the existence of a ".metadata_never_index" file prevents Spotlight indexing. I assume this works, but it's hard to tell for sure, because the moment I plug a drive in, my machine seems to start indexing faster than I can create this file. So I wind up with a .Spotlight-V100 directory. I was hoping that OSX would delete this for me after I set Privacy or add the ".metadata_never_index" file. But it does not. It may be that I have to delete it manually (probably because Privacy is a COMPUTER setting (not on HDD setting).
QUESTIONS:
- Does the ".metadata_never_index" file supported by OSX (Mavericks and MtnLion).
- Can I delete the .Spotlight-V100 directory in my EXT Drives, without the risk of causing a problem?
- If I put a ".metadata_never_index" file in /Volume, will it effectively prevent indexing on any mounted drive, without affecting the Macintosh HD indexing?
- Is there an non-invisible equivilent to ".metadata_never_index" (so it's more obvious when indexing is turned off).
