1. Right now the permissions for my primary drive are - system - read & write admin - read & write everyone - read only The Permissions on my external drive are - Me - Read & Write Everyone - No Access What are the downsides of no access for 'everyone'? It hasn't bitten me yet but I realise it may one day. Would it be OK to set the primary drive's everyone entry to 'no access' too? 2. How do I give Spotlight back it's permissions after I've remove them from a drive? They were listed previously as "custom" so I have no idea what to set them as. I've tried adding and removing the drive in the privacy list but it didn't work.
