Re: Protect or lock directories on USB external drive?
not a really good way other than encrypting them.
For one thing, if they hook it up to.. say a windows system, and they sign in as administrator, then they have rights to all files on the drive. Same thing with a linux system. If they sign in as root, then they will have access.
It also depends on what you mean by "lock" directories/folders too. Do you wish to lock it so they have no access? Not even read access? Or just lock it so they can't delete files?
