Re: best practices for an external hard drive that many hosts might use?



 I'll second what the other Brendan says and say this discussion was very 
helpful. Thanks to all who made suggestions. 

It appears that it is simply impossible, in Linux, to do what I want to do 
using a Linux-native filesystem as native filesystems are always mounted 
with normal Unix permissions enabled. After much hemming and hawing on 
Thursday and Friday, I decided to use the Linux command mkfs.ntfs to format 
it as an NTFS volume. (FAT32 is unacceptable because of a hard limit of 4GB 
per file, and with a 300GB disk I am likely to drop large backup archives 
onto it.) 

It feels weird to be using a reverse-engineered proprietary filesystem 
because the drivers for the native filesystem don't satisfy a rather simple 
requirement of disabling permissions and having the whole mounted filesystem 
owned by the user that mounted it. In the end, NTFS gets the job done, and 
of course it's compatible with Windows and OS X. 

(META: If I understand correctly, I accidentally just sent this reply to 
only Brendan. Sorry about that. The list's messages don't seem to have a 
proper reply-to header.)
