Tom,
you can mount the storage as read-only - any unix filesystem will support read-only mount, and provided your root account isnt compromised, no one can remount it as write. Root cant write to read-only mounted filesystems without remount either.


mount -r /dev/da2 /readonly in BSD land..

Id say thats the easiest route without buying specialized hardware.

Sorry if this is something you already tried/thought about..

Hey all,
I wanted to find out if there was a method to convert an external hard drive enclosure into a "cheap" write blocker device? I'm not looking for something to use from a forensic standpoint. Basically if I want to put a hard drive into an enclosure and pull data/burn data to DVD/whatever off of it, but prevent anything from being written to the drive, I can do that.


Thanks ahead of time,
Tom
