Ok that makes sense. What about software raid? Would software raid still be one you wouldn't "shred" a file on? Or would it operate just the same as a regular independent drive for secure erasing?
And while it's true that recovery programs would be stymied by just writing zeros, a physical hardware recovery is still possible in certain lab situations. Since I'm rather extreme about my privacy at times, I want to be able to ensure that any file I "shred" is unrecoverable, period. Yes, I understand about hot spares. But that's not a big deal. In the event of a raid substituting a hot spare for a regular member drive, I can just use the secure erase program on the file, and then use the libata secure erase on the drive it kicked out (provided the drive is still recognized and was just kicked out for an error. If the drive is totally dead then it's a moot point anyway because nothing short of a good strong magnet will change any data on the platters). Thanks for all the info guys! --- Dan /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
