20:03 * mr_lou has spent the past two days experimenting making a USB write-protected / read-only.
20:04 mr_lou :-S
20:14 pdurbin This was a solved problem with floppy disks.
20:15 mr_lou And also early USB flash drives. They came with a hardware switch.
20:15 mr_lou But those aren't really around anymore. If you stumble across one, it's almost always USB2.0 and small in size.
20:17 pdurbin When I was a kid I was somewhat paranoid that I would accidentally hit the record button and record over my favorite cassette tapes. Little did I know that they probably already had the tabs removed to prevent recording.
20:17 mr_lou hehe
20:18 mr_lou There are also Write Once Read Many (WORM) USB drives around. But they are rare and expensive. And I don't know how it works regarding getting data onto them.
20:19 pdurbin Is the write protected stuff in the USB spec but no one uses it? Maybe you could bring it back. :)
20:20 mr_lou There are 3 kinds of write-protection, as far as I can tell.
20:20 mr_lou The first one is that hardware switch.
20:20 mr_lou 2nd one is by using a harddisk tool on Windows: diskpart.
20:21 mr_lou 3rd one is by editing registry database in Windows.
20:21 mr_lou 3rd option obviously only works on the PC you do this with.
20:21 pdurbin what if you're on Linux?
20:22 mr_lou Yea, then whatever you did with diskpart on Windows doesn't mean shit.
20:22 mr_lou But... you can mix things then.
20:22 mr_lou Create UDF filesystem on the drive with Linux. Set mode = 0555
20:22 mr_lou Then it's write-protected on Linux.
20:23 mr_lou Then go to Windows and run diskpart. Then it's write-protected on both OS's.
20:23 mr_lou I need to test on Mac.
20:24 mr_lou It would be nice to have some way of controlling the firmware in the USB though.
20:24 pdurbin It sounds like that hardware switch should make a comeback.
20:33 mr_lou I would like to see that too yes.
