       | Yes, I can mount 'ro', but many (all?) Linux Desktops mount the
       | drive write through its GUI. I have aliases for mounting and
       | never used the pointy-clicky mount in DEs.
       | 
       | FWIW, I am usually in fvwm or cwm, depending on screen size, so I
       | mount 'ro' when I want to. But a hw switch on flash drives would
       | have been nice :)

           | I thing I learned only recently is that the write protect

           | to anything in the SD card itself: it just hits a lever in
           | the SD socket that opens a contact closure and it's up to the
           | system (hardware and software both) to bother to look at it.
           | So on many systems the write protect switch doesn't even
           | work.

         | With the default ext4 filesystem, mounting 'ro' doesn't
         | actually prevent writes to the disk. For that you need 'noload'
         | too, to prevent journal replay. This can result in a broken
         | filesystem if it wasn't unmounted cleanly, although assuming
         | it's 100% read-only it shouldn't do any permanent damage
         | (perhaps enforce read-only access at the block device level to
         | be sure).

       | As a kid (ok, as an adult too), I knew what the "CH" on floppies

       | 
       | I forget when, but one day, it dawned on me that it said "HD"!
       | 
       | I guess most of my floppies had their labels on in such a way
       | that the flap/door was facing down, so it said "CH". To read
       | "HD," then the label would be upside down.

       | A trivia not touched on in the article - IBM 5 1/4" floppy drives

       | without flipping. For cost savings Apple ][ drives had only one
       | head so you had to flip the disk occasionally. But to convert an
       | IBM 5 1/4" floppy for dual sided used on an Apple, you had to cut
       | a second write-protection notch, either with scissors, and xacto-
       | knife, a hole punch, or with a dedicated "drive doubler" puncher.
