USB drives could use such a feature.
write-lock: prevent it from beint written (and acquiring viruses)
read-lock: prevent it from being read (and passing viruses), only showing the free space and being able to write only in the free space
- estel 16y agoI have several USB drives with at least the former feature.
- limmeau 16y agoI have a USB stick with a write-protect switch. Unfortunately, the switch has broken. Now the drive will contain 128MB of obsolete early-00s data until the bits diffuse away.
- jarek 16y agoSD cards have a write-lock. It always amazes me that it's purely physical and only a suggestion to the software.
- technomancy 16y agoGotta love how the write-lock switch is positioned just perfectly so that inserting it knocks the switch into read-only position.
- jarek 16y agoDoing that rather than switching into write-allowed position is a good example of fail-safe design. But yeah, I've had that happen more than once.
- nitrogen 16y agoOn some SD cards in some SD readers, the write-lock switch is too small to trigger the mechanical switch in the reader, making the card appear as read-only until tape is applied over the switch. This problem affects my BeagleBoard's OS SD card.
- th 16y agoI only ever had drives with write locks. I must have gotten into USB drives late because I've never heard of read lock.
