What's the point of the SD card write-lock?

Okay, so obviously the point is to prevent you from accidentally writing data (like formatting the card or something). But...does anyone use this as part of their workflow somehow? I just noticed it, and now it sticks out like a sore thumb on all of my cards.

I have not used it for some time since cards are fairly large now, but back when I carried multiple small cards I used the write lock to indicate that a card was full so I didn't accidentally re-use it before I could upload it's contents to my computer.

When I do anything super important, like travel, or anything at a wedding etc, I use this when I swap out cards.
As above though, less of an issue now with the larger capacity cards. But even then I sometimes swap cards to ensure any corruption doesn't take out the whole cards contents.

I mostly swear at it repeatedly. Something in my K3 catches it about 1/3 of the time I put a card in there (or maybe when I take it out, I've not paid that much attention) and then I can't take pictures

I personally dislike the tab because it always gets engaged on accident.

I used it to lock full cards, too. But as the K-1 is delivered without a usb-cable i now lock the cards before inserting them in the card reader... i don't trust windows and think i might lessen the tiny probability of a failure on the next trip.

I've had several break off. I had to use epoxy on a toothpick to "rebuild" the tab.
An ancient hold-over from floppy disks, if anyone remembers what those were.

Not useful if you can't punch a hole in the other side and double your capacity. ;-)

I use it when travelling. It's a quick way to check if the card has images on it. I usually change cards daily. If the card is corrupted, I only lose one days images.

I've also returned to smaller capacity cards for the same reason - I can lose fewer images. I have had cards get corrupted.

It can be useful, but is not fail-safe. Write-lock compliance by readers is optional and may not be complete depending on host operating system.
