Default My camera card is suddenly write protected; can't turn that off

The memory card from my Canon camera, when inserted into the computer,
is now permanently write protected. This means that I can not delete
picture files, as I have been doing for years.

How can I undo this? "Properties" shows no "security" tab at all for
setting permissions.

CompactFlash and SD cards are almost universally formatted to some version of
FAT, so there isn't a security tab because the file system doesn't support
any kind of security beyond "read-only" and "system".

Assuming J. P. Gilliver's suggestion doesn't help, I would assume the card is
failing and replace it. They have a finite lifespan, and generally fail to
read-only mode. Eventually you'll find that both your computer and your
camera are unable to use it at all.

Yes: I forgot to ask, can you still delete from it in the camera, singly
or all images. And/or, can you _format_ it in the computer - or the
camera.

Read my post.
I'll bet if you put it in a Win 7 PC and do the error-check it will
un-write-protect it. You may need an adapter SD to USB if your PC does
not have an SD slot.

I have to do this for a particular brand SanDisk flash drive once in a
while.

Yes, it works normally in the camera. Of course there are over 1000
pictures there, so navigating thru them is quite a chore.

Bingo. I didn't even know that was there. It was in the right position
but pushed just slightly off. Live and learn....

Thanks,

Glad to be of service! (Vmm.) Yes, they can get knocked out of position.

The worse situation is if the card goes write-protected as you are putting
it back in the camera. I've got into the habit of always checking that I can
take a test photo as soon as I replace the card after copying data off it.
Having the switch on the side, where it can slide to the locked position as
the card is being inserted, is a slight design fault.

I wonder how many people actually ever set the card to read-only and would
miss it if the feature was removed...

You may also need a USB-SD adaptor if the slot that is built into your
desktop or laptop PC decides to stop recognising that the card has been
inserted. My Win 7 desktop does this sometimes: it recognises the card until
it is removed and then won't see it again if it re-inserted until the PC is
rebooted. The drive is visible in Windows Explorer but the card is not
detected.

It's a continuation of features on more ancient storage media.

I have SCSI drives with a DIP switch bank on the drive, where
one of the switches is WP. It prevents writes to a SCSI data drive.
There have even been OSes that "tolerate" being read-only. Windows
isn't one of them.

Various floppy formats used to have density holes or
write protect sliders. The 1.44MB floppy in front of me,
has a slide switch for write protect.

The inclusion of such a feature on an SD, is just "copying"
the feature from history. It's of limited value in the real
world, because of the ease of moving the switch to the
other position, and overwriting the device. Of course,
with an SD, it also has a security suite, and that
could interfere with your fun too. I have no idea
what features it's got, where you would enter a password
and so on. But it got the name Secure Digital for some reason...

If ATA hard drives had a WP switch, I'd be in Heaven,
because it would mean I could install Windows on Drive X
and "switch off" Drive Y and Drive Z and know for a
fact that the MBR on Drive Y or Drive Z could not be
overwritten by the OS install. It's little known, that
if you switch off drives in the motherboard BIOS, it
makes no difference at all - an OS can switch them
on again. The beauty of WP switches, is they're electromechanical
and it's harder for shenanigans to happen. That's a feature
I miss, from having stopped buying SCSI drives.

Have you checked with Windows' Disk Management as well?

Interestingly, the camera seemed not to notice. While trying things I
moved the card back and forth several times. File delete worked while
it was in the camera only. That's why I thought it was a Windows
problem.

A fake WP switch isn't much better. The physical switch is just an input
to the computer (it knows you don't want writing, but it CHOOSES whether
or not to honor that). A real WP switch would actually prevent writing.

My camera seems to ignore the WP switch too. That's one way I know it
wasn't a real one.
