Yes. In fact, I had one SD card where the sliding switch fell out--
and I subsequently lost it, making the card `permanently write-protected'.

But I replaced the missing slider with a bit of tape, just like we
used to do with VHS cassettes..., and guess what? It was writable again
(though, mind you: it was somewhat harder to layer the tape into that
space on the SD card that it ever was to tape over the write-protect
hole on VHS cassettes...).

Another adapter will probably help. I do have short related story that
might be insightful.

I have found that the locked position is normally pushed furthest away from
the reader. Giving this was the case with one of my micro sd adapters,
whenever I would push the card into my laptop the reader would catch the
side of the latch and lock it. (how helpful! ) A very narrow strip
of duct tape holding the latch fixed this issue.

Pretty sure that write protection is determined by the reader by "feeling"
for the tab. I don't think it makes any sort of electrical connection.
Scotch taping the whole thing over without covering the connectors may
solve this issue if the issue is in fact physical. Which from the sounds of
it, probably not. Doesn't hurt to check for the cost though. Note that the
notch on the other side of the card is also used to determine write
protection in some cases.

Cheers,
Paul

​Check the 'dmesg -T',  'mount', 'hdparm', 'fdisk -l', and
'/var/log/messages'  output for clues. ​

Some distros default fat, vfat, ntfs file-systems to read-only for safety,
don't know if that's your case. Devices also remount r/o on error.  If
'mount' reports 'ro', but no errors listed, a 'mount --options remount,rw'
should work.

Sometimes a specific reader doesn't like a specific card, so try another
one. E.g., my USB hub has slots for everything, but the uSD slot isn't
reliable.

what distro are you on? i've had similar issues on my macbook pro running
ubuntu. i was using a microsd card via an adapter. i used a usb adapter

​Since mount reported 'rw', 'mount ...remount,rw' isn't needed, wasn't the
