Unlocking an SD card
 

We've got an 8gB SD card that has lost its "write-protect" switch which has
unfortunately converted it to read-only.

A quick shufti inside doesn't reveal any obvious switch connections so I'm
guessing the switch jumpers a couple of legs on the memory chip.

If there anyway of rescuing the card? It's not really about the money, just
the challenge. ;-)

There are no switch contacts in there, the switch is in the socket.

Just use a bit of thin tape/epoxy/bodyfiller.

Doh! Should have realised.

Not all sockets even bother connecting up the switch contacts.
In any case, it's up to the OS if it takes any notice of write
protect on SD cards - it's not implemented in hardware.
