Please show the outcome of

  ls -l /dev/sdc
  getfacl /dev/sdc

My french suffices to decode the statement and to assume that this
was originally EROFS "Read-only filesystem" before it fell victim
to i18n.

But if i have no write permission when attempting to write by dd, i get
  dd: failed to open ‘/dev/sdc’: Permission denied
which is EPERM, not EROFS.
So aside from the i18n ambiguity, i cannot really reproduce the situation.
But i only have USB sticks, no memory cards.

Can it be that a read-only switch is activated at the card or the
device where you put it in ?

Have a nice day :)
