I have an Olympus DM-520/550 voice recorder that has a SD slot for extra memory.
Under linux the extra card is not recognized. Only the internal flash.
So after some digging I found that setting "options scsi_mod max_scsi_luns=2" might be an answer.
Not only the second card wasn't recognized but now even the internal flash gives IO errors even after removing the option.
Any suggestions much appreciated.
Thanks and all the best.
