Raspberry Piで使っていたUSBメモリがwrite-protectedに

Raspberry Piで使っていたUSBメモリがwrite-protectedに

ある日

sudo mount /dev/sda1 /mnt/USBMem/

mount: /dev/sda1 is write-protected, mounting read-only

になってしまった

これはUSBメモリが逝ってしまったか?
USBメモリは代替品を用意するとしても、なんとか中身を少しでも取り出したい

とりあえずfsckしてみた

sudo fsck -y /dev/sda1

fsck from util-linux 2.25.2
e2fsck 1.42.12 (29-Aug-2014)
fsck.ext4: Read-only file system while trying to open /dev/sda1
Disk write-protected; use the -n option to do a read-only
check of the device.

と連れない返事

write-protectedならReadOnlyでいいんじゃ

sudo mount -r /dev/sda1 /mnt/USBMem/

には

mount: wrong fs type, bad option, bad superblock on /dev/sda1,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

との返し

ディスクイメージを吸い出してマウントしてみたらどうだろう?

sudo dd if=/dev/sda1 bs=64k of=./sda1.img
sudo mount -o loop ./sda1.img /mnt/img

ををっ うまくいった
