After last update my system became behave strange. After 15-20 minutes all drives become read only. In terminal I get errors: I/O error, Bus error, disk is read only.

I checked all my disks by smartctl, everything is ok.

$ sudo smartctl -a /dev/sda
SMART Self-test log structure revision number 1
Num  Test_Description    Status                  Remaining  LifeTime(hours)       LBA_of_first_error
# 1  Extended offline    Completed without error       00%      5681         -
# 2  Short offline       Completed without error       00%      5680         -

$ sudo smartctl -a /dev/sdb

I tried to move my system from sdb to sda, but nothing changed.

dd if=/dev/sdb1 of=~/sdb1.img
dd if=~/sdb1.img of=/dev/sda1

Kernel:

$ uname -a
Linux sab 3.8.0-25-generic #37-Ubuntu SMP Thu Jun 6 20:47:30 UTC 2013 i686 i686 i686 GNU/Linux

How can I find my problem and fix it?

    First of all: Don't use dd on SSDs especially not if TRIM is activated.

  • Both disks are affected? I know about certain Crucial M4 disks failing, it could be a coincidence. Have you tried one of the previous kernels?

  • Yes, are both. Rebooted to previous kernel: $ uname -a Linux sab 3.8.0-24-generic

    It is Crucial M4 hardware problem. I have the same errors on another notebook. Thanks, for help.

    I fixed my problem with Crucial M4 SSD by upgrading firemware from 0009 to 070H.
