Buffer I O Error On Device Sr0
HDD I sometimes getting messages in my logs which saying: Buffer I/O error on device sdX, logical block XX Where the X stands for the device for example: sdc. How I seriously do I have to take these messages since the device only spewing this messages when I unmount it, when I mount and use it I don't get any messages and the device works fine at this point as far I can see. mount external-hdd share|improve this question asked buffer io error on device sda Nov 18 '14 at 1:39 Allard 1616 Hard to know without more information. I suggest you run fsck on the partition(s) and use smartmontools smartctl -a /dev/sda or smartctl -H /dev/sda change sda to your hard drive –bodhi.zazen Nov 18 '14 at 2:10 I have 2 external HDD's. One was able to give me info about the smart. dropbox.com/s/81nndc10yqy5ux8/smart%20first%20hdd.txt?dl=0 –Allard Nov 18 '14 at 12:58 The one that is giving the messages ? Is it healthy ? –bodhi.zazen Nov 18 '14 at 13:00 Those results look alright, see thomas-krenn.com/en/wiki/SMART_tests_with_smartctl –bodhi.zazen Nov 18 '14 at 13:08 The second drive I had to use in Windows and check with CrystalDiskInfo for the smart status. Note that this is a Seagate Disk. dropbox.com/s/v6bj2x4l1epao9z/smart%20hdd%202.png?dl=0 –Allard Nov 18 '14 at 13:10 | show 2 more comments 3 Answers 3 active oldest votes up vote 0 down vote Typically, this buffer issues can be indicative of a pending HDD failure. However, it is best to test the drive and verify and see where exactly the error lay. Please run e2fsck -fv /dev/sdX. If it runs without error, then there must be something else wrong. If it has any errors or mentions moving sectors, backup immediately and prepare to replace the drive. I recommend replacing it sooner rather than later in that case share|improve this answer answered Nov 18 '14 at 2:09 Geary Shull 232

I wonder if anybody knows how serious are these issues. I cannot use smartmontools because the disks are handled by a 3ware card which error on device has it's own (very limited tw_cli utility).
