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 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.

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.

Buffer I/o Error On Device Logical Block 0
linux as much as I used to (not after windows 7). I have archlinux buffer io error on device dm-0 running on my HTPC. Never had any issues before that was this severe, unless I upgraded and forgot to read news ubuntu blk_update_request: i/o error, dev fd0, sector 0 section. Booted the htpc today to be greeted by "Buffer I/O error on device sdd1, logical block" with a massive wall of text, a few seconds later "welcome to emergency mode."*This is NOT hdd http://askubuntu.com/questions/550840/buffer-i-o-errors where the linux kernel is residing on. What logical purpose would it serve for the kernel/userspace to abort everything just because fsck fails or something? If this was indeed my linux partition I would fully understand.Anyways, I used parted magic, ran fsck, smart. Sure enough fsck warned me about bad/missing superblock. Restored the superblock by using e2fsck. I had over 10 000 "incorrect size" chunks. Ran 2-3 SMART after that. https://bbs.archlinux.org/viewtopic.php?id=171667 fsck says okay, smart gives a 100% status report with no errors.Oh yeah, I have turned off FSCK completly in my fstab, thinking about at least turning it on my bigger hdds Questions:*Is SMART reliable? If it says it's alright, does that mean i'm safe? Would physical broken sectors turn up by SMART?*I know SMART warns the user in windows 7 if hdd failure is imment. Is this possible within linux as well? Since i'm NOT using a GUI, is this possible to send through a terminal/email?*Sometimes the HTPC have been forefully shut down (power breakage), could this be one of the causes of the I/O error?As always, thank you for your support.

[SOLVED] Any reallocated sectors in smartmontools? If you run 'e2fsck -fv /dev/sdd1' does it complete wo/ errors? Probably best to repeat for all linux partitions on that disk.
