Subject: [gentoo-user] [OT] Badblocks on my harddisk
Date: Sat, 26 Jul 2014 03:49:15 +0200	[thread overview]
Message-ID: <20140726014915.GA3845@solfire> (raw)

Hi,

After running smartctl for an extended offline test I got
a badblock (information extracted from the report):

SMART Self-test log structure revision number 1
Num  Test_Description    Status                  Remaining  LifeTime(hours)  LBA_of_first_error
# 1  Extended offline    Completed: read failure       90%     14460         4288352511
197 Current_Pending_Sector  0x0032   200   200   000    Old_age   Always       -       1

I found a explanation to map the LBA to a partition here:
http://smartmontools.sourceforge.net/badblockhowto.html

My partition layout is:
#> sudo fdisk -lu /dev/sda

Disk /dev/sda: 931.5 GiB, 1000204886016 bytes, 1953525168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x07ec16a2

Device     Boot      Start        End    Blocks  Id System
/dev/sda1  *          2048     104447     51200  83 Linux
/dev/sda2           104448   12687359   6291456  82 Linux swap / Solaris

/dev/sda12      1491195904 1953525167 231164632  83 Linux
                4288352511  <<< The number reported by smartctl


Following the linked document...
It seems the bad LBA is not on the checked harddisk.

Or (more obvious) I did something wrong...

How can I correctly identify the partition, which contains the bad
block?
How can I get a full list of all bad blocks (if any) from a mounted
file systems?
How severe is the problem?

Thank you very much for any help in advance!
Best regards,
mcc
