Hi, |

After running smartctl for an extended offline test I got |
4 |
a badblock (information extracted from the report): |
5 |
|
6 |
SMART Self-test log structure revision number 1 |
7 |
Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error |
8 |
# 1 Extended offline Completed: read failure 90% 14460 4288352511 |
9 |
197 Current_Pending_Sector 0x0032 200 200 000 Old_age Always - 1 |
10 |
|
11 |
I found a explanation to map the LBA to a partition here: |
12 |
http://smartmontools.sourceforge.net/badblockhowto.html |
13 |
|
14 |
My partition layout is: |
15 |
#> sudo fdisk -lu /dev/sda |
16 |
|
17 |
Disk /dev/sda: 931.5 GiB, 1000204886016 bytes, 1953525168 sectors |
18 |
Units: sectors of 1 * 512 = 512 bytes |
19 |
Sector size (logical/physical): 512 bytes / 512 bytes |
20 |
I/O size (minimum/optimal): 512 bytes / 512 bytes |

Following the linked document... |
41 |
It seems the bad LBA is not on the checked harddisk. |
42 |
|
43 |
Or (more obvious) I did something wrong... |
44 |
|
45 |
How can I correctly identify the partition, which contains the bad |
46 |
block? |
47 |
How can I get a full list of all bad blocks (if any) from a mounted |
48 |
file systems? |
49 |
How severe is the problem? |
50 |
|
51 |
Thank you very much for any help in advance! |
52 |
Best regards, |
