1 Hi,
2
3 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
21 Disklabel type: dos

37 4288352511 <<< The number reported by smartctl

40 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,
53 mcc
