Resume "badblocks" command.

[hack3rcon]

Hello,
Is it possible to resume badblocks command?
I did:

Code: Select all

$ sudo badblocks -vw /dev/sdc
Checking for bad blocks in read-write mode
From block 0 to 7562495
Testing with pattern 0xaa:


And canceled that command:

Code: Select all

...
3607
3608
3609
3610
3611
3612
3613
3614
^C

Interrupted at block 3615


Is it possible to resume it?

Thank you.

man badblocks

first-block is an optional parameter specifying the starting block number for the test, which allows the testing to start in the middle of the disk.

It depends of the full command arguments. Sometimes yes, sometimes no.

first-block is an optional parameter specifying the starting block

Specifying a starting block is not the same as resuming at this block. In the example given here, badblocks is supposed to do 4 write+read passes using different test patterns but was interrupted during the first write pass. Resuming would mean skip completed passes, skip blocks 0-3613 for the interrupted pass only and do all subsequent read and write passes starting at block 0. Specifying 3614 as the starting position means start over and skip blocks 0-3613 at all write+read passes.
