Checking ext3 partitions for disk errors

We can use following command to check ext3 partitions for disk errors / surface scan for bad blocks:

e2fsck -c -c -k -v -C 0 <partition_device_name>

Here:

• -c : To call badblocks for surface scan
• -c : Repeated to indicate non-destructive read-write tests
• -k : Preserve previous list of bad blocks
• -v : Verbose
• -C 0 : To print progress on file descriptor. For some strange reason 0 causes output to be sent on screen.

Note:

• It is advisable to use e2fsck in above format so that it calls 'badblocks' internally, and we should avoid calling program badblocks directly.
