ebadblocks is a version of badblocks with extended functionality.

badblocks potentially takes a (very) long time to run. ebadblocks provides support for keeping track of where the last run was stopped in order to easily continue later.

ebadblocks achieves this by saving the last completed block in the ./.ebadblocks file. The run can then be continued from the last completed block by passing the --continue flag.

Example:

sudo ./ebadblocks -vnf /dev/loop0 1000000 100
# Kill the process by pressing Ctrl + C
sudo ./ebadblocks -vnf --continue /dev/loop0 1000000
