How do you use badblocks?

I need to do a destructive (rw) test on a new drive, and a read-only on a drive that fell out of my RAID array. I want to see if it finds problems and how far along it is.

Method 1

Let /dev/sda be the new drive on which to test destructive-rw and /dev/sdb the old drive where you want non-destructive-r

# badblocks -wsv /dev/sda
# badblocks -sv /dev/sdb

-s gives the process indicator

-v gives verbose output

-w enables destructive read-write

-n would be non-destructive read-write

Read-only testing is the default and doesn’t need special parameters.
