Badblocks not displaying "Pass completed" after finishing

Question

This is the command I am running to test a HDD with badblocks:

badblocks -b 4096 -c 98304 -w -s /dev/sda1

The output is:

[root@localhost liveuser]# badblocks -b 4096 -c 98304 -w -s /dev/sda1
Testing with pattern 0x55: done
Reading and comparing: done 
Testing with pattern 0xff: done
Reading and comparing: done 
Testing with pattern 0x00: done
Reading and comparing: done 
[root@localhost liveuser]#

Is this correct? Does this mean the drive passed? I thought there would be an output such as "pass completed" or similar. For example this is question has a different output to mine https://unix.stackexchange.com/questions/65349/how-to-interpret-badblocks-output

Your drive is fine. If you had failures it would have ended with a list of the failed blocks. — Zoredache, Jul 24 '13 at 16:40

Add the -v switch (verbose) to get a summary:

# badblocks -v -b 4096 -c 1024 -w -s /dev/sdb
