    I read that link and it looks like it's definitely specific to this. Nov 13, 2014 at 0:48
  • Ivan, the link mentioned explains that badblocks can't cope with HDDs that large. You'll not get it to run on your 6TB HDD, no matter what you'll do.

for me the trick was to simply increase the blocksize:

badblocks -b 4096 -v /dev/sda

  • Thank you. This worked for my 10TB drive. Hopefully for my 16TB drive soon
