#StackBounty: #terminal #badblocks badblocks: Resource busy while trying to determine device size

Bounty: 50

I am trying to run bad blocks on macOS High Sierra 10.13.6. I installed bad blocks using macports. I keep encountering errors when attempting to run it and I am not sure how to even get bad blocks running

sudo badblocks -c 4096 -s -w -o /Users/mcbeav/Desktop/blocks.txt /dev/disk0s2

This keeps returning the error

badblocks: Resource busy while trying to determine device size

If I try

sudo badblocks -c 4096 -s -w -o /Users/mcbeav/Desktop/blocks.txt /dev/disk0

I get the error

badblocks: Value too large to be stored in data type invalid end block (7813820416): must be 32-bit value
