    I read that link and it looks like it's definitely specific to this.

  • 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.

Reset to default

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

    @PocketSam that's because 4096 x (2^32) = 17592186044416, or 16 TiB. Your 18 TB disk (18,000,000,000,000 bytes) is 16.37 TiB, so 0.37 TiB too large for 4096 byte blocks at 32-bit. You'll need a larger block size, e.g. 8192 bytes, though I'm not sure what exact size is ideal to use beyond 4096.
