Ok, this is... I feel like I really should know this by now, but... When I do a mkfs -c -v on a new filesystem, I get this while it's running: Running command: badblocks -b 4096 -X -s /dev/sdg1 732566384 Checking for bad blocks (read-only test): 51.39% done, 3:23:10 elapsed. (0/0/0 errors) Note the 0/0/0 errors part. Also note that it takes about 3.5 hours to do 50%. Therefore if I have, say, several of these drives, I run a batch and don't sit here watching. Which means that when the mkfs process is done... it doesn't tell me anything about how many errors there were. At the end, I get this: Running command: badblocks -b 4096 -X -s /dev/sdg1 732566384 Checking for bad blocks (read-only test): done Now, does this mean there were NO bad blocks and no errors? Or does it hide them somewhere? Is there a command that'll tell it to just display bad blocks (if any) or tell me if there are NO bad blocks? TIA! --
