Be careful with the -S values over 240. If you read the man page, values over 
240 are interpreted differently than lower values and unfortunately there is no 
complete list of which drives interpret it how... I had a really old drive 
where 255 reset the firmware. I tried over values and when I hit 250, the drive 
locked up ...
