When I got a new laptop I investigated this problem a little and found that with hdparm -B 254/255 the temperature went up quite significantly. This may be a freak and I would love to know whether there really is something behind it, but when I used -B 200 the temperature increase was clearly smaller, but the load cycle count did not increase!!! Is this actually at all possible? Does the -B option do something other than only affecting head loading? Does anybody know? In looking through the storage-fixup package data I see that always -B 254 or -B 255 is set, so obviously there is no sign of other, possibly more optimal values there.
