Comment 34 for bug 952556

Just to add my 2 cents worth, I'm concerned that there are a class of "green" drives out there on the market where hdparm -B 255 is the only way to ensure they don't excessively impact the Load_Cycle_Count, for example:

WD20EADS, WD20EARS, WD15EADS, WD15EARS, WD10EADS, WD10EARS, WD8000AARS, WD7500AADS, WD7500AARS, WD6400AADS, WD6400AARS, WD5000AADS, WD5000AARS
