Hey, I recently upgrade my hard drive in my macbook to a WD 250GB SATA drive. the problem I'm having is that every few seconds of inactivity the hard drive sounds like it 'parks' it's head. The SMART status of the drive is verified. Apparently this is the solution : http://wdc.custhelp.com/cgi-bin/wdc.cfg/php/enduser/std_adp.php?p_faqid=1414&p_created=1138984716&p_sid=Zq6uN4Hi&p_accessibility=0&p_redirect=&p_lva=&p_sp=cF9zcmNoPTEmcF9zb3J0X2J5PSZwX2dyaWRzb3J0PSZwX3Jvd19jbnQ9NSZwX3Byb2RzPTE5NCZwX2NhdHM9MCZwX3B2PTEuMTk0JnBfY3Y9JnBfc2VhcmNoX3R5cGU9YW5zd2Vycy5zZWFyY2hfZm5sJnBfcGFnZT0xJnBfc2VhcmNoX3RleHQ9Y2xpY2tpbmcgbm9pc2U*&p_li=&p_topview=1 But I'm obviosoly on a mac running osx with no floppy drive, so does anyone know how to apply that patch? Thanks.
