my little indigo imac suffers from the pesky "beeping sleep" problem due to its maxtor drive which even causes delays in the drive turning on at boot time. i'm looking into replacing the drive and was wondering if anyone has any horror/success stories about 7200rpm hds in the crt imacs. i realize that this is not advised due to heating factors and will void my warranty blah blah blah... but i've heard reports that some western digital 7200 drives run at the same temp as my maxtor 5400. i can use any little speed bump and just wanted suggestions on whether or not people had problems and if so, with what brands.
