hard drive - noise and clicking
I mounted a 7200 RPM hard drive in my macbook pro and I often hear a click followed by the OS freezing for a while.
I've tried every fix I've found, like disabling the motion sensor, to keep maximum power on to the hard drive.
The new macbook pro has the same problem, but I'm not allowed to install the fix in the old one.
The hd is ok, the s.m.a.r.t. report is ok, apple mount 7200 on the new mac book pro unibody and a lot of them make this click noise before the patch(efi?), that unfortunately is just for the unibody.
I make a daily backup for the work and a weekly for everything else.
