My brand new uMBP 5,4 got a new seagate momentus 500gb 7,200 rpm HDD put in, and I think it just beeped. It sure sounded like it. Is this bad, or even possible?
I'm not sure if Apple hardware (like PCs) have that little beeping hardware thing, and I'm pretty sure that Apple would not make their pristine OS make such a primitive sound. You probably heard the hard drive head engaging, and if the drive is new, then the metallic clink will be more pronounced.
And it was a pretty distinct computer beep, coming from the corner of the laptop where the hard drive is. It sounded like the beep a PC motherboard would make when it was angry.
