Hello, I had to switch back for a number of reasons (to the Pc World). I liked the Mac platform but the Word processing just killed me (long story) Anyway, I got myself a Sony because I heard they were comparable to Mac, and I paid a bit of cash too. I noticed the hard drive always makes this clicking noise, almost constantly. Does anyone know the solution to this/or if there is one. I thought with all the former pc users on here, and the general knowledge, that someone may have some info. thanks in advance.
