My 701C 720 MG HD is about two months old. It has a total of 24M ram and ins running Win95. About 3 weeks ago the HD died. IBM replaced it with a new 720 HD. It was noisy to the extent that I sent it back. The 2nd replacement is also is also noisy. Is this standard? The original HD was quiet. What is everyone's experience? Are they most all noisy? Hope not. PATRICK
