楼主，用软件前麻烦先好好读读软件的说明。dh的说明里明明白白写着的：
Q: What is "Spin up time"? My disk reports "Spin up time" about 75, is it about to crash?
A: "Spin up time" describes amount of time it took to spin the platters up to their rated rotation speed (usually 5400 or 7200 RPM). Values above 80 should be considered good. Values between 70 and 80 are still acceptable. There is a known issue with Quantum (Maxtor) hard drives - out-of-the-box new drives drop "Spin up time" to 70 within first two weeks of use, causing program to predict failure within a month. This is usually a false alarm. After some initial "burn-in" period "Spin up time" becomes constant and the drive functions normally.
而且这是一个普遍的现象，对于新硬盘都有一个磨合期。等磨合期过了就好了
