回複：dim question! What is the difference between second hard

1. What is the difference between second hard drive (local disk D) and local disk C?

答：如果是隻有一個硬盤，如果該硬盤壞了，資料就會全部丟失。如果你有兩個硬盤，另外一個硬盤的資料就不會丟失。

2. Can I install application software in local D?

答：完全可以。

3. How can help the computer after install local D, can it improve the compute speed or just get more storage?

答：簡單的說這樣不會提升電腦的速度，但的確可以增加容量。

4. To reduce the risk of loosing data, does it help if I have copies in both drives?

答：需要保留的資料，完全應該複製到兩個硬盤。
