Laptop HDD issue

[Thanir]

I have a Inspiron 6000 witha 60gb hdd. A few days ago the comp really slowed down anytime it had to access the hdd. First I thought I didn't have much space left on it, but I had 10gb free on it, so I ran a speed test on it using HD Tach. Results:

Random Access: 21.8ms
Avg Read: 1.1MB/sec

So it seems my HD is dying? I then ran Active Smart 2.6, and the SMART report says everything is good. So is it actually my harddrive that is the issue, or could it be my motherboard?

I am going to buy a new hdd for the lappy, but I don't want to waste my money if the actual hdd isnt the issue.

Any thoughts?
