I've seen a drop in my disk health on Hark Disk Sentinel over the past couple of days. Any explanation?

Selective self-test flags (0x0):
After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.
Data looks ok. have you checked on the fragemntations level? Also purge any pagefile, restore points and hybernate files by turning them off before you defrag. That will give you a clan compacted HD.
Then after defrag turn on the pagefile and restore points again.
And if you are running wubi ubuntu it makes a big mess in the middle of your HD. Best to install it on a seperate partition.
What does fragmentation level have to do with the health of the hard drive that is reported by SMART? Please explain that to me.
Since we have no idea what HD Sentinel is using to base it's "health" evaluation on it could just be flagging a performance drop which can be caused by excessive fragmentation.
It is worth checking before replacing a disk that SMARTs has not designated as failing. Since SMARTs is the criteria manufacturers use to issue RMAs for defective hardware and it is not flagging a failing drive I suspect the diagnostic tool being used before I suspect the actual hardware.
