I scanned my hard drive with HD Tune and I'm getting the following data:

I am particularly worried about the start/stop count. What does the Data
value mean? Is that the actual number of times the disk started? That would be very high since my other drive which is just as old has only 1433
. It's so high that I'm wondering if I can even trust these values, especially since everything seems to work fine. How likely is it that I'm getting false readings?
How afraid should I be of losing all my data?
