I have noticed the Reallocation Event Count with my internal laptop hard drive with an issue about a year ago (I don't know if it was there from any earlier) and it has been increasing ever since. I have also noticed the Raw read error rate, and the Seek error rate. However I haven't noticed any performance impact throughout the year.

This is the SMART test for your expert eyes:

Please note that this is a Seagate drive and my operating system is Windows 7.
Please tell me where the issue is and what do you recommended?

Are your reallocation events still increasing? Your drive is probably fine, but I'd keep an eye on those numbers, especially the current pending sectors and reallocated sector counts. If these last two numbers start increasing, things can go bad fast.

If you feel uncomfortable about the situation, try to get hold of seagate support and see what they have to say.

Run seatools on it. It makes no sense that the Reallocation Event Count is increasing, yet current pending sectors and reallocated sectors is zero. See SMART attributes.

Reallocation Event Count - Count of remap operations. The raw value of this attribute shows the total count of attempts to transfer data from reallocated sectors to a spare area. Both successful & unsuccessful attempts are counted

Could there be something wrong with the cable? And what about the other attributes that have values: Raw read error rate, the Seek error rate, Reported uncorrectable errors, temperature, G-sensor, Hardware ECC etc.. ?

And is this test (Seatools) data destructive?

Some of those attributes are vendor specific so are ignored. Seatools can run a SMART tests and other tests. Some are destructive, but they will list that and also warn you before continuing. Just run the smart test and the non destructive tests.

It's possible you have a bad sata cable. You can try a different cable or a different sata port.

I ran the SMART test, the short drive self test, and the short generic. All of them gave me pass score. The rest of the tests warned me about possible data lost so I avoided them. What else do you recommend?

Yes all of the values are still increasing. The reallocated sector count and the current pending sectors are still zero. I have contacted Seagate and waiting for there reply right now, so fingers crossed!
