Seagate External HD Failing?

I got a Seagate 1.5 TB external hard drive (ST1500LM003) about 2 and a half years ago. Turned on HD Sentinel and it gives it a health percentage of 14% with "112 bad sectors". It also says "276 errors occurred during data transfer". Not sure what that means since I've transferred files all the time back and forth and nothing has become corrupt (as far as I know). The only thing that sometimes happens is that it disconnects and reconnects from the computer randomly.

I tested it and the Short DST failed, Short Generic passed.

When I did a surface test, there didn't seem to be more problems than the ones stated. 112 sectors seems to be a tiny percentage.

Since I'm not an expert on hard drive health, I pose the question: Should I get a new drive? I'd rather be safe than sorry... but I'd like to know if the drive is actually much more likely to fail, or if it the risk increase is just tiny.

Thanks in advance.

If you replace the cable and it is still reading as bad sectors then yes, if it was a faulty cable making the software believe you had bad sectors when you didn't then no. Also make sure that is the proper cable for your E-HDD. But if it still reads as bad sectors after trying a new cable it needs to be replaced, bad sectors are a sign of a HDD failing and so it is only a matter of time before the drive completely fails(if it isn't just a bad cable causing all this)

So no matter how small the number of bad sectors, the fact that they even exist means that I should replace the drive in your opinion?

Bad sectors won't get better, only worse.

So it's more likely that more bad sectors will occur rather than it just staying the way it is you think?
