Short answer: It won't suddenly die, but it is starting to fail.
You should backup/move the data as soon as practically possible as bad sectors are almost always a sign of impending doom.
Ramble:
It won't necessarily die soon, but it's best to check the disk often while you're using it, just in case. Once bad sectors start appearing, they usually increase until the drive becomes unusable.
When bad sectors are discovered they are reallocated to a reserved space on the disk.
The thing is that the disk only has a limited amount of reserved space.
Once all the spare space is used, the bad sectors will ultimately end up eating into the usable space on the disk. Attempting to write data to them will ultimately result in said data being corrupted.
If the HDD was still under warranty (which it isn't) they would replace it for you.
Running the check disk utility in Windows will mark bad sectors and avoid using them.
I noticed the problem when the copy process kept crashing. I ran a disk error check with the 'find and recover bad sectors' option.
After that, the files copied successfully.
Existing bad sectors should now be marked and the disk should function normally. (for now)
Bad sectors could be the long-term result of dirt inside the HDD or manufacturing defects.
Bad sectors don't make a HDD die, but they make it less usable.
If they are continuously increasing, the outcome will be the same though.
It's likely that more bad sectors will result, so I'd say it's important to check up on the condition of the disk regularly and replace it soon.
My old 320GB laptop HDD met it's end that way. After files started randomly getting corrupted, I decided to check the disk. I found 488,284,422,393 reallocated sectors.
At that point, only about half the disk was still good, so any data written to it once it was half full ended up getting corrupted.
(You really should stop using an HDD long before it gets to this point)
Had I picked up the problem when it was just starting, it may never have come to that and I'd have been able to clone it to another HDD and keep using the laptop as if nothing had changed. (Instead of re-installing everything)
That's when I decided to start regularly checking my HDDs. That way I can have them replaced free of charge if a problem starts developing within the warranty period and avoid losing data.
This is especially true for my Anime HDDs as I have no backup of my collection.
Since it is possible the HDD may die a slow death and you may need to make plans for the data that is on it in the event that the problem escalates.
I heard some rumors about it, also about a movie... But you know how that goes.
The show had some great potential, but I think they might've ruined it with the excessive fanservice. I don't see anything officially stated about it getting a second season nor movie though.
