Windows warns WD Caviar Black HDD is dying, testing shows nothing

Hi
I'm having some weird problems with one of my internal HDDs. I have 2 640 WD Caviar Black. One of them has only one partition, used only for media (music, films, photos). About 2 days ago Windows start giving warning messages about that driver.

I installed Crystal Disk Info and this is what it shows:

I start testing the HDD using Disk Check, Tuneup Disk Doctor, WD LifeGuard Doctor, Disk Checkup inside Windows and Disk Check + Ultimate Boot CD on boot to see if is something wrong but everything shows up OK. Also I changed the SATA cables and re-tested, with same results.
Now here's the weird thing. About a few months ago I noticed that sometimes, while listening to music or watching a movie(all stored on that drive) I start experiencing low FPS, sometimes even 0 & the video/audio player start freezing. And always at the same frame/minute. So I backup up all the data, tried Disk Check and formated the drive and then Disk Check again. Everything turned out OK. About 2 weeks ago I had some serious driver conflict and I posted a thread here, under driver section. Apparently, I was able to isolate the problem and fix it till a week ago when an old 250 GB IDE drive
running on an external enclosure stopped working. Windows warnings claimed that the file system got corrupted and that I need to format the drive. I tried formatting the drive but it failed since now Disk Check was run to test the drive. Also, Disk Check failed vecause the driver is not formated. So I had to use diskpart to format the drive & then I used Disk Check but everything turned out OK. When I tried to add some data on it, the problem reappeared so I had to use disk part again. Now the only applications installed were nvidia chipset drivers, after the driver issue. Also, it seams that the driver installed Nvidia Storage Driver, driver that I don't usually install. Iesterday, while trying to create an UBCD USB, I got the same weird error I got with the external drive so I had to use disk part to format it.
So, in the end, is my HDD dying or not? What does "Reallocated Sectors Count" mean?
I'm using Windows 7 Professional x64 SP1.

Kinda OffTopic: Since I bought my PC (it has almost 4 years) I changed 5 drives, this is the 6th. I made the mistake of choosing 2 Seagate Barracuda 7200.11 ES 2 ST3500320NS and 2 7200.12 and all died in the first 8 months. Anyway, in all 4 cases every testing app showed the HDDs are dying, unlike now.

So, any ideas?

Your second pic shows health status BAD, if i were you i would quit running programs to diagnose and get my stuff BACKED UP, NOW. If it's still running get everything off that drive while you still can. Then you can mess with the drive, cause when it goes it will be to late.

Haha :)) Already backing up data. I'll replace it, no doubt about it but I was curious about the fact that only 1 app detects bad status while all other apps don't. And what's weird is that Windows keeps warning me but Disk Check says it's ok. The drive is under warranty for another 2.5-3 years so it's OK.

Checking Event Viewer was the first thing to do. Occasionally I got "An error was detected on device \Device\Harddisk8\DR43 during a paging operation." Source Disk ID 51 & "The system failed to flush data to the transaction log. Corruption may occur." Source NTFS ID 57 and by occasionally I mean once or twice a day since Windows start warning about this. Done Checkdisk test on boot and inside Windows and both tests turned out clean. No errors. And I also have an identical HDD that works just fine and it has 2 years or so. That's exactly the reason I started this thread in the first place. All I have that shows HDD related issues is the warning Windows kept displaying and the BAD status inside Crystal Disk Info. Check Disk shows nothing. WD's WinDLG shows nothing. I even tried Ultimate Boot CD and it found nothing. And there are more than 10 apps inside UBCD.
And look what chkdsk returned:

You see the reallocated sectors - that is bad, especially so many. Disk drives keep a pool of unallocated disk sectors. When allocated sectors start failing on you disk, they are replenished by this pool. There are two bad things going on here. First, even though the bad sectors are being replaced, if they had data on them it could be corrupted and corrupted data copied to the new sectors. The other thing is you can replace enough sectors that none are left in the pool.

Other programs have not encountered the bad sectors as they usually have been replaced before encountered. So the fact that just the SMART data from the drive reflects the bad state of affairs is just partially chance. The fact that you also have read errors should be a warning to you s well.

I already took the drive back for testing & a possible replacement. I was asking if this might be a software issue simply because the guy kept insisting that if WD's WinDLG does not return any errors the drive is OK. Hope they won't send me back the same drive :|
