    So I opened HD Tune today to check the health as usual once in a while. The health status is now in Warning instead of OK because of the Reallocated Event Count. How worried should I be about imminent drive failure?

    It's a little disappointing since it's only 1.5 years old, and Fujitsu typically makes reliable drives. But at least the warranty is there through 2012.

    Will they replace it without a complete failure typically?

    Checked the newegg invoice, the drive is only 7.5 months old, not 1.5yrs. :(

    Personally, I would backup everything on that drive and keep using it til it dies. However, I would definitely keep an eye on both the Reallocation Event Count and the Reallocated Sector Count. The event count indicates the number of times the drive tried, and the sector count indicates the number of sectors actually moved to a spare area on the drive (note: all hard drive capacities are lies). If it stays stable, it's a one-time thing that's not the biggest of problems. If it gets worse, swap it once you get a chance.

    Thanks for the help.

    What does it mean if it's tried this many times (that's a really big number), but not actually moved any even once?

    I'd second running a battery of tests on the drive if you want to keep using it. The only reason I say it might be possible to keep using the drive is that I've had desktop harddrives throw SMART errors in the past, only to keep working for years once all the bad sectors were remapped and I did a series of zero-fills on it. I've also had drives with zero SMART errors fail for no reason. It's an area where YMMV definitely applies.

    Still, if you're not comfortable with a drive that's thrown errors in the past, replace it and put it in an enclosure til it's truly dead.

    Don't "run a battery of tests" until you've got anything important thoroughly backed-up. It may sound stupid, but if the platter is contaminated by anything, it can find its way around the drive under heavy use(including testing...). The only heavy use that drive should see right now is a thorough read, with the output going elsewhere.

    My experience of drives with bad-blocks is that they virtually always get worse. Get it RMA'd...

    That's a healthy, well-used drive with details from smartctl, which is part of smartmontools under Linux. Power-on hours = 24367 = 1000+ days of use, zero corrected or reallocated sectors.
