HDD Reallocated Sector Count issue

aman6585 · May 14, 2015

I have a Seagate Barracuda 3TB HDD that is 2 years old. Recently I checked the SMART status of the drive and it showed 544 reallocated sectors. The reallocated sector count does increase by a small amount every few days. Now i've read that anything above around 20 is bad, but i'm not facing any other issues with the drive. So is it on the brink of failure or is it still safe to use till other issues show up?

Thanks

If you have data you don't want to lose, probably time to start migrating to another drive.

The numbers aren't great, but the fact that it's continually increasing is a very bad sign.

I imagine you paid a hefty price for that drive 2 years ago. It turns out to be one of the least reliable drives. You might consider the following articles before purchasing your next one.

In a Google study published a few years ago, reallocated sectors was found to be the single most reliable indicator of imminent drive failure with the majority of drives failing a few months after the appearance of the first reallocated sector.

As mrmez said, now would be a good time to start doing backups and possibly get the RMA process started if the drive is still under warranty.
