I've just looked at the health status of my old 2,5 inch 500 Gb Fujitsu drive with a popular "HD Tune" utility. It shows a warning for the "Reallocated Event Count" property.

How serious is that?

The thing is that the drive is practically new. I pulled it out of a new laptop over a year ago and never used it since. Right now it only has 53 "Power On" hours which sounds about right since I only had it running a few evenings overnight before switching it for something more performant.

Does this warning indicate that the drive is likely to fail some time in the future? I'm somewhat perplexed since the drive is effectively unused.

What is more, I have arranged with somebody to buy off this drive since I don't really need. It is 12,5 mm thick (with 3 plates) meaning it doesn't fit into an external enclosure which makes it quite useless to me.

Can I give away the drive without having it on my conscience or better cancel the deal? In other words, can the drive be used safely for years to come or better throw it away?

I'm running a sector test now to see if there are any real problems. Will post the results as soon as they're available.
