SMART, Reallocation events but no sectors

[Krynn72]

Just looking for some understanding with something I've seen a couple times just this week. Had a few customers drop off systems running very slow, and on three systems GSmartControl shows multiple Reallocation Events, while having no Reallocated Sectors. Why would there be events with no sectors moved? Does it suggest that the reallocation failed for some reason?

I've attached the log for one of them to show what I mean.

My experience with the Hitachi drive you listed is that the heads get weak and will start to cause read errors and slow down, while the surface of the drive is actually fine. When you cloned the drive, did it still read slowly and were there many read errors?

If in doubt, swap it out.

Yep, swapped it because I don't play with fire in situations like this and anything suspect about the drive means replacing the drive. It was from a cheapo netbook, with no data on it (he just used firefox to browse the internet) so I just did a N&P on a new drive and all was dandy.

Was this a common issue with hitachi drives of this era in general? I might go back and look into the models of the previous ones with similar issues.

The newer thin style, for sure. But, it is not uncommon for most hitachi laptop drives over the past 10 years.

For the most part if I see any red on the smart data, the drive gets replaced. Sometimes even if smart looks good, tests pass, but I have doubts about the drive, I replace it. Better safe than sorry.
