So.. I contacted G Skill about this already.. They said 'its normal, and that it may just reduce the maximum size of the drive'...

Here's the MSG from SpeedFan via it's SMART analysis..

"NOTE : your hard disk has 19198 offline uncorrectable sectors (this value is very large and your hard disk should be replaced). Those are sectors that an offline scanning found as unreadable. Offline scanning is a process that can be automatically started by the hard disk logic when a long enough idle period is detected or that can be forced by some tool. Those unreadable sectors are identified and the hard disk logic is waiting for a write command that will overwrite them to try to remap them to spare sectors (if available). A simple disk surface scan won't be enough to force the remap operation. You need a read/write surface scan to remap the sector. The best option should be a tool that knows about what should be read from that sector so that it has some option to apply the best fix to the missing data.

The overall fitness for this drive is 0%.
The overall performance for this drive is 100%."

I've read up a bit about this wiper.exe but cannot confirm if by using this it wipes the entire drive or just the unused?

My drives performance is sitting around as it should be.. Write around 200 mb/s at higher files sizes, and 250mb/s reads. As rated for this drive.

I don't appear to be losing out performance wise.. But the number above (the offline sectors) rises slowly over time... I formatted this drive and upgraded the firmware as was asked by G Skill and it went back to 0... Only to reach this number again in a few months.. Anyone else ever have this issue? Is it normal for an SSD or is it time to swap over to OCZ? :P

Hey Mjolnir, I know this an older thread, but I figured that I'd throw some information in. I use an OCZ SSD drive in my server, and ever since it was put in, it started complaining about "Uncorrectable Offline Sectors", just as yours has. From my understanding, they are using this entry as something else. Normal SMART readers interpret this value as "Uncorrectable Offline Sectors", but it could be anything they want it to be.

I also noticed that mine is increasing. Never had an issue with the drive, but I keep a close watch. The smartd daemon on my server watches and gives reports if it notices a drive failing. I can add an exception for this drive, but I'd rather watch to see what happens.

Thanks for the reply! Finally got one :P. Sounds like it's just a normal SSD thing then? Doing a clean wipe/format/re-firmware of the drive seems to wipe it all. So I shouldn't worry about it until my drive starts dying? (Hopefully it doesn't anytime soon :P)

[thideras]

Since the makers are not releasing information, there won't be an easy way to tell what it is. In the drive, it is just a value (such as 0x56), so it doesn't mean much. I've seen a few threads on OCZ when I got my drive and I was researching what was "wrong". There were a few threads where OCZ staff responded with (basically) "That isn't what you think it is, don't worry about it" and refused to give more information.

So, bottom line: I don't know.

[Mjolnir]

Fair enough. Basically what G Skill told me. "it's normal, don't worry about it". Okay...

Meh. I've yet to notice any issues with my drive performance wise, so whatever! =D. Loving the SSD!!! Makes my AMD system seem even slower than it already is! (At least compared to my sig rig... It's a x3 720, HD 4870, Seagate Momentus XT HDD).

The momentus XT was a bit of a let down.. Didn't seem nearly as snappy as I'd hoped. Oh well! Thanks again for the reply!

[thideras]

No problem. I'll respond if I start having issues or it explodes. I don't think it will have issues.
