Re: [hard drive] WD Caviar Blue failure rates? The reason Windows wants to run CHKDSK is because the filesystem has some flags set that indicate the drive needs to be checked (usually unsafe/unclean shutdowns can cause this, but some other situations can as well).
I think this drive has some kind of mechanical problem. I've never seen a drive read all LBAs on a drive without any errors, then a few hours later begin exhibiting what you see above. The issue is not related to bad drive cache either -- it's definitely something mechanical.
My initial guess would be a misaligned head or something of that nature. Substrate problems are unlikely given the low number of power-on hours on the drive and would have shown up sooner in the drive's lifetime. There's nothing I can do aside from what I've already done WRT this drive.
My advice at this point is to RMA the drive. Don't mess around any longer with it -- just RMA it. Western Digital can/will have a fun time figuring out what's causing problems with that one.

kudos:19 | As predicted, the drive is getting worse. Some remaps didn't even work (also indicated by the write error rate), others did, and there are still even more pending. RMA away! 
For Advanced RMAs, WD often marks up the cost of the drive by 2-3x compared to retail. This is to protect them in the case they never receive the bad drive within 30 days. For example, a WD10EFRX (WD Red 1TB) warrants a potential charge of US$250, which is roughly 3x higher than the retail price. They only charge your credit card if they do not receive the bad drive.
