Microsoft Redesigns chkdsk For Windows 8, Improves NTFS Health Model
MojoKid writes "Microsoft can't do anything to magically make hard drives stop failing when parts go bad, but Redmond is rolling out a new NTFS health model for Windows 8 with a redesigned chkdsk tool for disk corruption detection and fixing. In past versions of the chkdsk and NTFS health model, the file system volume was either deemed healthy or not healthy. In Windows 8, Microsoft is changing things up. Rather than hours of downtime, Windows 8 splits the process into phases that include 'Detect Corruption,' 'Online Self-Healing,' 'Online Verification,' 'Online Identification & Logging,' and 'Precise & Rapid Correction.'"
...sounds like M$ is copying spinrite.
Right up until your primary gets some corruption and proceeds to mirror it to the other.
It still hangs at 100% CPU for no apparent reason even after 20 years.
Just delete an important file or directory on a RAID1 and see how much that "backup" protected you. Or install a virus. Or have data corruption on a disk.

Seriously. Your strategy puts at risk all the writes during that rebuild process.
That only "backs up" against drive failure. What happens if something gets deleted? What happens if a process goes mad and scribbles all over something important? What if someone breaks in?
For large sets, this will be our guide even unto death, for the LORD will work for each type of data it is applied to...
RAM is cheap. Why not use it?
Can you be Even More Awesome?!
If there is one thing you can count on in the world, it's someone screaming "RAID is not a backup!" at the top of their lungs in any conversation dealing with RAID.
Yes, thank you. We get it. RAID does not protect against deleted files, etc. You can go back to shouting other contrarian favorites in other threads.
In the mean time, if and when one of the drives in my RAID-1 mirror fails, I'll be sure to throw its working partner straight into the garbage can. I certainly wouldn't use it to restore my entire filesystem that would have otherwise been obliterated.
I don't know about you, but I'm constantly deleting files by accident, and getting personal data destroying viruses (via a time machine from the 90s) where as my drives never, ever fail.
