Changes are a-coming to chkdsk and NTFS health in Windows 8, and unlike the controversial Metro interface, these tweaks should make everyone happy. As hard drives get bigger, the Windows 7 chkdsk times get longer (and longer, and longer…) when hard disk errors occur, as infrequent as they are. In a worse-case scenario, attempting to boot a corrupt drive can take hours. The new system changes all that.
The Windows 8 improvements will let NTFS try to identify corruptions on-the-fly and make an instant fix in the background, no usage interruptions required. If that doesn't work, Windows 8 will conduct a "spot verification scan" to determine if the corruption is genuine or just a brief memory glitch.
Genuine errors will be reported to the user and the OS will start scan the system during idle CPU/storage times and log the location of the problems. When the scan is done, Windows 8 will prompt the user to reboot the PC at his convenience. Chkdsk will then use the information NTFS logged about the errors to fix the corruptions quickly.
"The restart is quick (adding just a few additional seconds) and the PC is returned to a healthy state," core manager Kim Bangalore writes on the Building Windows 8 blog . Hopefully it really is that quick and simple! For all the nitty gritty details and a helpful FAQ, hit the link.
