Linux and Win8: Fast Startup puts data at risk

From H-Online:

The new Fast Startup feature of Windows 8 puts the filesystem's integrity at risk if other operating systems are used to write to Windows partitions. Data loss is particularly likely with dual-boot configurations that involve Linux and Windows 8.

Those who frequently use both operating systems are advised to disable the Windows 8 Fast Startup feature.

The risk of data loss through Fast Startup or Hibernate doesn't only exist with parallel Linux/Windows installations, it also arises when a live version of Linux is booted – for example from a USB flash drive, CD or DVD.

Details at site.

Just to clarify, this is nothing NEW... anyone who dual booted, after hibernating windows (or - wait for it - OSX), and then dual booted the machine to linux, and mounted the file system of the hibernating OS in Linux, and wrote to it... will royally hose the hibernating OS since it's not expecting the disk to change under it while it's "gone". This, as they say, is pretty freaking obvious.

Solution: Don't hibernate if dual booting and mounting the partition in both OSes. Yes, you can disable fast boot and hibernate in win8. A child (or a linux admin) could do it.

Now if they could just teach a Windows admin to do it

windows admins don't run Linux.

how does fast startup work? I am guessing it is saving some kind of system state data that gets messed up if the FS is written to externally.

its a hybrid hibernate where the user space is dumped but kernel space ram is saved/restored to a hibernate file. so the kernel doesn't expect (and is totally hosed when) the disk to change, as it has cached disk info...

ahh gotcha, so in way it would be like moving the records around in a juke box but not telling it. When its powered up again it thinks Bohemian Rhapsody should be at C3 but instead it gets Hotel California.

see File systems and parties are the same though. free beer can generally repair both.

Is this the real file, or is this just junk you see?
You can chkdsk any time you like, but you can never read.

That's just wrong.
