Windows 7 RC corrupting ACLs

[phantom8]

I've been using Windows 7 RC 7100 for a few weeks. Today, I was testing sleep mode and manually put the system to S3 sleep. The system tried to enter sleep state and then the whole system hang. I rebooted the PC and found out 4 of my partitions on various disks are inaccessible. Somehow, the inaccessible partitions are being renamed as "Local Disk" by Windows.

Since my PC is configured as multi-booted and I booted it up to another Vista partition and it exhibit the same problem, 4 of my partitions cannot be accessed. I even tried to boot from Windows 7 Recovery Disc and it's the same thing.

What are the chances of a system crash resulting in corrupting NTFS ACLs (Access Control List, I think) in 4 partitions across a few disks? Here is a screen capture when I clicked on 1 of those inaccessible partition.

I can manullay take on the ownership on each partition and change all permssions on all files & directories, but this is tedius and not to mention I can't restore the permissions to their original state, since I don't know what the original permissions are for every single files on the system.

Does anyone have any ideas how this can happen? Or is it even possible to fix it?

Have you looked at advanced permissions?

I noticed the other day that my RC had suddenly added an Everyone - Deny access, to several folders on my system drive for no apparent reason.

Strange.

Did you try rolling back the OS to a time before it happened, might be worth a try.
