Corrupt Disk!!! Help!

Good job Digger!

I think that reinforces my claim that W7 is having trouble with disk I/O and seeing data as corrupt when it isn't.
This potentially is a very big problem and I've brought it up to some MS guys attention over at Connect. I haven't heard anything back yet but if I do I'll post about it.

I remember I also had problems back when XP was new, about how different tool used to create NTFS partitions, were not always recognized properly by the OS. Allot of 3rd party partitioning tools would create an NTFS part and the OS would want to reformat it again. I'm kinda getting the feeling that W7 is not seeing NTFS properly under certain circumstances..(?)

Be interesting to find out what is the root cause of these types of corruptions we're seeing.

Good luck Digger!

This time, well the final time I used 7 to DELETE the previous 7 partition, create new (which then automatically made it system/primary as an extended partition on Disk 0. That has stood as the answer to atleast my problem, as nothing else- including programs installed- has changed from my previous system setup and order of how i install things (old habit hard to break).

I just cant explain for the life of me why the installation does that to the HD partiton setup. Nor why formatting with a partiton while under XP makes it a corrupt install.

I let XP control and say who what when where instead of letting 7 determine and distribute how the file system is written... my opionion of sorts......... But i am still monitoring the goings on as this install is only 24 hours old now. So far so good tho.

I was trying to get you to do that when this was first reported.

Seems that 7 creates a subtly different mft than previous Windows versions. I've gotten it to "convert" by compressing an old volumes mft with Paragon Partition Manager. This forces a chkdsk at the next boot and after that, no more issues. Previously I'd avoided the corruption issues by making sure to create all partitions with Windows 7 either with the installer, Disk Management, or the diskpart command line utility.

Yay Barrod, it is doing something different alright.
That's another good idea about maybe it's in the MFT. I guess there are a number of different possibilities why 7 is seeing some data as corrupt, I can't wait to find out just what iscausing these problems.

Read the thread and make your own decision, I don't think anyone really came to a consensus. I'e maintained from the beginning that the partitioning and/or NTFS formatting that XP does is subtlety incompatible with 7 under certain conditions. I routinely use diskpart to clean, partition, format and activate exclusively. Other folks that have had the issue that followed my instructions to use diskpart to recreate the filesystem control structure on their "faulty" drives have probably forgotten all about it by now. You know you're going to need to find a place to back off that RAID array right? The operating theory is that there is MFT corruption that chkdsk won't fix. I've had good luck with Paragon Partition Manager's shrink and defrag MFT feature clearing up the issue. Other folks have needed to shrink the partition using disk manager (builtin to windows) create a new partition with windows 7 format with windows 7 and then move the data. In your case I think I'd mirror the RAID set (or sync or whatever your utility calls it) to make the disks perfect copies of each other, break the RAID array into JBOD completely clean one disk from the platters up (diskpart, clean, partition, format) copy the data to the fresh drive and the zero the other, finally recreating the array against the raw drive.
