We have a 2000Server Domaincontroller. boot and systempartion are on one drive. A second hard drive contains Powerquest Multicast software and a lot of images (in .pqi format)
After noticing that restoring images has slowed down I inspected the state of fragmentation on this harddrive (230 GB) and found 50 - 60% fragementation. So i decided to Deragment with the intenal Windows tool from 'Disk manager' The tool has finished but i LOST my shers to the drive!. after rebooting Diskmanager says Disk 'healthy' but it's no lnger formatted so i cannot acces it. It looks "all my data has lost"
Recover programs cannot restore the data.

The issue is that i did exactly the same defragmentation on a other separate system that contains the same configuration (Domain controller and seperate 230GB data drive)That acts as spare system.
Unfortunally the result was the same ALL DATA on the second harddrive lost after deragmentation. I have solved very lot of problems. But such as this never happened
I have a big disaster ! Can anyone help me????

What you need to do right now is to copy the whole disk to another disk (make that two disks), so that if anything goes wrong you will have the back ups. Does the drive(s) in question have a drive letter in "Disk management"?. If not (do this AFTER you have done the back up) give it a drive letter and see if the drive can be accessed.
Another thing you can try is the "restore" option.

Please post back if you have any more problems or questions.

Sorry, your solution did'nt work.
The case is that the disk with most important data is detected by 'Disk manager' and signed with the normal drive letter and as 'Healthy'. Nevertheless the disk is not accesible properties shows no hidden systemshare (wich should be) and is saying that the disk is not formatted. There is no file system showed which should be NTFS.
This is exactly the spontanious state after simply defragmentation. Neverwhere i can find information about such a phenonema. It's sure that all the information is still there but also your methode can'nt unlock it.
A new 'by windows' suggested format of the whole disk is certenly NOT what i intend to do!! you can imagin why.
Thank anyhow for your respons! Is there anyone else with a good suggestion???

Restore tools that i tried (even spinrite) will only restore some information but NOT our critical data (.pqi files) They will restore a good NTFS MFT but it is not the solution.
Me be we need i tool like un-defragmentation. Just the opposite of the problem cause.

A small bit of info on it.

How It Works

QA Disk Repair works in a few easy steps. All you need to do is selecting the hard drive to repair or recover files from, and let QA Disk Repair scan the drive. After the scan is complete, you'll be presented with a list of recoverable files, and will be able to preview each of them before deciding to save one. QA Disk Repair will only attempt to repair the disk system structures after it safely backs up all your important files onto a healthy media such as a different hard disk, flash memory card, recordable CD or DVD, or a remote network or FTP location.

I would make a copy of the drive first, and then test this out on one of the drives.
I had similar but on a smaller scale, i formatted the drive and used this type of software and i had (nearly all) my files and folders back. To which i got more disks to do back ups on so this does not happen again.
Hope this works out for you.
