Filesystem is now RAW

This is weird.
I was going to run a chkdsk on the D:\ drive of our server and got an error saying: "CHKDSK is not available for RAW drives". So i checked "My Computer" and D:\ drive is listed as NTFS filesystem, as well in the drive properties.

Users are still able to access network shares from the drive and im just worried that this might break sooner or later.

D:\ is another partition on a RAID-5 configuration.

any help would be appreciated.
It would be hard for us to do "tests" and "reboots" etc right away as it is on a remote location and this is the file server... but will try anything that could fix this.

thanks in advance

I can research for you why the drive is listed as RAW. But I need you to install and run once Drive Backup 10 Server Edition trial on this server: http://www.paragon-software.com/business/db-server/
No need to reboot the server. Just download trial - install it - run it - see if product detects your drive as RAW.
Then close the program and get to C:\Program Files\Paragon Software\Drive Backup\Program and find there STUBACT.log and BioNTlog.txt files.Upload them here.
I will look through geometry of the drive and check if it is correct.

what do i need to run on the program?
or do i just go to the "Disk View"?

In Disk View, yes it says "D: - Not Formatted"

oh my, i'm getting kinda nervous here.. :(


I've attached the 2 files.

thanks again!

From the first glance everything look ok. No geometry issue. What did you use to create this partition? Was it Windows created?
I have sent the log file to my contact person at paragon support. Will let you know if they find anything. For me it now sounds like corrupt file system.
The quickest solution is to copy out everything from D: drive to USB or network. Then delete the partition Disk Management. Or with Drive Backup and create new one NTFS formatted. Delete and create but not simply reformat.
Or wait for feedback.

Yeah, we just used Windows when we first set it up about 3-4 years ago..
This just happened yesterday when our backups were not able to backup the D:\

Its weird that they are still able to access the shares and permissions are still in tact...

I'll wait for the response from Paragon support and hopefully there's something we can easily do to fix this rather than copying everything to a USB as there's about 800GB+ of files and users are continually working on them..

thanks for your help! we'll wait for your response.

The problem you have is when you try to sort this, it could end up making the drive completely inaccessible, which is a nightmare on your part. I'd look at copying everything you have on there ASAP while its still working.

If there are lots of different user group security permissions that you want to keep on the files / folders, you can use robocopy to keep this:

robocopy [source] [dest] /MIR /R:1 /SEC

/MIR = Mirror Dir
/R:1 = Only retry failures 1 times
/SEC = Copy security

You could drag-drop thru Win but if the file / folder structure is very large, that's not advisable.

Ok got feedback from the representative. He requested HDD and partition first sectors. You can save them via same Drive Backup 10.
Start DB10 - right click on your HDD where the RAW partition is located. Then select View\Edit sectors.
You do not need to change anything there, simply find at right option Save to file. Save sector 0 to .bin file.
Same operation for RAW partition - right click on it - View\Edit sectors - save to file.
See attached screen shots.

Please change the extension from .zip to .bin as we're not allowed to upload .bin files.

Ok report is here. First a question: do you use any encryption tool on this server? Because partition first sector is a garbage. That's why you see the partition as RAW in Windows and Paragon.
Can you save the last sector of partition and send it also?

noxchoGlobal Support CoordinatorCommented:
Press the drop down - select the mover and move it to the end. There must be on the top right pane a word NTFS (see my example).

no we do not use any encryption tool on this server
i've attached the file.
so how can we fix the first sector, is deleting the partition and reformatting it, the only way?

**Please change the extension again to .bin**

thanks.

Ok, the last record is ok. Now you need to restore the last sector over first one. With the same View\Edit sectors. Keep the first one at hand in case this does not help you will need to restore it.
Run Drive Backup - Right click on RAW partition - View\Edit sectors - select Load Sectors from file and point it to the Prtition-LastSector.bin file. The load key is next to save key.
Apply changes and refresh Drive Backup. Does it resolve the problem?

sorry i have been away for the last couple of days.
so if i restore the last sector to the new one. does it screw up any files/folders/security,etc.??
do i have to restart the server after applying restoring?

yes, we do have a backup of data for this drive.

noxchoGlobal Support CoordinatorCommented:
It will simply overwrite the first sector of the partition. You do not need to restart the server. Just restore the sector file and refresh the program.
It does not screw up anything. If this won't work simply restore the backup of first sector of partition over the one you took from the end.

ok, thanks for the responses.
i have some questions in regards to sectors of a partition..

1. Are the first and last sector supposed to be the same?
2. Can you further explain why/how would restoring the last sector to the first sector would work and fix the issue?
3. Would there be any difference if it was on a RAID partition and a physical hard drive partition?

thanks again.

noxchoGlobal Support CoordinatorCommented:
1. Are the first and last sector supposed to be the same? - Yes. NTFS partition keeps copy of boot sector at the end of partition.

2. Can you further explain why/how would restoring the last sector to the first sector would work and fix the issue? - Your first sector of RAW partition is corrupt. In short there is total mess. This happens in two cases: a)encrypting software is used to prevent security violation. b)Due to file system error or rootkit the first sector got screwed up. Now we are going to replace it with a copy saved by careful Microsoft =)

3. Would there be any difference if it was on a RAID partition and a physical hard drive partition? - No. Partition sector is located on logical level of the drive not physical. Actually file system does not know if you are using RAID.

on the restore sector part, its asking me this:

Please select start sector - default is "0"
Please enter number of sectors to restore: - default is "1"

Do i need to change anything there?
