NTFS disk

Hello
We have 1 server Windows 2016 Standard with few disks NTFS
We are using Hyper-V on this server.
Now, one of the disks is stop working.
VM stop to see the disk files.
We can't copy or move file from this disk to another (could not find this item).

We can see all files in Windows Explorer.
Disk Manager see the disk correctly (Online, Basic, NTFS, Healthly)
Diskpart see the disk correctly (Online, NTFS, Healthly)
but CHKDSK display the message (The type of the file system is RAW, chkdsk is not available for RAW drive).

Could you help?
Thanks

Hi,

We can see all files in Windows Explorer - But still you can't copy files from this drive?. If you have backup of this drive, then format with NTFS then restore the files which might resolve the issue. If you don't have backup, then you may need to look for any 3rd party tool.
Are we talking physical or virtual (vhdx) disks here?
If the disk is still readable, just throwing errors, you might want to try a raw sector by sector copy to a new replacement drive.  Some software tools are available that can do that,  But I usually use a dual drive docking station with a cloning function.   There are plenty available and not very expensive.  They will copy sector by sector from one drive to another "offline"  

Here is one example:  https://www.newegg.com/Product/Product.aspx?Item=9SIA6PF3NA0586&cm_re=drive_dock-_-9SIA6PF3NA0586-_-Product
Is there a backup of the guests and their data? It may be needed.

In Disk Management click Rescan Disks found in one of the menus and see if the disk/partition indeed stays alive.

It sounds like the RAID controller, if there is one, may have hiccupped and lost the partition?

Dear all,
thanks for your replies.
The disk is physical and not in raid schema. On this physical disk I've 6 vhdx files.
In Disk Management the disk looks fine after rescan.
Thanks
