Question After a Windows 10 update, one of my disks has changed from Basic to Striped volume and fails to mount?

So I have a 2 Tb HDD that has only ever been a Simple drive, not RAID0.

After a recent Windows update the drive has changed into a dynamic Striped drive and fails to mount (when I right click and select "Reactive volume", nothing happens).

The drive is recognised in Device Manager and DISKPART.

I tried using CHKDSK, since it does not have a drive letter to associate with I ran MOUNTVOL and ran CHKDSK on the two unidentified drives (I assume this is the two drives Windows thinks are in RAID0?) and neither came back with any identified problems.

The drive is only a 2Tb but since Windows believes it is in Striped layout (RAID0?) it is looking for 2x 2Tb drives which doesn't exist (it is just the ST2000DM008 Seagate 2Tb drive in Device Manager).

My understanding is that to convert from a Dynamic drive back to a Simple drive I have to format the volume? Is there any way to resolve this without data loss?

Here is a screenshot of what I've tried:

Checking in Crystal Disk Info, no errors were reported for the 2 Tb drive "Disk 3" (the errors on the C drive are just a low count of Reallocated Sectors Count):

I also checked the same drive in SeaTools and it came back with no errors.

Thanks in advance

Hi, it can be achieved using a third party software utility without data loss. The following link can hopefully help.

Well I was able to convert it back to a simple disc, but after creating a new volume the drive isn't accessible until I format.

So I'll still lose my data?
