DISK H cannot be mounted to DISK F
The system account was lost in disk H.
– From the result of chkntfs, we find the disk F is not dirty. The disk can be accessed normally.
– From the result of process monitor, we find VDS.exe report the one device IO control failed on the H drive. But we did not find any information related to disk F.

– We find disk F does not have the SYSTEM account. The disk information in disk management is all under SYSTEM account. If we did not have this account, we cannot receive any information about this disk. So even we can access this disk, we cannot see the value of “file system” and cannot find this disk when we try to mount to this disk.
Manually add SYSTEM account to disk F
