Maya exhaled. Data loss was expected. But was the file mountable?

She navigated to the database folder. The main MDF was intact. Two log files were zero bytes. She ran a quick CHKDSK /f on the virtual drive, then used a VHDX recovery tool from the Microsoft Store——to scan for orphaned file fragments. It pulled back 92% of the client’s transaction logs.

But she remembered a buried forum post from 2019. She opened and attached the VHDX manually—first as read-only.

She detached the VHDX, then re-attached it normally. This time, the drive letter appeared with a file system: NTFS.

It was 11:47 PM on a Tuesday, and Maya’s phone buzzed with the kind of alert that makes IT pros go cold: “Hyper-V host storage corruption detected.”

No error. The disk mounted but showed as “RAW.” Not good. But it meant the header was still alive.

By 2:18 AM, she had copied the recovered data to a brand new VHDX, reattached it to the VM, and booted the SQL server. The logs showed a clean shutdown recovery.
