Docker Desktop WSL Engine fails to start due to /dev/sdd being in use #748

Bug report

Description

Docker Desktop is unable to start the Linux/WSL engine on my Windows computer.

When I start Docker Desktop, I get the error "Docker Engine stopped unexpectedly."

The main error message is:

/dev/sdd is apparently in use by the system; will not make a filesystem here!

The error occurs while Docker Desktop is bootstrapping its WSL environment and provisioning the data disk.

Steps I tried

1. Restarted Docker Desktop.
2. Ran wsl --shutdown in PowerShell.
3. Restarted Windows.
4. Ran wsl --update; it reported that WSL is already up to date.
5. Checked wsl --list --verbose and wsl --status.
6. Collected Docker diagnostics, but the engine still fails to start.

Expected behavior

Docker Desktop should start its Linux/WSL engine successfully.

Actual behavior

Docker Desktop stops unexpectedly during WSL initialization because the data disk appears to be in use.
