# Admin windows powershell console
GET-CimInstance -query "SELECT * from Win32_DiskDrive"
wsl --mount \\.\PHYSICALDRIVE1 --bare

# WSL
lsblk -lf
sudo mkdir /media/My\ Passport
sudo mount /dev/sdd2 /media/My\ Passport

# WSL
sudo mkdir -p /mnt/f
sudo mount -t drvfs f: /mnt/f -o uid=$(id -u $USER),gid=$(id -g $USER),metadata
