What happened?

When I try to install Ventoy on the /dev/md0 device which uses the MBR partition table, the script did not indicate the letter 'p' to designate the partition number for RAID-0 (for example: /dev/md0p1, /dev/md0p2).
This problem also occurs in the GPT partition table.

For information: the /dev/md0 device contains 2 USB flash drives, each with 128 GB capacity storage; this allows to improve read/write speed and test the Ventoy installation on these two USB sticks using RAID-0.

LANG=C sudo ./Ventoy2Disk.sh -i /dev/md0
