Root not working - Can't install Ventoy

[longpanda]

Hi,

Well, I'm using Linux Mint 20 Cinnamon and trying to install Ventoy but I just can't. I Should be able to do it with root privileges but isn't working anyway.

Even as root user it says " Failed to access /dev/sdd, maybe root privilege is needed!" 

The script just use dd to read data from /dev/sdd to check that whether we can acess the disk.
You can run the dd cmd manually.

Code:

if dd if="$DISK" of=/dev/null bs=1 count=1 >/dev/null 2>&1; then
    vtdebug "root permission check ok ..."
else
    vterr "Failed to access $DISK, maybe root privilege is needed!"
    echo ''
    exit 1
