我尝试在我的 debian 虚拟机上安装外部 USB 3.0 硬盘（我使用的是 VirtualBox）。我尝试使用安装它mount /dev/sdb1/ /media/vol1/，但出现以下错误：
mount: can't find /dev/sdb1 in /etc/fstab of /etc/mtab
我尝试使用fdisk -l，得到的错误如下：
WARNING: GPT (GUID Partition Table) detected on '/dev/sdb'! The util fdisk doesn't support GPT. Use GNU Parted.

这是以下结果parted -l：
