分区权限- chgrp不能访问

Question

我在硬盘上有一个分区，标签是“大驱动器”(参见下面的sda5 )。

Disk /dev/sda: 931.5 GiB, 1000204886016 bytes, 1953525168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: dos
Disk identifier: 0x0005a7c8

Device      Boot      Start        End    Sectors   Size Id Type

Partition 2 does not start on physical sector boundary.

它归根所有。我是管理员(Ubuntu16.04)，还有其他四个用户。分区包含文档文件。我希望每个人都能读/写这些文件夹。然而，我被推迟使用'chown 777‘命令(因为每个人都说这太危险了！)因此，尝试按照说明将所有权添加到组中。然而，这是不成功的。每次我尝试使用'chgrp‘命令时，它都无法看到分区，或者告诉我它不存在：

nevil@Desktop:~$ ll /media/nevil
total 16
drwxr-x---+  4 root root 4096 Jan  5 15:49 ./
drwxr-xr-x   3 root root 4096 Jan  4 21:20 ../
drwxr-xr-x  25 root root 4096 Jan  4 20:51 00d44d08-7c27-42d5-bb2b-0e54507b5e93/
drwxr-xr-x   9 root root 4096 Apr 12  2016 Big Drive/

nevil@Desktop:~$ sudo chgrp adm /media/nevil/Big Drive
chgrp: cannot access '/media/nevil/Big': No such file or directory
chgrp: cannot access 'Drive': No such file or directory

(我也使用UUID进行了尝试，结果也是一样的)。有人能帮忙吗？我试过用分区安装和卸载。

谢谢内维尔

空格是一个二进制位(分开的参数)。你必须把驱动器的名字用引号括起来。尝试：

sudo chgrp adm /media/nevil/'Big Drive'
