Change permissions on 2nd internal HDD .

I have a 2nd internal HDD that I can mount, but not access as storage.( to be precise= /dev/sda1: UUID="01BC-8D32" TYPE="vfat" PARTUUID="c72ec861-01") How do I change the permissions? Thanks all.

Vfat filesystems don't support the concept of "permissions". The apparent permissions on a vfat mount are a fiction determined by the mount options used. Remount with appropriate options and then you will have access.

mrmazda, how do I "Remount with appropriate options and then you will have access." Thank you.

It would help to know how you it got mounted the way it is, your username, and the present permissions:

Code:

mount | grep sda1
grep sda1 /etc/fstab
grep sda1 ~/.bash_history

Please place the input & output from these commands here within code tags, and include any other information you can about how it is getting mounted now.

I guess you are looking for

Code:

mount -o users,gid=100,uid=1000,umask=022 /dev/sdX /path/to/mountpoint

With gid the group id and uid the user id of owner of files.
Umask sets the default file permissions.
sdX identifies the device block to mount.

mount | grep sdc1
/dev/sdc1 on /mnt/wwn-0x50014ee1acff52b7-part1 type vfat (rw,nosuid,nodev,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro,x-gvfs-show)

Thank you mrmazda and Tonus!

Generally speaking, “foreign” file systems – if they implement any “permission system” at all – have no way to understand Linux. Unless they have been set up to use some permission structure, such as LDAP/OpenDirectory, which supersedes Linux’s scheme altogether. BTW, “you will find this concern to be generally true,” regardless of the host operating system.

In the end, ”everyone must find a way to walk around in Rome, when they are not a Roman.”
