Automount HD Partitions.md

Fire up a terminal.

1. [IMPORTANT] sudo cp /etc/fstab /etc/fstab.old - Create a backup of the fstab file just in case something unwanted happens.
2. sudo blkid - Note the UUID of the partition you want to automount.
3. sudo nano /etc/fstab - Copy the following line to the end of the file, save it and reboot afterwards to check if it worked.
4. mkdir /my/path/tomount # to quote : "you must create the mount point before you mount the partition." see https://help.ubuntu.com/community/Fstab

Examples

A common setup is:

UUID=<uuid> <pathtomount> <filesystem> defaults 0 0

Use lsblk -o NAME,FSTYPE,UUID to find out the UUIDs and filesystems of the partition you want to mount. For example:

$ lsblk -o NAME,FSTYPE,UUID
NAME   FSTYPE UUID
sda
├─sda2
├─sda5 swap   498d24e5-7755-422f-be45-1b78d50b44e8
└─sda1 ext4   d4873b63-0956-42a7-9dcf-bd64e495a9ff

NTFS

UUID=<uuid> <pathtomount> ntfs uid=<userid>,gid=<groupid>,umask=0022,sync,auto,rw 0 0

Examples for the <> variables:

• <uuid>=3087106951D2FA7E
• <pathtomount>=/home/data/ # create this before rebooting
• <userid>=1000
• <groupid>=1000

Use id -u <username> to get the userid and id -g <username> to get the groupid.

(Note that specifying the sync option can slow down write performance as it disables the cache. async is the default.)

UUID=EEA2B69CA2B668AB /WIN_C ntfs-3g defaults,nls=utf8,umask=000,dmask=027,fmask=137,uid=1000,gid=1000,windows_names 0 0

Check UUID.md

sudo blkid.

sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL

full permission.md

How can I give full permission to folder and subfolder

Press Ctrl+Alt+T to go to a terminal and type:

sudo mkdir /var/szDirectoryName

sudo chmod a+rwx /var/szDirectoryName

HD Energy consumption.md

Umount the filesystem and then run hdparm -S 1 /dev/sdb to set it to spin down after five seconds (replace /dev/sdb with the actual device for the hard disk). This will minimize the power used and heat generated by the hard disk.

Mount all drives on fstab
