If this drive is a backup for Linux, then you should refomat it to use a Linux native file system like ext4. :( I'm sorry, what do I have to do again? As far as the rest of your response, I've read it a few times and I don't understand anything you said. I will only connect and turn on this external drive once a week or so (maybe less) to backup files as needed. It will be mounted automatically at boot from now on. Once the fstab is setup, just run sudo mount -a to mount it immediately. The /Data directory must pre-exist before mounting. The "big_writes" helps greatly with NTFS performance. If you need to allow multiple users to have concurrent access, then the userids will need to be in a shared unix group. The uid/gid are specific to my userid - the id command will show values you can use. I find this easier to handle for USB storage. Notice that I mount using the LABEL, not device or UUID. LABEL=250G /Data ntfs nodev,nosuid,noatime,async,big_writes,timeout=2,ui d=1000,gid=1000 0 0 The equiv fstab line would be something like: My options are:ΔΆ50G -nodev,nosuid,noatime,async,big_writes,timeout=2,fs type=ntfs,uid=1000,gid=1000 LABEL=250G You might not want to, since it is a little more complex. sudoedit is much safer than using other options like gksudo or pkexec or any sudo incarnation you may see all over the internet. To safely edit the fstab file, use the sudoedit /etc/fstab command. explains how to update the /etc/fstab for this better performance. If this will be a permanently connected storage device, then using the fstab method, with the correct mount options, can be much, much, faster. For these other file systems, either the mount needs to happen using the very slow gvfs FUSE mount technique - most GUI file managers will do this or if the fstab/autofs are used, then at mount time the userid and group must be used so your specific userid can have write access. These do not support permission changes after mount, so chown and chmod don't work. Most external disks come with either NTFS or FAT32 or exFAT file systems. Rbmorse is correct, if the partition mounted is using a Linux file system. You should now be able to read and write to the external drive. Where the username is "ron" and the external drive has the file system label "safety". You will be prompted to enter your user's password, then prompted to enter your user password again. Note the colon ( : ) between the two instances of and there are no spaces around the colon. The device identifier will either be the file system label from the external or the system determined unique device identifier. There are a couple of ways to fix this, but the easiest in my mind is to open a terminal window and execute the command (very carefully, mind): That explains why you can read and copy files from the external, but can't create folders or save files on it. If the owner is anyone other than "me" or, chances are your user does not have permission to write to the drive, only permission to read and access it. That will show you the owner of the mount point and the permissions granted for using what it contains (in this case your external drive). Right click on the folder, click on "properties" then click on the "permissions" tab. Think of it as the gateway between the folders and files on your external drive and the file system on the computer itself. The folder will be named with the label of the external's file system, or if the external drive does not have a file system label, it will have a unique device identifier that will look something like "d858727c-59fd-49a0-9d7e". If you click on it you should be able to see the contents of the external drive. You should see a folder in that location that represents the external drive. Attach the external drive, disconnect any other external storage media that may be attached, then open the file browser and navigate to:
