Hi Diggsy - and welcome to the Forum.

You will find it very helpful to read the guide for new members: https://linuxforums.org.uk/index.php?board=209.0 where you will find information about the best way to post a topic. 
In particular, you should provide as much information as you can about your system.  For example, what operating system are you using?  It looks like an Ubuntu-based OS, but might be Mint. 

Assuming you are using Ubuntu, you can change the screen-blanking time by going to Settings/Power and changing the Blank Screen time. 

As for your external drives: 
1. You need to know your user ID (uid) - if you are the only user of your computer the user ID will almost certainly be 1000 but you can check by starting a terminal session and entering the following command:
Code: [Select]
uid
2. Now you need the path to your external drive.  enter the following code:
Code: [Select]
df | grep media
and look for something like /media/diggsy/device-name.  A random USB drive of mine says "/media/keith/USB1G".  At the start of that line you will see something like /dev/sdb1.  Copy this phrase.

3. Having found your uid and /dev name, enter the following code:
Code: [Select]
sudo mount -o remount,uid=1000,gid=46,rw /dev/sdb1
inserting the appropriate uid and /dev name.

This should allow you to access the device.
Please let us know the outcome.
