Hello kiwijery and welcome mate what you can do is to download and make a bootable Ubuntu disk (DVD).
Download and save from here http://www.ubuntu.com/download
when it has been saved burn to disk.
Set the BIOS to boot from the optical drive insert the Ubuntu disk and then when the Ubuntu OS boots up you will get an option the try or install -use the TRY
option the other option will INSTALL it!! - it will then load the OS. When fully loaded in the bottom left hand corner you will find all the drives that are installed internally and externally.
Click on the on the drive you want and then proceed to open it out as in my pic. (It is a bit like opening it out in Windows) If you need to see (or save) docs pics etc plug in a drive of some sort and just copy / paste them to that - done!
NB When you have one drive open the others will be listed at the top as well as the bottom. Some files it cannot open but mostly it can all.
Any queries post back
