Hello and welcome to Bleepingcomputer!
Yes there is a way to access the data, you would have to use a linux live cd to which you would boot to, its like an OS of its own that runs right off the cdrom or dvdrom disk, you will have to go to this web site (listed below) download the ISO Image file and burn it to a disk and boot from it, the good news is the web site has plenty of documentation on how to do the proceedure and the unix/linux section of the BC forums has tutorials and help on how to do this properly.
Once you boot from the livecd you will be able to access the files on the hard drive and save them to another media.
Here is the UBUNTU LIVECD web page to obtain your ISO image, use a free program like imgburn or CDburnerXP to burn the ISO image to a disk, all inks provided below.
