Another thing you can do is -
Make a bootable Ubuntu disk - set the BIOS to boot from optical > insert the Ubuntu disk > save settings and exit > it will then boot into Ubuntu. Use the TRY
option NOT the install and all drives connected to the machine will be there for you to open out. If it is not listed here then it looks rather like the drive is bad somehow. Download Ubuntu | Ubuntu
< you need a DVD for this. Once the OS is running (it will not interfere with your Windows OS as it is running from the disk) look for the drives - see my pic.
You can also access the net via the Firefox feature too if need be.
