Are you able to copy out the data you need via explorer?
I would put it anywhere you can find space since the drive may not last longer.
You can upload 7gb to Skydrive with each Windows Live ID without using the Skydrive app that keeps a copy on your HD.
Later you can install the Skydrive app and have it sync those files back down to your HD, even add them to the related Library
