Hey man, Thanks a lot for your reply. What you said was very technical for me and I don't have the software to make a image. If you have time, could you give me a little more detail? Otherwise I will just re-collect the data. Thank you!
Yes, it was a rewritable CD. And I was so stupid to delete my data for this semester's work. Now I am right where I was two months ago. But thank you anyways!
