I have installed ubuntu on my internal hard-drive using windows ubuntu installer and everything worked perfectly. I am able to run both windows7 and ubuntu.
I also have an external hard-drive which I only keep for data. At first, I could access the data (mainly pictures and music) from both ubuntu and windows7. Now, when I open it in windows7, it's doesn't show anything. It shows indeed that it's half full but I see no folders or files. From ubuntu I can open it perfectly, no problems there.
My question is: how can I make windows see the data from my hard-drive again? I don't really care about ubuntu recognizing it. I only use ubuntu for my homework.
Thank you in advance!
