I lost my installation CD

I bought my WDBAAF0010HBK-00 wd external hard drive in 2009 and have since then lost the CD that came with it. Somewhere along the lines I installed the program to free up space because I wasn’t using it at the time and now I want to use it again but like I said I lost the installation CD. Is there anything I can do?

Thats not a problem at all buddy all the downloads are free for that drive at the wdc website

heres the link for your particular drive
