This WD NAS drive (WD10000D033x), which was given to me by a friend, does not have a CD (he lost it), and it still has his files on it, but in locked folders. So I need to delete his files, but have no way of doing so without being able to manage the drive. So, how do I get in to manage the drive without the CD software? I see there are downloads available but they are source files, which are no good to me without compilation knowledge, so can I manage without the CD, and if so, how? I have an Intel iMac running OS 10.9.5 and a Windows 7 PC.
Any help will be appreciated.
