WD 1T not allowing transfers from Mac

Hi I’m wondering if anyone else has come across this problem I have transferring files from my Mac to the hardrive. I have a Mac book 2010, the mac recognises the harddrive and I can open things that I’ve saved on it from my pc but I can’t transfer any new files from my mac onto the hardrive. I also tried it with my friends exact same harddrive to check if it’s just mine that is faulty but the same thing happened.

Anyone else had this problem and found a solution?

The drive appears to be formatted for Windows

the Mac will read it but wont be able to write to it

you can use http://macntfs-3g.blogspot.com/ 

this app will allow you to write to the drive and avoid formatting
