Basically, I have a USB drive (Seagate Free Agent) and a Seagate 200 gig HDD. Originally, these were formatted as OSX extended volumes. When I decided to donate them to another PC, I used MacDrive to access them. I have since formatted them both as NTFS. After electing to reinstall Windows 7, I found to my surprise that neither drive could be read at all. It wasn't until I installed MacDrive 8 that I was able to read them once again. Why would drives that have been formatted in a native Windows volume still require MacDrive to just to be able to access them? Still waiting on support from Mediafour but I'm hoping someone here already has an answer. Thanks in advance.
