I have a mybook that i used to back up a bunch of stuff on my macbook. My macbook is no longer working and I’m stuck with my work pc. It’s running Windows XP pro. I’m an admin on the computer. I plug in the hard drive and it makes the sounds like it’s connecting and shows the icon to safely eject the drive, but I can’t get it to show up in my computer. Is there anything I can do to retrieve those files?

I don’t have access to another mac.

The drive does show up under Disck management.

If the drive was formatted for Mac it won’t show up in Windows. Something like MacDrive http://www.mediafour.com/products/macdrive/ might work. Sadly I don’t know of any freeware like it.
