I recently purchased my passport ultra 2tb. I connected it to MAC first to reformat it and it seems to work. However, I tried using it on my pc also but it won’t seem to work. The pc has recognized the hard drive but it won’t show up in “computer”. How can I use this in both mac and pc?

Thanks

A simple method is to format FAT32. The downside is tha largest file size it will handle is 4 Gig. A drive formatted for Windows NTFS will be read only on a Mac. See this Post #6 and see if they help  http://community.wdc.com/t5/WD-Portable-Drives/unwritable-drive/td-p/435872
