Put the drive back into the Windows machine

and format it as NTFS.

Put it back into the Mac and use Disk Utility to format it as Mac OS X (journaled).

That is if the idea is to use the drive exclusively for the MacBook.

If you were thinking of using the drive in both machines, just buy one for each machine
