I have a spare external HD that I planned on using as my Time Machine drive, it was original formatted as NTFS and placed on one of my Win2k3 boxes. I formatted the drive last night and left it unpartitioned. When I plug the drive in to my MacBook nothing happens, and when I open Disk Utility it does not appear. When I start my MB in Vista and plug the drive in, it pops right up and Windows asks me if I'd like to format the drive.
I have futzed with this for hours now and can not for the life of me figure out why OS X is not picking up the drive when attached.
Thanks in advance for any help you can give.
Edit: Also, I used Active Kill Disk to do the format and had it completely zero the drive, took 6 hours to complete, so I don't see what's stopping Leopard from picking up the drive. *smack*
