Hi, I'm going to be buying a USB2 external drive caddy to allow me to use my old hard drive from my Windows XP machine with my PowerBook. The only thing that worries me is that the partition on the drive is NTFS formatted. Is this going to cause any problems with my PowerBook getting the data from the drive, with permissions etc? Or should it be plug-and-play I can access NTFS shares over the network, but I always have to type a username and password from an account on the Windows machine to get access to the share. Thanks in advance J.
