Since I have been interested in using disks usable by both Windows and Mac computers and found info in several other hints on this site which, however, are sometimes rather old and have a long comments section which take a while to read and new points spread in between, I thought maybe some people are interested in a short overview on what can currently be done in this area. This has saved me a lot of trouble: It is now possible to reliably read NTFS disks (NT File System, as used by modern Windows versions such as 2000 or XP) under Mac OS X 10.4 (tested under 10.4.1).
