"Moving hard drive
While it is possible to move some IDE PC hard drives into some model
Macintosh
computers, this is not the recommended method of transferring data and
it should
only be used by experienced computer users who understand how to
install and
format PC hard drives. It is only possible to read FAT and FAT32
formatted drives
in a Macintosh. Do not use NTFS formatted drives in a Macintosh
computer.
Mac OS X 10.3 and 10.4 work with local NTFS-formatted volumes. The
volume will be
read-only.
Warning: NTFS formatted drives cannot be used in a Macintosh (except as
read-only
with Mac OS X 10.3 and 10.4 as noted above). If you attempt to use a
NTFS formatted
disk, upon starting up the Mac OS will prompt you to format the drive.
Do not format
the drive, doing so will erase the contents of the drive. If you have
an NTFS
formatted disk, you must use another method to transfer the data from
the PC to the
Macintosh."
FAT32 is recommended here as well, for externally connected disks.

The best way to search the apple site, is not using Apple search engines.
I use
http://www.altavista.com/web/adv , set domain to "apple.com" and
enter the search terms in the top line. This method is also recommended
when searching sites having crappy search facilities such as the old ATI
or AMD.
