I have just bought an 250 GB external USB/Firewire drive to use it to
receive image backups of my hard drive (both Mac and the BootCamp
partitions) using SuperDuper or CarbonCopy. The drive came already
formatted in FAT32, so it can be seen from a Mac or from a PC.
I'd check to see what your chosen Mac backup program requires - some
require HFS.
But I understand that FAT32 drives have a limitation, they cannot
handle files larger than 4 GB. So, do these Mac backup programs
segment their backup files in smaller chunks, in order to bypass this
problem?
There are two limitations on FAT32 drives - one is how big of a drive
the newer versions of Windows will format (I think that's 4GB), and
the other is how large it can be - I believe 160G iPods will format in
a single FAT32 drive.
The Windows 2000 format utility will go to 32 GB.
Windows 98 format utility will go to 127.53 GB.
Microsoft is pushing NTFS here.
Checking http://en.wikipedia.org/wiki/File_Allocation_Table shows a
possible 8 TiB volume size.
