The OS will support it. But Rob will need to divide it in several partitions, because MacOS versions prior to 8.1 don't support partitions of more than 2 Gb (or 4 Gb in the case of System 7.5.4 -I think- and System 7.6.x). > I > know that older PC (not intended as flame bait) BIOS and DOS configurations > had limits at 32 MB, 540 MB, 2 GB, and 8 GB. A little comment on this, even if I may be a bit off-topic :-) . The 540 Mb, 8 Gb and 127 Gb limits affect only to IDE/ATA/ATAPI drives - they are limitations of the very old (and lame) hardware and software interfaces defined for accessing the hard drive in the PC. On the other hand, the 32 Mb and 2 Gb limits are caused by the different versions of the FAT16 filesystem. The Macintosh also have the very same limits in ProDOS and HFS partitions (see above), and because of the very same reasons: addressing the blocks with a 16-bit integer allows up to 65,536 blocks by partition; multiply that by 512 bytes (the standard sector size) or 32 Kb (the largest amount addresable by a signed 16 bit integer), and you'll get, respectively, 32 Mb and 2 Gb. Oh, and Windows NT also raises the limit to 4 Gb on FAT partitions, because it does the same trick as System 7.5 and 7.6: using *unsigned* integers to address the data in the blocks in order to achieve 64 Kb blocks :-) . As different as the IBM PC and Apple Macintosh may seem at a first glance, it's amazing how many things behave the same way on both of them!
