Mac os x disk image download2/14/2023 For System 7.5.2 and newer, the maximum usable size of a volume is 2 terabytes, but this is discouraged as it then renders those drives incompatible with previous versions of Mac OS. Note: For System 7.5.1 and older, the maximum usable size of a volume is 2 gigabytes. In other words, if you're planning on using, say more than a 10GB big drive in Mac OS 9, you should totally go with HFS+ as it will contain WAY MORE files than a same size HFS standard drive. Even if you write tiny files, the remaining bytes in those blocks are totally wasted, resulting in humongous files that contain next to no DATA. The way HFS standard was implemented, there can only be limited small amount of blocks on a single drive, resulting in those blocks to distribute the hard drive space evenly and thus, be huge. Just a couple characters typed in a SimpleText document and saved on that drive will always result in a minimum size of nearly 1MB (1000000 bytes) instead of say, 8 bytes! This is due to the 16-bit blocks addressing limitation. For instance, think of a 30GB drive that you format as HFS standard (tough this would only be possible on System 7.5.2 or newer). The reason is the bigger the hard drive in standard HFS (not HFS+) is, the larger small files will use. HFS vs HFS+ quick tip from that-ben: Even tough HFS standard is highly compatible with almost all Mac OS versions, it still remains the worst choice for anything above Mac OS 8.1 in terms of efficiency.
