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 any Mac OS 8.1 or 9.x setup in terms of efficiency. The reason is the bigger the hard drive in standard HFS (not HFS+) is, the larger small files will use. HFS Compression. It seems Install macOS High Sierra.app uses HFS compression on numerous files and it seems 10.8 has issues with that and will not “see” those files. To quickly demonstrate which files are compressed, we will use stat and examine the stflags attribute, 0=no compression, 32=compression (thanks ghost of Mac OS X Hints!).
