![]() For example, when I partitioned my PowerBook 5300’s 500 MB hard drive into four partitions, I instantly gained more than 30 MB of usable storage space. ![]() The solution, before Apple introduced its extended file system (HFS+)** with Mac OS 8.1 in January 1998, was to partition the hard drive into several smaller volumes, each with a smaller block size than the original single volume. However, as hard drive capacities expanded to 500 MB and beyond, the minimum file size, even for documents with just a couple of lines of text in them, became unreasonably large. This was not much of a problem back in the days when an 80 MB drive was considered large. The old Macintosh hierarchical file system (HFS)* divided each volume into approximately 65,500 blocks, which represented the highest number of data units that could theoretically be stored on the drive – no matter how large it was. What are the advantages associated with partitioning a hard drive? Well, prior to the introduction of Mac OS 8.1, the most compelling reason to partition was that it could gain you a substantial amount of hard drive space, especially on larger drives. ![]() I’m a fan of hard drive partitioning and have had four partitions on the 500 MB hard drive in my PowerBook 5300 and on the 2 GB unit in my PowerBook WallStreet G3. 2000: When you partition a hard drive, each partition functions as a separate volume and appears on your desktop with its own icon and name.
