Autumn is, apparently, the time for the launch of new hard drive partitioning tools. We've had Partition Commander (reviewed on this site) and now it's time for the latest version of PartitionMagic. This is the program that made partition management popular - nay, practical - on the PC. Before it, apart from a couple of small shareware tools, the only way to create or re-size your hard drive's partitions was to back up all the data first, as it was sure to be annihilated.
Changing partition sizes without data loss is now as easy as falling off a swivel-chair. Why would you want to? Because, unless you're using FAT32, HPFS or NTFS, smaller partitions have less cluster wastage, since their clusters (effectively the basic unit of hard drive storage) are smaller. So a 1KB file will only consume, say, an 8KB cluster rather than a 32KB cluster, saving 24KB per 1KB file. Simple, really...
