PowerQuest--the inventor of on-the-fly hard-disk partitioning software--has revved up its PartitionMagic software to give Windows XP users improved control of their hard drive and other data storage resources on their PCs. PartitionMagic 7.0 is scheduled to be available next week for a suggested retail price of $69.95. Current users can upgrade previous versions for a $49.95 fee. It is the first application to qualify for Microsoft's Designed for Windows Logo Program. "PartitionMagic, with its enhanced NTFS support, will help users experience the full benefits of Windows XP," says John Fredericksen, general manager for Windows marketing. The new PowerQuest software enables users to create multiple partitions of various sizes and configurations on hard drives. Officially, the software handles drives up to 80GB in size, although company representatives say the new version can partition hard drives larger than 140GB without problems. The updated software also supports USB drives, so you can access and manipulate external drives with the same ease as your hard drive.
