ESP is a very nice product and will allow you to keep that hard drive in peak shape with little or no fuss. ESP works with Windows 95/98/Windows 3.1(with DOS 5.0 or higher) and supports drives up to 8.4 gigabytes in size and you will need at least 5MB of free disk space to run it and 4MB of RAM. Take a trot over to the Partition-It Web site and give it a test drive.
