A Dell Gn+, Pentium 233, PC had one 2GB partition (100% usage) created using fdisk and was running Windows '95. After installing Windows Messaging during a Novell GroupWise 5.2 installation, the user was prompted to reboot. When the system rebooted, an error of "invalid system disk" came up. Upon booting to floppy and running a 'dir' on c:\, I got a message of "file not found" even though it is reporting only about 1GB free. On closer inspection with fdisk, the partition information now shows usage at 77% (1547MB) even though total disk space is still 2012MB. How can I change the partition size back to 100% usage (and hopefully preserve the data on the drive) without having to delete the partition and create a new one?
