I broke the disk into two logical volumes. In one volume, had an operating system. In the second volume of stored programs. Then I needed to increase the size of the system drive. What I did: 1. Booted from installation disk. 2. Remove the second partition. 3. Increased the size of the first (system) disk. 4. Check the disk and partition for errors. Result: 1. What sees "Disk Utility": 1.1 Size section increased 1.2 The size of free space has not changed. Capacity 99,9 GB, Available 1,1 GB, Used 39,0 GB 2. What sees Finder: 1. Size of the volume has not increased 2. Size of free space has not increased.
