When you assign the newly-updated drive definition to your hard disk,
HDToolbox will restructure its partition information to a 'default'
setting. This will hose your partitions if you save it this way. To 
prevent data loss:

1. Enter Partitioning screen
2. Select Advanced Options
3. Click on each partition in turn and write down the beginning and
   ending cylinder numbers, partition name, bootable status
4. Exit Partitioning screen
5. Enter Define/Change Drive Type
6. Select appropriate definition (or select new definition if none is
   present and then read configuration from drive)
7. Click on Reselection box, changing it to NO
8. Select OK
9. Select new definition
10. Select OK
11. Enter Partitioning screen
12. Re-enter partitioning information for each partition, including
    partition names. beginning/ending cylinders, bootable status.
13. When it matches original info, select OK
14. Select Save Configuration to Drive
