I bought Disk Warrior and used it 4 times successfully. Then it started telling me, before replacing the directories, that to insure a failsafe replacement, that I needed to delete 98mb of 'contiguous' space for it to do so. Neither Alsoft nor Apple can tell me how to accomplish this. Alsoft tells me I can buy their optimizer and this will take care of the situation. Sounds like a scam to me. Their current Optimizer Plus works only if one has classic 9 installed. I deleted that for "contiguous space" as I never use it and see no reason that I ever would. Disk Warrior worked fine after that for one session. Now it tells me I need to delete 100mb of contiguous space to insure their failsafe replacement. If my power is interrupted during the 20 seconds it takes to replace, I lose everything on my hard drive.
Apple sent me someting that some of you might understand about partitions and all, but is Greek to me. I can send you that, if needed.
Any help or ideas would be greatly appreciated.

P.S. How do I change my signature. The spelling is one letter off.

Disk Warrior is a great tool and helps you to manage the data in your Mac drive well. As a tool it will take space to manage your data in a proper manner and for failsafe replacement mush space is needed. But I have noticed in your post that, Disk Warrior is every time asking for more contiguous space, that means the space you have provided before is not utilized properly and that can happen due to one reason that is the contiguous space still have data whose address is not freed.
So, it is better that you erase the complete section of the contiguous space using a good wipe Mac tool, so that memory should be cleaned properly. Then use that piece of memory, I am sure Disk Warrior will not ask for more space there after.
All the best!
