Hi Alan,

I don't think your read the DiskWarrior Manual first before using DW from what 
you mentioned below.

Open DiskWarrior.app  - Go to 'Help > DiskWarrior Manual' in the Menu Bar
Then when the Manual opens in Preview - Go to File > Export - & export the 
DiskWarrior Manual.pdf to your Desktop.

"What to Look for During Preview

When DiskWarrior presents the “preview disk,” you have the opportunity to check 
and test the disk as it will appear after it is rebuilt. You can run 
applications, open documents, and see if files and folders that you lost have 
been recovered.

If the original disk was visible on the desktop before you ran DiskWarrior, 
DiskWarrior will display both the original disk and the preview disk in the 
DiskWarrior Preview Window. Both of these disks will be locked during the 
preview, so you will not be able to make any changes to either of them. Both 
the original disk and the preview disk will appear within the panes of the 
DiskWarrior Preview Window.

DiskWarrior may create special folders at the root level of the disk. You 
should pay particular attention to the files and folders that DiskWarrior 
places in these folders. The folder called “Rescued Items” contains files and 
folders whose enclosing folder could not be found. If any of these files or 
folders are part of a software package, you may need to create enclosing 
folders with the correct names and locations after you have rebuilt your disk 
so that the software that uses these files works correctly, or you may need to 
reinstall the software package.

If DiskWarrior creates a folder titled “Damaged Items,” then this folder 
contains files that were recovered but may have problems. For instance, these 
files may have been truncated because blocks were missing from the file, or the 
existing directory information may have indicated that two files occupied the 
same block. The DiskWarrior Report created after the rebuild is completed will 
tell you if two files own the same block (refer to “What to Look for in the 
DiskWarrior Report” later in this document). If this is the case, then 
DiskWarrior will separate the two files for you after the directory is 
replaced. Once the rebuild is complete, you will need to determine which of 
these files can be salvaged and which has damaged data.

At this point in the process, if you discover that there are items missing from 
the preview disk, use the Find feature of the Preview Window to search for 
invisible items. Make sure the preview disk is the disk selected in the left 
pane.

In the event that critical items that you wish to recover remain missing during 
the preview, it is recommended that you do not proceed with the rebuild. Since 
the directory information for the items that are missing was overwritten or 
deleted at some point previously, DiskWarrior could not recover these items. 
You will need to send your disk to a professional recovery service to recover 
your lost files. While in preview, you should copy as many items from your disk 
as possible to another hard disk, FireWire disk, USB disk, etc., using the copy 
feature of the Preview Window. You may need to copy the original files to 
several disks, depending upon the amount and size of the files on the source 
and the size of the disks to which you are copying the files. Another option is 
to copy only the files that you absolutely need, such as those that have 
changed since your last backup, or only your data files if you are planning to 
reinstall your system and applications. In either case, it is possible that the 
Preview Window will not be able to copy all of the files you select. If the 
Preview Window displays such an error, select “Continue” to continue copying 
the remainder of the files you selected. When the copy operation is complete, 
you may want to attempt to copy the skipped files again in case the error is 
intermittent and the copy operation can be performed for those files. This will 
minimize the number of items that the recovery service will need to recover for 
you.


What to Look for in the DiskWarrior Report

After the rebuild has been completed, DiskWarrior will show you a DiskWarrior 
Report. When DiskWarrior first displays the DiskWarrior Report, it defaults to 
showing you a summary of all the problems found and repaired and DiskWarrior’s 
recommendation to you. However, if you wish to see more detail regarding the 
problems found and repaired, you can select the Details button for this 
information."
