CURE: Try each of the following until the problem is fixed.
1. Replace the HD-20's Finder File:
a) Turn on the HD 20. Switch off Macintosh, insert
Hard Disk 20 Startup Disk in the internal disk drive,
and switch the Macintosh on again.
b) When you see the "Welcome to Macintosh" prompt, hold down
the mouse button until the Finder is completely displayed
(the wristwatch turns into a pointer).
c) The Hard Disk 20 Startup disk is now the current startup
disk. Display the contents of the System Folder on the
HD Start-Up disk. Select the Finder file and go to the "File"
option on the menu bar to "Get Info" for revision information
on the Finder file. It should be revision 5.0 or better
d) Display the contents of the System Folder on the
Hard Disk 20 to ensure that the HD 20's Finder and System files
are located there. If they aren't, find them on the HD 20 and
move them into the HD 20's System Folder.
e) If the HD 20 Start-Up disk's Finder file was an
acceptable revision, drag it over to the System Folder
on the Hard Disk 20, replacing the old HD 20 Finder file.
f) Reboot the HD 20 Start-Up disk and recheck for the problem.
If it still exists, go to step 2.
2. Rebuild the HD-20's Desktop:
a) Simultaneously press the COMMAND, OPTION and TAB keys while
you reboot the HD 20 Start-Up disk.
b) The Finder should ask if you want to intialize the HD-20.
Make sure you select "Cancel" for this operation or you
will lose all of the data stored on the HD 20.
c) The Finder will then ask you if you want to rebuild the
DeskTop file. Select OK. After the finder rebuilds its
desktop, recheck for the problem. If it still exists,
go to step 3.
WARNING: If you perform step 3 below, all data will be erased from the Hard
Disk 20. This solution should be used as a last ditch effort, for a truely
mangled hard disk.
3. Initialize the Hard Disk 20
a) Press the COMMAND, OPTION and TAB keys while you reboot the
HD 20 Start-Up disk.
b) The Finder should ask if you want to intialize the HD-20.
Select "OK". This operation erases all of the data stored
on the HD 20.
Note that these methods will cure failures due to software Finder problems and
will not get at hardware problems that may the the original cause of the
problem. When finished with the above procedure, run the HD 20 Test located on
the Startup disk on the hard disk.
