The HyperDrive manual came today. What a great manual! It was printed in 1984 and also came with an inserted addendum. Included in the manual was the default system password. To give some background, I was asked for the system password to format the entire disk. I tried "SYSTEM" and "PASSWORD" but neither worked. Oddly enough, the default system password is "SYSTEM PASSWORD" 
Luckily the original owner didn't change that password! I'm glad I bought the manual anyway and my hard disk is merrily being formatted as I type.
Here's another little nugget that someone looking may want to know (or me in the future).
How to Bypass the System Password on a HyperDrive disk:
If the disk becomes corrupt and no longer accepts the "system password", there's a way around this. olePigeon, this indicates that the system password is stored on the hard drive. Anyway, the manual tells you to do the following:
It is possible for the HyperDrive to lose all of its data so that you cannot open or create any Drawers. When you try to choose Initialize Disk in the Manager the HyperDrive asks for s System Password, but won't accept whatever you type in. (Remember, it's lost it's data, including the passwords). How can you make the Manager let you initialize the disk without using passwords?
Boot the HyperDrive from floppy disk. As you start the Manager application from the desktop, it's name "Manager" will appear in the middle of the menu bar. As soon as this appears, hold down the Command and period (.) together. Keep holding them down. Once the program comes up, a new dialog box will appear telling you the HyperDrive has not been initialized properly. You may only Format or Initialize.
The manual goes on to tell you that Initialize is a quick format but Format "re-writes the lowest level information (track and sector headers)". So now we know that Format does a low level format.
Case closed That manual is a wealth of information!
