F/BUG1
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

ANOTHER DISK BITES THE DUST!
~~~~~~~ ~~~~ ~~~~~ ~~~ ~~~~~
How I Rescued My Workdisk
~~~~~~~~~~~~~~~~~~~~~~~~~
Of all the things that can happen when you're writing a program - amongst
bugs, computer crashes and the myriad of other things that can happen - a
disk failure is perhaps the worst. Unfortunately, nobody has yet come up
with a failure proof system, so you can bet your bottom dollar that when
your reading this, somebody, somewhere, is about to commit GBH against
their computer. But when it actually happens to you, it is somewhat more
than a statistic.
Therefore, when it happened to me, sometime last week, I did not know
where to begin, or what to do (other than risk that charge of GBH). All I
knew was that I had just saved my latest game (which has since been
shelved), gone off to lunch, come back, and my so-called trustworthy
Electron gave me a remarkably unhelpful 'Broken Directory' error. All the
information my Plus 3 manual was prepared to cough up was that my disk was
in an 'inconsistent state'. Hmm, so where does that leave me? Wading
through 655,360 seperate bytes and checking each one is consistent? Thanks
for the help.
So, what did I do first? Checked I had made a backup of all the programs
on the disk, of course. I hadn't. So, what about making a backup of the
game 'Knights' which I had completed a few weeks earlier? In my dreams.
There was all of one copy of this game in the entire universe. Hmm. Two
bottles of Vodka later (joking), and I had guessed what to do. Load up a
sector editor (I used the one off of ADT) and play around with the disk. I
tried changing the BOOT option number, which is stored near the end of the
Free Space Map, Sector One. The punishment for doing this, without
updating the checksum, would have made Captain Bligh proud. I was now not
even allowed access to ADT's sector editor! I was given the error message
'Bad FS Map' (FS meaning Free Space) every time I tried. It didn't make me
feel much better knowing that even if I could cure this error, I would
still have a 'Broken Directory'.
Eventually, I tried using routines which would directly access the sectors
I wanted. This is because I couldn't see why ADT was needing to access the
FS map, when I was asking to look at something completely different. In
retrospect, I presume it was going through 'official channels', for
maximum compatibility. The routines I ended up using were from old issues
of Electron User, and written by Roland Waddilove, and they worked! The
first thing I tried to use was his Sector Editor (EU March '86), inferior
as it was to ADT's, and not only did it work, but it cured the 'Bad FS
Map' error, after I had changed the BOOT options back to what they were
originally! Now this meant that I could use ADT's editor.
Before I tried playing around again - I'd learnt my lesson already - I
used Roland's other utilities (or should that be Mr. Waddilove?) to search
for my programs using strings and such like (EU April '86). When I had
found where they were actually stored, I used another of the Big R's
programs (again, April '86) to copy them to another disk. Now I could go
on to checking what was actually wrong with my directory.
This part was probably the quickest bit of all, and was where I discovered
something that really suprised me. I was just surfing up and down my root
directory, and I learned the painful lesson that my version of ADFS was
prepared (under extenuating circumstances, of course), to save my programs
over the top of sector three onwards! Now, for the less educated amongst
us (me included), this means that the computer started saving the program
256 bytes into the root directory! Imagine that! What could I do? Well,
fortunately, it hadn't actually written over my directory entries, and the
addresses of where they exist; in other words, the last filename in my
root directory ended just before my 'saved' program started. I therefore
looked on another disk, to see what is stored after the directory names,
and most of it is just zero's, so I poked these in. At the very end of the
directory are a few numbers, to do with the options etc. of the
directory, and can be found listed in the Plus 3 User Guide. After doing
that, I found that my disk worked!
I would like to say a big thankyou to the people who tried to help me:
Richard Dimond, Bill Bradbury and 'Gus. A special thanks also goes out to
Roland Waddilove, who, all those years ago, cast in stone the utilities
which have helped me to bring you 'Knights' in this month's Game Show.
