Your Commodore - Commodore Is Awesome

With the Commodore disk drive it
is possible to protect files against
erasure. Any non-detetable files can be
seen in the directory with a ' < • beside
the fi le type. Unfortunately
commodore made no provision for
you to use this facility easily, this
option corrects that ommission.
I — read and change disk header or ID
This command is extremely useful
as it allows you to change the name of
any disk and its ID. You are probably
aware that all of your disks should
have a different ID. If you accidentally
formatted one with an ID that you had
already used you can change it with
this command. This saves copying al of
the files and re-formatting the disk.
The final option on this menu is 'Q'
which will take you back to the main
menu.
E) Error checker
If you should have a disk that you
suspect an error may be on then you
can use this command to find out if any
specified track has an error on it. The
type of error, if found, will be reported
then you can try to fix it with a disk
monitor etc.
F) Disk Checker
This option is similar to the aboveexcept
that it checks the whole disk
rather than asking for specific tracks.
G) File catalog
You may think that this command is
similar to the one in directory
FREE SOFTWARE
commands. It does however give you
more information.
When you perform this operation
on a disk all files on the disk will be
listed together with their start and end
addresses.
H) I.D.Checker
No doubt at some time you will have
come across files on a disk that simply
refuse to LOAD. Quite often the cause
for this is that the ID on the track has
somehow become different from that
in the ID of the DISK. This command
allows you to check the ID in all
sectors of a specified track. Once you
have found your error you can correct
it with a disk editor.
I) Load Address
This function will print out the load
address of a specified program. This is
extremely useful when used in
conjunction with menu option A as
you can find out where a program
LOADs, change it and then check it to
see if the change has been made
correctly.
J) File Scratch
Option J allows you to delete specified
files from disk. It is similar to the
standard disk 'S' command but is
much easier to use.
K) F.Unscratch
This is the File Unscratch command.
When you erase a file from disk the
actual file is not deleted it is only
YOUR COMMODORE november 1986:21
marked as being so. With this
command it is possible to re-juvinate
any file that has been accidentally
deleted. NOTE this command will
probably not work if you have SAVEd
something to the disk since the scratch.
L) W/P Disk
This command will make any disk
write protect. This command will only
work with the 1541 disk drive. The
write protect is done through software
and a write protect tab isn't needed.
However please note that you cannot
change this disk back into one that you
can write to after this command.
*) Disk Commands
This function allows you to use any of
the standard disk commands (a,s,n
etc). If you don't know how to use
them then we suggest that you refer to
your disk drive manual. 7

Warning
- LIST DIRECTORY TO THE SCREEN
As you can see this set of utilities is
extremly powerful. If you use any of
the commands without thinking then
you could possibly damage the disk
that you are operating on and be
unable to recover the data. We
therefore strongly suggest that you
back up any disk that you intend to use
this program on just in case you use the
wrong command.
A - LIST DIRECTORY TO THE PRINTER
W - WRITE INUISIBLE DIRECTORY TO DISK
- WRITE A NO DIRECTORY LOAD TO DISK
W - PROTECT FILES AGAINST SCRATCHING
LI - READ AND CHANGE DISK HEADER OR ID
W - RETURN TO MAIN MENU
