Disk Copier
-----------
This utility is a single device fast data copier. Use this to copy
standard diskettes.
Disk Directory:
Shows the directory of the disk in the current device.
Device:
This is the device accessed by this module. When you enter this
module this option is automatically set to the default device specified in
"Disk Functions."
Start Track:
This is the track at which copying/verifying begins.
End Track:
This is the last track to be copied/verified.
Verify:
"No" No verify is performed during the copy process.
"Yes" The backup is verified during the copy process.
"Only" Allows you to compare two disks. With this option no write
pass occurs. For a sector by sector verify see DISK COMPARE.
Copy Disk:
Select this option to copy or verify a disk. You can abort a copy at
any prompt by pressing the escape key.
When you copy a disk you will see 3 colored bars near the lower part
of the screen, 1 bar each for the read, write, and verify (if selected)
passes. After each pass the appropriate bar will show the error status of
the pass. Asterisks '*' mean that at least one error occurred on the
corresponding track.
Notes:
As of this writing this module supports the 1541 only. If you attempt to
access any device other than a 1541 you will get a "Device not present"
error.
This utility uses the capture buffer for a data buffer. Before you copy a
disk make sure that the buffer does not contain any important information
in it or it will be wiped out!
After a copy is done you will see a "press return" prompt. When you press
return the device is initialized with the "i0" string. Make sure there is
a disk in the device that is properly formatted or a "bump" may occur. If
you copied an entire disk simply leave the destination disk in the device
and press return. If you aborted a copy, or copied only a part of a disk,
you should place a formatted disk in the device before pressing return.
Dual Disk Drive Copier
----------------------
This utility is a multi-device fast disk copier. Use this to copy
standard diskettes.
Disk Directory:
Shows the directory of the disk in the current device.
Source Device:
Place the disk to be copied in this device.
Destination Device:
Place a disk (formatted or unformatted) in this drive. The disk in
the source device will be copied to here.
Start Track:
This is the track at which copying/verifying begins.
End Track:
This is the last track to be copied/verified.
Verify:
"Read" Each block is read verified only.
"Write" Each block is write verified only.
"R/W" Each block is read and write verified (full verification)
"None" Nothing is verified.
Copy Disk:
Select this option to copy a disk.
Notes:
As of this writing this module supports the 1541 only. If you attempt to
access any device other than a 1541 you will get a "Device not present"
error. Before you use this utility you should make sure that the
destination device has been used since power up. This will avoid a
possible "bump" at the start of the copy process. Why a "bump?" The 1541
has no way of knowing where the read/write head is until it accesses a
disk. From that point on the device "remembers" where the head is located.
Finding the first track for the copy is simple math. If the first track to
be written is track 1, and the head is currently at track 2, the routine
simply moves the head 1 track. If, however, the device wasn't used since
power up, the head could be anywhere, so the DOS routines in this module
turn control over to the 1541 to perform its built-in "seek" function in
order to determine the head position. In this case, a seek done on an
unformatted disk will cause a "bump" (OUCH!)
Nibbler
-------
This utility is a single drive disk nibbler. Use this utility to copy
DOS protected 1541 diskettes.
Disk Directory:
Shows the directory of the disk in the current device.
Device:
This is the device accessed by this module. When you enter this
module this option is automatically set to the default device specified in
"Disk Functions."
Start Track:
This is the track at which copying begins.
End Track:
This is the last track to be copied.
Track Increment:
This option is normally "1.0" for full-track stepping. You can set
this option to "0.5" to copy "half-tracks." For example, if this option is
set to 1.0 and your start track is 1.0, you will copy tracks 1.0, then 2.0,
3.0, etc. If the track increment was 0.5, you would copy tracks 1.0, 1.5,
2.0, 2.5, etc.
Header Gap Size:
This option allows you to set the header gap size for the destination
disk. The header gap provides spacing between the header block and data
block. The standard header gap length is 8 bytes. Although this option
allows you to vary the header gap size from 1 to 16 bytes, you should not
use any value other than 8 unless you are sure you want a different size.
The standard dos format uses an 8 byte header gap.
Tail Gap Size:
This option allows you to set the tail gap size. The tail gap
provides spacing between the end of a data block and the start of the
header block of the next sector (inter-sector spacing). There is no
"standard" tail gap size, as the tail gap is dependent on the speed of your
drive. The standard dos format command will use a value of at least 4, but
not more than 12 bytes.
Copy Disk:
Select this option to nibble copy a disk. You can abort a copy at any
prompt by pressing the ESCape key. When you copy a disk you will see 2
colored bars near the lower part of the screen. The green bar shows which
tracks have already been read from the source disk. The red bar shows
which tracks have been written to the destination disk.
Notes:
This utility uses the capture buffer for a data buffer. Before you
copy a disk make sure that the buffer does not contain any important
information in it or it will be wiped out! After a copy is done you will
see a "press return" prompt. When you press RETURN the device is
initialized with the "i0" string. Make sure there is a disk in the drive
that is properly formatted or a "bump" may occur. If you copied an entire
disk simply leave the destination disk in the drive and press RETURN. If
you aborted a copy, or copied only a part of a disk, you should place a
formatted disk in the drive before pressing RETURN.
As of this writing this module supports the 1541 only. If you attempt
to access any device other than a 1541 you will get a "Device not present"
error.

block. The standard header gap for a 1541 is 8 bytes. Although this

should not use any value other than 8 unless you are sure you want a non-
standard size.
