You need a bit level copier program to try and copy them, either on a BBC or
a PC with correct software.

I don't think XFER will work for you.

I would think Line 1350 is the Line Number in the XFER programming which is
failing to read/copy the disc, and hence give this error.

Line 1350 probably has a disk copy function or file copy function.

Thanks for the replies to my earlier questions.

I am now having a problem copying a Protected Disc. 

The original disk is a factory produced disk 40 track DSDD. The second side
is blank. I have three (factory) copies of this and the all behave the same.
There is a file called CNCDRAW, I am unsure of it's function as If I try to
load it, it gives the same disc error as below.

Essentially there are two problems:
1) I am using ADI200, to copy these there seems to be some skewing of the
sectors and tracks 33&34 have no sectors. Apart from that I can see no other
problems. When I copy these they copy fine and verify fine. When I run the
program (menu driven CNC program) it loads and runs fine, but when I ask it
to load a specific file into the CNC simulation it gets errors and exits to
the prompt. On the original disk this does not happen.
What are the settings you would recommend and any advice would be
apprieciated.

2) When trying to XFER the disc to PC I get the following listing
$.CNCDRAW              000000  000000  002000  00A
Then it says transferring and the file size is 3062. It makes a noise as if
the drive is on the wrong track setting and comes back with this error
DISC FAULT AT :0 0F/00 AT LINE 1350
If I switch the drive over to 80 track when it makes its noise I get the
following error
DISC FAULT AT 0 0E/00 AT LINE 1350

Now for some other info that may or may not be helpful. I have some software
written by the same company for a CNC milling Machine, it is on a 80 track
disc DSDD but these have hand written labels Indicating that they were
copied. It also has this CNCDRAW file (but the file size is smaller at 2560)
and it gives exactly the same problem when trying to xfer it across. The
error I get is the same for the 40 or 80 track switch setting: DISC FAULT AT
0 01/00 AT LINE 1350

Is the "LINE 1350" referring to the XFER ? or to the file its trying to
transfer?

I don't have these discs for long as they need to be sent back on tues/wed
this week.
