Peter,

I thought the old XT's had a BIOS lo lvl format which you could jump to in 
DEBUG  something like G=C800:0005 ? Interleave used to be 3:1
But best to check in the Norton Utilities manuals!

Other possibility is Track 0 on new drive is corrupt - there's a fix for 
that too, but I don't remember exact details. You copy from a good drive.
The program to write track 0 is short & dangerous. I suggest you
check _exact_ details in in Norton Utilites manuals - sure it's in there
somewhere. I had the same fault on an antique Epson PC a few years back.

Hope this helps. Sorry it's a bit vague, but I'm sure NU has details.

Regards,
