Issues duplicating 8" floppies

[joshd]

It's pretty clear that there is a problem with the data  as can be seen by the flux display.  What are you connecting the drive to to use "ImageDisk" ( I am not sure what that is)?

ImageDisk is a DOS utility (read more here: http://www.classiccmp.org/dunfield/img/index.htm).  It uses a standard PC FDC to read/write floppy disks; it can read disks in a wide variety of formats (but obviously limited to soft-sectored formats written by the original 765 / WD 17xx/27xx controllers.  This is still quite a bit of media, just not things like Commodore or Apple formats...).  It's proved extremely useful (though a bit more cumbersome to use than SuperCard Pro, since I need an old DOS PC to use it.)


Specifically, I'm using ImageDisk in tandem with the FDC on an old ISA Adaptec 1540-series SCSI controller as it's quite a bit more flexible than most modern FDC controllers in PCs, but it's still just a normal 765-compatible PC floppy controller, nothing exotic.  I've read/written many 8" floppies with it and never had an issue (aside from old 8" media delaminating, but that's another problem entirely.)


Thanks,
