[Coco] sdc issue

[Josh Harper]

 what I have done
drive 0,off
drive 1, "music",new
backup 0 to 1
drive  comes on and sdc starts flashing  then I get a ok prompt
then I type
drive 1,unload
then I take it to my pc
folder shows
music 
when I load vcc  vcc doesn't see the image cause it doesn't  have .dsk  so I renamed it music.dsk
then mounted it  
when I do a dir all I get is  a ok prompt
my windows has no clue what the file is
thanks for any help
