Can't mount CDROM after sys copy to new HD
 

Recently I copied my Debian Filesystem to a new HD. Only thiong that doesn't work is the CDROM. I had super mount on fstab like this:

none /cdrom supermount fs=auto,exec,ro,--,users 0 0

and changed it to:

/dev/cdrom /cdrom iso9660 ro,user,exec 0 0

removing supermount, in case this was the prob.It's not.

mounting it like this:

# mount /dev/cdrom /cdrom

It returns: mount: /dev/cdrom already mounted or /cdrom busy

I don't mind not having supermount, although it would be nice, can anyone help me please?

SYS Config: Duron 700MHz, 80Gb HD, 40x ATAPI CDROM, 360Mb RAM, KErnel: 2.4.25, Debian.
