unable to mount dongle/modem iball airways 21.0MP-58 - Ask Ubuntu

error mounting /dev/sr1 @ /media/arbind/iball airway: command-line `

mount -t "iso9660" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,iocharset=utf8,mode=0400,dmode=0500" "/dev/sr1" "/media/arbind/iball airway" mount: /dev/sr1 write-protected, mounting read-only mount: /dev/sr1 mounted or /media/arbind/iball airway busy 

it's mounted.sudo umount "/media/arbind/iball airway" first.

check device see if has hardware write-disable switch.

you can see how mounted mount | grep /dev/sr1.

if, say, it's "dongle/modem iball airways 21.0mp-58", wonder why trying mount disk.
