Updates I installed in the last week or so have caused this error message to appear instead of the disk being mounted:
Error mounting /dev/sr1 at /run/media/mick/VMDVEC_ESSH_ENG1: Command-line `mount -t "iso9660" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=100,iocharset=utf8,mode=0400,dmode=0500" "/dev/sr1" "/run/media/mick/VMDVEC_ESSH_ENG1"' exited with non-zero exit status 32: mount: unknown filesystem type 'iso9660'
Also when I try to mount my USB hard drive I got the following:
Error mounting /dev/sde2 at /run/media/mick/Portable: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=100,dmask=0077,fmask=0177" "/dev/sde2" "/run/media/mick/Portable"' exited with non-zero exit status 32: mount: unknown filesystem type 'ntfs'
Prior to these problems the hard disk would only mount as read only, very useful for a back device.
where can I find the solution to these problems?
