The drive was working normally until yesterday. Today when tyring to mount from Thunar it says:
Error mounting /dev/sdd1 at /media/myname/ARCH_201511:
Command-line
`mount -t "iso9660" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,iocharset=utf8,mode=0400,dmode=0500" "/dev/sdd1" "/media/myname/ARCH_201511"'
exited with non-zero exit status 32:
mount: wrong fs type, bad option, bad superblock on /dev/sdd1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
I mabe a backup with: ddrescue -f -n /dev/sdd backup.img rescue.log
