備份光碟成iso並掛載到/media

用mount指令查詢一下ubuntu幫你自動掛載的位置

nelsonchung@ubuntu:~$ mount
/dev/loop0 on / type ext4 (rw,errors=remount-ro)
proc on /proc type proc (rw,noexec,nosuid,nodev)
none on /sys type sysfs (rw,noexec,nosuid,nodev)
none on /sys/fs/fuse/connections type fusectl (rw)
none on /sys/kernel/debug type debugfs (rw)
none on /sys/kernel/security type securityfs (rw)
none on /dev type devtmpfs (rw,mode=0755)
none on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)
none on /dev/shm type tmpfs (rw,nosuid,nodev)
none on /var/run type tmpfs (rw,nosuid,mode=0755)
none on /var/lock type tmpfs (rw,noexec,nosuid,nodev)
none on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
/dev/sda5 on /host type fuseblk (rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other,blksize=4096)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev)
gvfs-fuse-daemon on /home/nelsonchung/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=nelsonchung)
/dev/sda1 on /media/BE60E19860E15823 type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096,default_permissions)
/dev/sr0 on /media/Android type iso9660 (ro,nosuid,nodev,uhelper=udisks,uid=1000,gid=1000,iocharset=utf8,mode=0400,dmode=0500)
/dev/loop1 on /media/ebooks type iso9660 (rw)

壓縮光碟成iso的方法

sudo dd if=/dev/sr0 of=/media/BE60E19860E15823/ebooks/ISO/android.iso bs=1024

if的部份設定來源光碟位置
of的部份設定iso檔要放置的地方
bs設定大小

掛載iso的方式

先在media下mkdir ebooks

sudo mount /media/BE60E19860E15823/ebooks/ISO/android.iso /media/ebooks/ -t iso9660 -o loop
