燃烧后ISO9660file-system( wodim -v dev='/dev/scd0' -sao ubcd521.iso
) 到 CD,我总是需要先弹出 CD,然后重新插入它,以便能够安装创建的 CD:
root@T42:~# file -s /dev/sr0
/dev/sr0: data
root@T42:~# mount -t iso9660 /dev/sr0 /media/
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
root@T42:~# eject
root@T42:~# #re-inserted CD tray
root@T42:~# file -s /dev/sr0
/dev/sr0: ISO 9660 CD-ROM filesystem data 'UBCD521 ' (bootable)
root@T42:~# mount | grep cd
/dev/sr0 on /media/cdrom0 type iso9660 (ro,noexec,nosuid,nodev,user=usr)
root@T42:~#
我只是想知道这是什么原因造成的?
