真郁闷，mount iso文件出错？？？

freegnu

下了个iso文件，发现其md5校验码不一致
想看看内容：
mount file.iso point -o loop
提示：
mount:you must specilfy filesystem type

molucule

你加上-t iso9660试试

freegnu

mount -t iso9660 file.iso point -o loop

mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       or too many mounted file systems
       (could this be the IDE device where you in fact use
       ide-scsi so that sr0 or sda or so is needed?)

freegnu

好像文件坏了，能修复吗？
