首次遇到的挂载 USB 外接硬盘的问题

mlxzlas

两块硬盘，分别为 seagate 250 sata  和 maxtor 320 ata，通过usb转接线接到装有ubuntu 6.10 的 dell D600 上，最后一次读取数据时，发现有些文件无法访问，也无法修改权限，所以就想重新挂载，但是卸载也不能，所以就 reboot 了，在 reboot 后，就无法挂载这两块硬盘了，错误信息如下：

mount: wrong fs type, bad option, bad superblock on /dev/sda1,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

两块硬盘都是 reiserfs 3.6 的单分区，出错之前都没有突然意外断电过。
请问这是什么原因造成的错误？如何解决？

nobady knows ?

发现有些文件无法访问，也无法修改权限
我遇到过
没办法重新rebuild了tree
还好找回来了一些东西
下次不用reiser了

是的，而且没有任何预兆的

rebuild-tree 损失好大啊，近500G的数据，电子书的名字全变成数字了，文档也变了，晕死............
