linux下硬盘问题（DMA报错）

debian下

今天启动发现硬盘报错：

然后hdb（ext3）认不出来（换到另外一台机器上挂载没问题）。

请问怎么回事？ :ask

Maybe there is something wrong with your HDD wire?

但是过了这一段，系统（hda上的）又正常运行了，hdb（数据盘 ）显示为只读的，root都无法读写。

:help

花无影

修改grub启动项，类似下面的行，加入后面的参数：

kernel /boot/vmlinuz-2.4.21-15.ELsmp ro root=LABEL=/ ide=nodma noapic apm=off
