不能加载移动硬盘，messages如下(在硬件版已发帖，因为问题只在suse10.0中出现，所以本版

现在的系统是suse10.0。在RH8.0下可以识别，＃mount /dev/sda1 /mnt/usb可以加载。在win2000下，可以识别，进入目录偶尔有”I/O错误“提示，再试可以进入。移动硬盘为日立4200转的笔记本硬盘，外面是IBM的硬盘盒。

怎么解决呢？

修改BIOS中的IRQ，给USB2.0分配专用IRQ

我进入cmos后，IRQ全是自动分配给pci的，没法改成usb。

主班是845gl,bios没刷过。

估计你的移动硬盘有可能有问题，为什么在2000下会出现IO错误呢？
