上面是lspci显示的信息。配置文件里我没有添加scsi low-level drivers都没有选，系统识别硬盘的设备文件是/dev/hda  我的问题硬盘是串口sata的为啥设备文件会是/dev/hda呢？

如果你是串口sata硬盘，那为什么不选scsi low-level drivers

如果不选，那系统会用默认驱动

xs3c

谢谢楼上的回答，即便我选上scsi low-level drivers 系统依然识别的/dev/hda。在系统中有能不能看具体用的硬盘驱动？我在/sys/block/hda目录 没有看到。

具体用的硬盘驱动好像是在内核里，但具体怎么看驱动还是不太清楚

选libata了？

    没有选。 我以前一直是这样理解的 硬盘是IDE口的设备文件名识别出来应该是hd* sata口的识别出来应该是sd*。但是事实上好像不是这么回事，应该我一台机子是IDE口结果系统识别设备文件名是sd 而一个是sata系统却设备文件却是 /dev/hd。
