大神们快来看看，有关硬盘挂在问题

791605975

Linux操作系统挂载硬盘，啥叫手动挂载？
设备号没有自动识别出现，能采取手动挂载么？
只能通过mount挂载么？
mount  /dev/设备号 /挂载目录 这样是手动挂载么？


接上sata之后

dev目录下没有对应设备号

q1208c

全是错误, 盘根本不能被访问. 或者是硬盘坏了, 或者是驱动不对.

791605975

硬盘挂载的驱动我在内核编译的时候已经支持了啊，是要对应硬盘型号写相应的驱动么？回复 2# q1208c

回复 3# 791605975

你能换块硬盘试试不?

你的错误是在 总线上的. 我不能确定是硬盘本身, 还是你的driver 的问题.

我换了个装了ubuntu的硬盘，能识别，不能自动挂载

你的那个Ubuntu的硬盘分区格式是什么,是不是ext4?
你的内核fs部分有没有选择支持ext4?

791605975

嗯，是ext4的格式，貌似没注意是否支持ext4的文件系统格式回复 6# chenyx


   

791605975

是在menuconfig里面修改么？回复 6# chenyx


   

chenyx

en,编译内核的时候选上

791605975

嗯，谢谢回复 9# chenyx
