感谢darrenlee ,问题初步解决。
如您所述,确实插入的时候报错了。
sigmav sigmax6 # dmesg| tail
scsi24 : usb-storage 8-1:1.0

执行hdparm -z 之前 fdisk -l 状态不变
cannot access /dev/sdb1: No such file or directory
执行hdparm -z /dev/sdb
/dev/sdb:
re-reading partition table
再进行挂载
sigmav sigmax6 # ls /dev/sdb1
/dev/sdb1
sigmav sigmax6 # mount /dev/sdb1 /mnt/udisk/
成功,并且可以看到里面的内容。
这里有两个疑问。
1、 既然hdparm读取能够正常识别,为什么插入的时候不能直接识别呢? 目前每次都要执行hdparm才能挂载。
2、 我用的thunar-volman进行自动挂载 这好象是和udev有关,之前又一次居然识别出来并且正确挂载了(只出现过一次),目前十分不解。 |
