[问题]插入读卡器不出现/dev/sd**

#1

帖子 x671 » 2008-08-15 20:33

我一很新的1G的SD卡被我分了2个区,正常插入读卡器后应出现/dev/sdc1和/dev/sdc2还有/dev/sdc。
一直很好用,不过前两天开始插入后不出现那sdc*了,可系统监视器中一直是“IO等候”满着。
lsusb中一直有读卡器这一项,读别的卡也可以。
我打算对这个卡进行分区(或者彻底清空)操作,不过没有/dev/sdc应如何进行?
(还是这个卡出现什么诡异的问题了?)

直接没认到啊,一般应该是 sdc: sdc1 sdc2 这样的。
sdc:
事件从这句看起,只是没提示错误啊。

试试fsck或者其他手段,检查下。

系统日志中说:unable to read partition table 。
不过/dev里面没有sdc,我应该fsck什么呢?
我想分区表被破坏了,所以我想先分区,不过也没有/dev/sdc啊……
