标题: U盘在电脑上无法读取
新买的一个32GB的U盘，想要做成Knoppix启动盘，在Linux下做的过程中出现问题，然后格式化磁盘后在Linux下不能使用，用dmesg可以看到那个U盘，在windows下，win pe中都不能读取U盘，不过windows下设备管理器可以看到USB大容量存储设备！

上面分别是依次插入三个设备后的反应，第三个设备用fdisk -l命令看不到，有人知道怎么回事儿吗

重新格式化分区，fat32是目前最兼容的格式
作者: explorerlxz    时间: 2014-11-23 19:02
没有办法格式化，现在在两个系统中都找不到U盘，fdisk -l命令也无法显示，我感觉需要分析一下dmesg的输出内容，但是不太懂！

原来是U盘的问题

解决就好。。。

兄弟 你可能把u盘上自带的程序搞没了
作者: cu_shell    时间: 2014-11-24 17:46
什么牌子的U盘？。。太扯了。。真没遇到过不能做启动的U盘。。
这个U盘多半是坏的。。或者是，，对应的驱动比较稀缺。。。。
一般金士顿、闪迪的都很好用。

这个U盘也太差劲了.

自个儿量产个好？
