Ubuntu 13.04 无法识别 USB 驱动器

使用 Ubuntu 13.04（带有 Gnome 3），我的新 USB 记忆棒（详细信息请参阅 dmesg/lsusb）不会自动显示。情况：

  • 该驱动器未显示在fdisk -l
  • 运行时确实出现驱动器lsusb
  • Windows 8 机器可以正确识别该驱动器

等待了几分钟并查看了reset high-speed USB device number 4 using ehci-pcidmesg 中的消息后，我决定拔出我的棒，这导致了磁盘读取失败。

卖家主页上的某人还表示，他无法在 Linux、Android、电视和蓝光播放器上使用该棒。有人可以给我提示可能是什么问题吗？

答案1

我正在运行 Linux mint（基于 Ubuntu 12.04）并且遇到了类似的问题。这与在哪里我的 USB 记忆棒已插入。对于某些端口，计算机认为该设备供电不足，因此不会对其执行任何操作。就我而言，U 盘已插入我的 USB 键盘。这是我所做的：

当我将其插入键盘上的 USB 端口时，键入以下内容时它不会显示fdisk -l： 尾部 /var/log/syslog我得到：

Sep 19 09:11:55 taMereIV mtp-probe: bus: 6, device: 8 was not an MTP device

我提请您注意这一行：

Sep 19 09:11:55 taMereIV kernel: [ 1789.229213] usb 6-1.3: >rejected 1 configuration due to insufficient available bus power

因此我插入了我的 USB 记忆棒直接地进入我的笔记本电脑，现在， 尾部 /var/log/syslog

特别是我的 USB 记忆棒现在显示在fdsik-l.我猜测，与 Win 8 相比，Linux 系统在确定 USB 记忆棒需要多少电量时更加保守。

答案2

您可能需要重新格式化整个分区。

答案3

如果有 USB 3.0 棒，请再等几分钟，我的驱动器 USB 3.0 挂载大约 10 分钟，这是更新后发生的，以前没问题:) 其他带有 USB 2.0 的磁盘挂载速度很快。

答案4

sdc：无法读取分区表

这意味着您的存储棒以某种方式损坏了分区表。要解决此问题，您应该使用parted和修复它gpart：

sudo apt-get install gpart

使用之前的设备 ID 打开 gpart：

sudo gpart /dev/sdc

你会得到这样的东西：

Begin scan...
Possible partition(Linux ext2), size(149660mb), offset(0mb)
Possible extended partition at offset(149660mb)
   Possible partition(Linux swap), size(2965mb), offset(149660mb)
End scan.

Checking partitions...
Partition(Linux ext2 filesystem): primary
Partition(Linux swap or Solaris/x86): primary
Ok.

Guessed primary partition table:
Primary partition(1)
   type: 131(0x83)(Linux ext2 filesystem)
   size: 149660mb #s(306504072) s(63-306504134)
   chs:  (0/1/1)-(1023/254/63)d (0/1/1)-(19078/254/63)r

假设您要恢复第一个分区，您需要获取最后一个大小值，即该分区所在的实际扇区：

大小：149660mb #s(306504072)电话(63-306504134)

一旦你有了这个，打开sudo parted /dev/sdc.您将看到一个命令提示符，键入unit sparted将数字读取为sertors。根据您之前写入的扇区数，输入：

rescue 63 306504134

parted 将开始恢复分区，并用以下内容修复分区表加您恢复可能丢失的数据。
