嗨，我买了新的金士顿 DataTraveller 驱动器。我在 OS X 中对其进行了重新分区，然后转储了另一个闪存驱动器的映像。又发生了几次同样的情况，但现在当我插入它时它不会出现在任何操作系统中。以下是 Linux 中 dmesg | tail 的输出：

所以它看到了一点并将其指向 /dev/sdg
如果我使用 mount /dev/sdg /media/usb 挂载它：
mount: /dev/sdg: can't read superblock
如果我尝试使用 fdisk /dev/sdg 对其进行 fdisk 来查看分区（它没有），我会得到以下信息：
fdisk: unable to read /dev/sdg: Invalid argument
如果我尝试使用 dd if=/dev/zero of=/dev/sdg 将整个磁盘清零
dd: writing to ‘/dev/sdg’: No space left on device
1+0 records in
0+0 records out
0 bytes (0 B) copied, 0.000208433 s, 0.0 kB/s
我不知道如何删除整个磁盘并重新正确分区。有什么想法吗？
PS 在此之前，我确实设法在 openSuSe 中将其格式化为 ext2，但它引发了一堆错误，我不再记得了。Windows 也将其视为在线，但总大小为 0 字节，不允许我对其进行格式化。

要排除 USB 集线器或电缆故障，请在另一台计算机上尝试。如果错误仍然存在，则 USB 驱动器可能已损坏。
