我需要在存储卡 (CompactFlash) 上创建一个分区。我买了一个USB 存储卡读卡器，并插入了一个 512MB CF。控制台消息（见下文）表明该卡被识别为 /dev/sda，但它没有挂载，并且“fdisk -l”和 gparted 都没有显示该设备。我是否必须先采取一些特殊措施？我正在运行 Ubuntu 22.04。
以下是我取出 CF 存储卡并重新插入读卡器后看到的消息。最后一行重复了很多次：

我在启动时也看到了以下几行：

更新：我插入了另一个坏驱动器，它似乎产生了磁盘错误。我拔下它并重新插入我的存储卡读卡器，不再看到错误或重置消息，但我仍然无法访问该驱动器。我只看到：

答案1
正如@Terrance 所说，问题出在适配器坏了。我买了另一个一模一样的，用起来没问题。
