修复 PC 无法识别 ^{(Fix SD Card not Recognized by PC: )}SD 卡：如果您的 PC 无法识别您的 SD 卡，则问题可能与驱动程序有关。在大多数情况下，问题是由于驱动程序过时、损坏或不兼容、硬件问题、设备问题等引起的。现在，我们已经讨论过，内部 SD 卡读卡器^(Reader)或USB SD 卡读卡器^{(USB SD Card Reader)}都可能无法检测到 SD 卡这是一个软件问题，因此验证这一点的唯一方法是尝试访问另一台 PC 中的 SD 卡。查看 SD 卡是否在其他 PC 上工作，如果是，则表示问题仅在您的 PC 上。

现在这里还有另一个问题，如果您的计算机可以识别较小或较低内存的 SD 卡，例如 1 GB 或 2GB，但无法读取 4 GB、8 GB 或更高的SDHC 卡^{(SDHC Card)}，那么您计算机的内部读卡器不兼容SDHC 。最初，SD 卡最多只能有 2 GB 容量，但后来开发了SDHC规范，将 SD 卡的容量增加到 32 或 64 GB 容量。2008 年之前购买的计算机可能不兼容SDHC 。

另一种情况是您的 SD 卡被 PC 识别，但是当您转到文件资源管理器^{(File Explorer)}时，没有驱动器显示 SD 卡，这基本上意味着您的 PC 无法识别 SD 卡。因此，不要浪费任何时间，让我们看看如何在下面列出的故障排除指南的帮助下实际修复 PC 无法识别的 SD 卡。^{(Fix SD Card)}
