如果您尝试在文件资源管理器^{(File Explorer)}中打开磁盘，或者您在 Windows 11/10 设备上打开磁盘管理^{(open Disk Management)}工具来初始化磁盘，但遇到错误消息A device which does not exist was specified，那么这篇文章将帮你。

当您遇到此问题时，您将收到以下完整错误消息；

Location is not available

<DriveLetter>:\ is not accessible.
A device which does not exist was specified.

受影响的 PC 用户可能还会注意到，在设备管理器^{(Device Manager)}中，有问题的磁盘被列为未知磁盘^{(Unknown Disk)}，但是当您单击属性时它仍然可以正常工作。

指定了不存在的设备

如果您遇到此问题，您可以尝试以下我们推荐的解决方案（不分先后顺序），看看是否有助于解决问题。

1. 检查连接器
2. 在磁盘上分配完全权限
3. 卸载/更新磁盘驱动程序
4. 运行 CHKDSK
5. 将磁盘格式化为 NTFS
6. 更换硬盘

让我们看一下关于列出的每个解决方案所涉及的过程的描述。

1]检查连接器

确保^(Make)电源连接器牢固地连接到驱动器。如果没有可用的，甚至可以从未使用的驱动器（如DVD ）尝试另一个^(DVD)SATA电源连接器。

如果所有连接都正确安全但错误未解决，请继续执行下一个解决方案。

2]在磁盘上分配完全权限

此解决方案要求您在不可访问的磁盘上分配完全权限。^{(assign full permissions)}如果问题仍然存在，请尝试下一个解决方案。

3]卸载/更新磁盘驱动程序

首先，您需要卸载磁盘驱动程序，然后重新启动计算机。在启动时，Windows将自动重新安装磁盘驱动程序。检查问题是否已解决，否则，您可以尝试更新磁盘驱动程序，看看是否有帮助。

您可以通过设备管理器手动更新磁盘驱动程序^{(update disk drivers manually via the Device Manager)}，也可以在 Windows 更新下的可选更新^{(get the driver updates on the Optional Updates)}部分获取驱动程序更新。

您也可以从磁盘制造商的网站下载最新版本的驱动程序。^{(download the latest version of the driver)}

4]运行CHKDSK

如果这是触发错误的原因，您可以运行 CHKDSK 来修复坏扇区。^{(run CHKDSK )}

5]将磁盘格式化为NTFS

确保^(Make)无法访问的磁盘是NTFS 格式^{(NTFS format)}，否则您需要将磁盘格式化^{(format the disk)}为 NTFS 或简单地将磁盘转换为 NTFS而不会丢失数据。

6]更换硬盘

此时，如果您已经用尽所有可能的途径，您应该考虑更换磁盘。

希望有帮助！
