有时，即使在确认连接成功后，我们的 PC 也会失败或拒绝识别外部硬盘驱动器。(External Hard Drive)该问题主要发生在设备驱动程序损坏或过时时。此类问题可能很难解决。您可以花费数小时但找不到解决方案。尝试这些解决方法，看看Windows 11/10/8/7 中未检测到外置硬盘的问题是否已解决。(External Hard Drive not being detected)
为什么我的外置硬盘没有出现在我的电脑上？
如果您的外部硬盘驱动器仍然无法正常工作，您可以拔下它并尝试使用不同的USB端口。如果它已插入USB 3.0端口，您可以尝试将其插入USB 2.0端口。如果它已插入USB集线器，请尝试将其直接插入 PC，看看是否可行。
在 PC 上未显示或检测到外部硬盘驱动器
开始之前，请从端口拔下外部硬盘驱动器并将其插入另一个端口。如果它有效，也许你的第一个端口已经死了。或者，使用另一个USB并检查。如果它在两个端口上都能正常工作，那么您的USB可能已经死了。
如何修复Windows无法识别我的外部硬盘驱动器？
要修复未检测到的硬盘驱动器，请遵循我们的建议：
- 运行疑难解答
- 更新或重新安装设备驱动程序
- 在可移动驱动器上创建一个新分区
- 禁用USB选择性挂起设置
- 在磁盘管理(Disk Management)中启用并格式化(Format)驱动器(Drive)
- 尝试另一个USB 端口(USB Port)（或另一台 PC）
- 清理磁盘(Disk)并从头开始(Start From Scratch)
让我们详细看看这些。
1]运行疑难解答
您要做的第一件事是运行硬件和设备疑难解答和Windows USB 疑难解答并检查它是否有帮助。自动化工具检查连接到计算机的硬件/USB 是否存在任何已知问题并自动修复它们。
您可以通过开始搜索来搜索它们，或者您可以通过(Start Search)Windows 10 设置疑难解答页面访问这些疑难解答。
2]更新(Update)或重新安装设备驱动程序
为此，请同时按Win+R设备管理器(Device Manager)以打开“运行”对话框，输入devmgmt.msc。接下来，从列表中找到外部设备。如果您看到驱动程序出现黄色/红色标志，请右键单击其名称并选择“更新驱动程序软件...”。此外，如果您发现任何“未知设备”，也请更新它。选择“自动搜索更新的驱动程序软件”，然后按照说明完成该过程。
如果这不起作用，请卸载然后重新安装驱动程序。
这篇文章将向您详细展示如何更新或重新安装设备驱动程序。
3]在可移动驱动器上创建(Create)一个新分区
如果您之前从未将硬盘驱动器连接到 PC 并且是第一次尝试连接它，则可能无法检测到该驱动器，因为您没有为其创建任何分区。但是， Windows 磁盘管理(Windows Disk Management)工具也可以识别。因此，请验证磁盘管理(Disk Management)工具是否可以找到外部硬盘驱动器。
打开磁盘管理(Disk Management)工具，转到Search，键入diskmgmt.msc，然后按Enter。如果在“磁盘管理(Disk Management)”窗口中列出了外部驱动器，请对其进行正确格式化，以便下次将其连接到 PC 时它会显示出来。
如果您看到驱动器未分区或未分配，请格式化然后在那里创建一个新分区并查看。
如果您需要详细解释，这篇文章将展示如何使用磁盘管理工具创建新分区。(create a new Partition using Disk Management Tool.)
4]禁用USB(Disable USB)选择性挂起设置
如果上述方法没有产生预期的结果，请尝试禁用USB选择性挂起设置。这是你可以做的。
从控制面板(Control Panel)打开电源选项(Power Options)并导航到其他电源设置。( Additional power settings. )接下来，单击所选电源计划旁边的“更改(Change)计划设置”选项。
然后转到'更改(Change)高级电源设置，在USB设置下，找到USB 选择性挂起(USB selective suspend)(USB selective suspend)设置，并将其设置为已禁用。
单击应用并退出。
您也可以通过设备管理器(Device Manager)卸载有问题的驱动程序。另一种解决方案是先更改便携式硬盘驱动器盘符或备份所有重要文件，然后使用磁盘分区软件(using Disk Partition Software)格式化外部硬盘驱动器。
5]在磁盘管理(Disk Management)中启用(Enable)并格式化(Format)驱动器(Drive)
您需要使用内置的磁盘管理(Disk Management)工具检查驱动器是否处于离线模式。(Offline)打开Windows 搜索(Windows Search)( Win +S ) 并键入磁盘管理。工具出现在列表中后，单击以打开。
您应该能够在列表中看到所有连接的驱动器。在 PC 上不可用的那个将显示为灰色。右键单击它，然后选择启用。完成后，您可以格式化驱动器，使其最终出现在Windows Explorer中。
6]尝试(Try)另一个USB端口(USB Port)（或另一台PC）
USB端口可能存在描述任何硬件的问题。大多数笔记本电脑和台式机都带有多个USB端口，即使在最坏的情况下，其中一个也应该可以工作。如果USB端口被禁用，您也可以在BIOS中交叉检查，如果是，则启用它。
7]清理(Clean)磁盘(Disk)并从头(Start From Scratch)开始
如果您的 PC 上没有任何效果，那么最好的办法是连接到另一台 PC 并在该计算机上格式化磁盘(DISK)。完成后，将磁盘连接回要使用它的计算机。
如何让 Windows 11/10 识别我的外置硬盘？
在开始之前，请确保您的 Windows PC 已经过优化。通过单击 Settings app > Update & Security > Troubleshoot > Hardware and Devices > Run the Troubleshooter. 来运行硬件疑难解答。(Hardware Troubleshooter)
如果在那里找不到它，可以在提升的Windows 终端(Windows Terminal)上运行以下命令来启动硬件疑难解答。
msdt.exe -id DeviceDiagnostic
如何修复我的外部硬盘驱动器不显示文件？
如果您刚刚连接驱动器，请等待几秒钟让Windows加载所有内容。但是，如果已经有一段时间并且没有文件，您将需要在Windows中运行来自OEM或CHKDSK的(CHKDSK)磁盘检查软件(Disk Check software)来修复任何标题或主表损坏。
将驱动器号分配(Assign Drive Letter)给硬盘(Hard Disk)卷
除非为硬盘(Hard Disk)分配了驱动器号，否则它不会显示在文件资源管理器(File Explorer)中。您将需要使用Windows 磁盘工具(Windows Disk Tool)来实现此目的。
- (Type Disk)在Windows搜索中(Windows)键入磁盘，然后单击创建(Create)和格式化硬盘列表。
- 找到有问题的磁盘(Disk)，然后右键单击卷或分区
- 选择更改驱动器号(Choose Change Drive Letter)和路径(Path)。
- 完成后，文件资源管理器(File Explorer)应立即识别它。
如果您没有看到任何卷并且所有内容都显示在硬盘的黑色边框中，则表示该磁盘尚未初始化。您可以右键单击它并通过设置大小来创建分区。卷也将被格式化。
如何修复我的外部硬盘驱动器不显示文件？
如果驱动器在 PC 上可用，但看不到任何图像，请检查文件是否被隐藏。您可以使用文件资源管理器启用查看隐藏文件选项。
为什么我的外置硬盘突然消失了？
当连接设置不正确时会发生这种情况。检查驱动器连接的USB插头是否松动。(USB)如果是这种情况，您需要获得一对可以连接到 PC 的新电线。如果这不是问题，则硬盘驱动器有问题，您可能需要对其进行检查。
我的文件从 SSD 哪里去了？
如果您不是从SSD中删除该字段的人，那么它不会自行消失。检查您正在使用的程序是否从该驱动器移动到其他地方。一些外部驱动器还带有一个硬件锁，可以阻止任何类型的修改。如果你有一个这样的，然后启用它。

External Hard Drive not showing up or detected in Windows 11/10
Somеtimes our PC fails or refuses to recognize the External Hard Drive even after confіrming the successful connection. The problem occurs mostly when the device driver is either corrupted оr outdated. Such problems can be qυite tricky to fix. You can spend hours but find no solution. Try these workarounds and see іf the problem of thе External Hard Drive not being detected in Windows 11/10/8/7 is resolved.
Why is my external hard drive not showing up on my computer?
If your external hard drive is still not working, you may unplug it and try a different USB port. If it’s plugged into a USB 3.0 port, you can try plugging it into a USB 2.0 port. If it is plugged into a USB hub, try plugging it directly into the PC instead and see if that works.
External hard drive not showing up or detected on PC
Before you begin, unplug the external hard drive from the port and insert it into another port. If it works, maybe your first port is dead. Alternatively, use another USB and check. If it works fine in both ports, perhaps your USB is dead.
How do I fix Windows not recognizing my external hard drive?
To fix an undetected hard drive, follow our suggestions:
- Run the Troubleshooters
- Update or Reinstall the device driver
- Create a new partition on your removable drive
- Disable USB selective suspend setting
- Enable and Format the Drive in Disk Management
- Try Another USB Port (or Another PC)
- Clean the Disk and Start From Scratch
Let us see these in detail.
1] Run the Troubleshooters
The first thing you want to do is run the Hardware and Device Troubleshooter and the Windows USB Troubleshooter and check if it helps. The automated tools check the hardware/USB connected to the computer for any known issues and fix them automatically.
You could search for them via your Start Search, or you can access these Troubleshooters via the Windows 10 Settings Troubleshooter page.
2] Update or Reinstall the device driver
To do this, go to Device Manager by pressing Win+R together to open the “Run” dialog, enter devmgmt.msc. Next, locate the external device from the list. If you see a yellow/red sign appearing against the driver, right-click on its name and select “Update Driver Software…”. Also, if you find any “Unknown device”, update it too. Select “Search automatically for updated driver software” and then follow the instruction to finish the process.
If this does not work, uninstall and then reinstall the driver.
This post will show you how in detail to update or reinstall device drivers.
3] Create a new partition on your removable drive
If you never connected your hard drive to your PC earlier and are trying to connect it for the first time, the drive may not be detected since you do not have any partitions created for it. However, the same may be recognized by the Windows Disk Management tool. So, verify if the Disk Management tool can locate the external hard drive.
Open Disk Management tool, go to Search, type diskmgmt.msc, and press Enter. If the external drive is found listed in the Disk Management window, format it properly so that it shows up next time you connect it to your PC.
If you see that the drive is unpartitioned or unallocated, the format and then create a new partition there and see.
If you need detailed explanations, this post shows how to create a new Partition using Disk Management Tool.
4] Disable USB selective suspend setting
If the methods mentioned above do not yield the desired results, try disabling the USB selective suspend setting. Here’s what you can do.
Open Power Options from the Control Panel and navigate to Additional power settings. Next, click on the ‘Change plan settings’ option adjacent to your selected power plan.
Then go to ‘Change advanced power settings and under USB settings, find USB selective suspend setting, and set it to Disabled.
Click Apply and exit.
You may also uninstall problematic drivers via Device Manager. Another solution would be to change the portable hard drive letter or backup all the important files first and then format the external hard drive using Disk Partition Software.
5] Enable and Format the Drive in Disk Management
You will need to check if the drive is in Offline mode using the built-in Disk Management tool. Open Windows Search (Win +S) and type disk management. Once the tool appears in the list, click to open.
You should be able to see all connected drives in the list. The one that is not available on the PC will look greyed out. Right-click on it, and choose to enable. Done that, you can then format the drive so it can finally appear in Windows Explorer.
6] Try Another USB Port (or Another PC)
It is possible that the USB port may have an issue depicting any hardware. Most of the laptops and desktops come with multiple USB ports, and one of them should work even in the worst case. You can also cross-check in the BIOS if the USB port is disabled, if yes, then enable it.
7] Clean the Disk and Start From Scratch
If nothing works on your PC, then the best bet is to connect to another PC and format the DISK on that computer. Once done, connect the disk back to the computer on which you want to use it.
How do I get Windows 11/10 to recognize my external hard drive?
Before you begin, make sure your Windows PC is optimized. Run the Hardware Troubleshooter by clicking on Settings app > Update & Security > Troubleshoot > Hardware and Devices > Run the Troubleshooter.
If you cannot find it there, you can run the following command on elevated Windows Terminal to launch the Hardware Troubleshooter.
msdt.exe -id DeviceDiagnostic
How do I fix my external hard drive not showing files?
If you have just connected your drive, wait for a few seconds to let Windows load everything. However, if it’s been a while and there are no files, you will need to run the Disk Check software from the OEM or CHKDSK in Windows to fix any header or master table corruption.
Assign Drive Letter to Hard Disk Volume
Unless a drive letter is assigned to Hard Disk, it will not show up in the File Explorer. You will need to use the Windows Disk Tool to achieve this.
- Type Disk in the Windows search and then click on Create and format hard disk listing.
- Find the Disk in question, and right-click on the volume or partition
- Choose Change Drive Letter and Path.
- Once done, File Explorer should instantly recognize it.
If you do not see any volume and everything appears in the black border for the hard disk, it means the disk has not been initialized. You can right-click on it and create partitions by setting up a size. The volumes will be formatted as well.
How do I fix my external hard drive not showing files?
If the drive is available on the PC, but you cannot see any image, check if the files are hidden. You can enable the View Hidden File option using the File Explorer.
Why did my external hard drive suddenly disappear?
It happens when the connection is not set properly. Check if the USB plug to which the drive is connected is loose. If that’s the case, you need to get a new pair of wires that you can connect to the PC. If this is not the problem, the hard drive has an issue, and you may want to get it checked.
Where did my files go from SSD?
If you are not the one deleting the field from your SSD, then it won’t vanish on its own. Check if there is a program you are using that moves from this drive to somewhere else. Some external drives also come with a hardware lock that blocks any kind of modification. If you have one such, then enable it.
