Hard Drive Not Showing Up in Windows
 

Part 1: Fix for HDD (Old/New) Not Showing Up in Windows 10

Applies To: Fix the issue of an internal or new hard drive not showing up, not being recognized, or not detected in Windows 10/8/7.

Here, we've rounded up 6 methods for you to try. Depending on the current state of your hard drive, choose the appropriate method and follow the instructions to get it showing up again:

For a used hard drive, try fixes 1, 2, 3, 4, and 5. If your new drive isn't showing up, try fixes 3 and 6.

Let's start fixing the “hard drive not showing” error on our own:

Fix 1: Change Disk Connection – Resolves the issue of the hard drive not showing up in File Explorer

Applies to: Fix issues where an internal hard drive or new hard drive isn't showing up in File Explorer or Disk Management.

Connection issues are usually due to faulty cables or loose connections. Here's how to fix your hard drive connection so it shows up on your computer, and you can also resolve the issue of not seeing files or folders on an external hard drive in Windows 10.

Step 1: Check the cables. If the power cable or SATA cable is damaged, replace it.

Step 2: Firmly disconnect and reconnect the hard drive with its SATA cable and power cable.

Step 3: Restart your computer and check if the drive appears.

Solution 2: Format the hard drive to NTFS – Fixes issue with undetected hard drive with RAW or corrupted file system

Applies to: Fix the hard drive not showing up issue due to unsupported, RAW, or corrupted file system.

When your hard drive shows up as RAW or “*Other” in Disk Management, it means that your hard drive has a file system error.

In this case, the best solution is to format the drive to a supported file system. To do this:

Step 1: In Windows 10/8, press Windows + X and click on 'Disk Management'.

In Windows 7, right-click the Start icon and select “Search.” Type in disk management, then click it.

Step 2: Right-click on your drive and select “Format.”

Step 3. Choose NTFS as the file system, check the "Quick Format" box, and then click "OK" to begin formatting the drive.

Format Hard Drive

Note: Since formatting will lead to data loss, do not forget to use a data recovery tool to retrieve all your hard drive data after Step 3.

Solution 3: Recover Data and Create New Partition - Fix Unallocated Hard Drive Not Showing Issue

Applies to: Resolving issues where the hard drive is not showing up but appears as unallocated or unknown, or a new hard drive shows as uninitialized in Disk Management.

If your hard drive suddenly becomes unallocated, it might be due to accidental deletion, a virus attack, or some unknown reason that led to the loss of partitions on the disk.

You should attempt to recover data from the unallocated space first, and then create a new volume on the disk so that the drive becomes visible again.

Method 1: Recover Data from an Unallocated Hard Drive

Professional hard drive data recovery software like Data Recovery Wizard can thoroughly scan for lost partitions and recover your files from unallocated disk space.

The software will mark unallocated space on the disk as a lost partition, so you can simply select it for scanning and find everything that was on the drive:

Step 1: Select the disk where you lost data and click on “Scan”.

Select and scan the hard drive

Step 2: After the scan, use the "Filter" or "Search" option to look for the lost files.

Preview Lost Hard Drive Data

Step 3. Select all the files you want to recover and click on “Recover.” Next, browse and choose a different secure location to save them.

Recover Data from Hard Drive

Before you make the drive appear again and ensure that it's safe to save files to, make sure to save the recovered files to a different secure location. If you can't fix the issue yourself, you could also turn to a professional Data Recovery Service.

Step 1: Right-click "This PC," select "Manage," and then click "Disk Management."

Step 2: Right-click on the “Unallocated” space and select “New Simple Volume…”

Step 3: In the New Simple Volume Wizard, click Next to continue.

Step 4: Specify the size of the volume, assign it a drive letter, set the file system to NTFS, and click “Next.”

5. When Disk Management shows that it has created a new volume on the hard drive, click “Finish.”

Fix 4: Change the Hard Drive Letter - Resolve disk not showing issue due to drive letter conflict

Applies to: Fixes an issue where a hard drive doesn't show in File Explorer due to drive letter conflict or no drive letter assigned to the hard drive.

When your hard drive letter conflicts with another drive on your computer, it will show up as "New Volume" in Disk Management. As a result, it won't appear in File Explorer.

The best way to make a hard drive show up, then, is to change its drive letter. Here's how:

Step 1: Right-click on the unallocated hard drive partition, or the one marked as “New Volume,” in Disk Management.

Step 2: Select "Change drive letter and paths". In the new window, click "Change".

Step 3. Assign a new drive letter to your external or internal drive, and click “OK.”

Change drive letter

Fix 5: Update Disk Drivers - Resolve hard drive not showing issue caused by outdated disk drivers

Applies to: Fix the issue where a hard drive is not showing up in File Explorer. There's a yellow exclamation mark on the hard drive in Disk Management.

If you see a yellow exclamation mark on your hard drive under “Disk Drives” in “Device Manager,” it means that the driver is outdated. As a result, the hard drive won't show up in File Explorer or Disk Management.

The only solution is to update the driver, and here's how:

Step 1: Right-click on "This PC" and select "Manage".

Step 2: Click on “Device Manager,” and then expand “Disk Drives.”

Step 3: Right-click on the external or internal drive in question and select “Update driver.”

Step 4: Click on Search automatically for updated driver software online.

Update the hard drive driver in Disk Management

Wait for the driver update to finish, and then restart your computer. After that, you can check if the hard drive appears.

Fix 6: Initialize the disk, create volumes, and enable in BIOS – Fix for new hard drive not showing up issue

Applies to: Fixes an issue where a new hard drive doesn't appear in File Explorer.

Most of the time, if you have a new hard drive, you need to initialize it first and then create a new partition on it, and enable it in BIOS so that your new hard drive will show up in Windows 10/8/7.

Step 1: Initialize the disk and create a volume on the new hard drive

Step 1: Right-click on "This PC" (in Windows 10) and select "Manage."

Step 2: In Disk Management, right-click your new drive and select Initialize Disk.

Step 3: Select the disk, then choose MBR or GPT as the partition style, and click "OK" to begin.

Initialize a new hard drive

4. Right-click on the “Unallocated” space on your new drive, and select “New Simple Volume.”

Step 5: Set the volume size, drive letter, and NTFS file system for the new hard disk.

Step 6: When you're done, click Finish.

Step 2: Enable the hard drive in BIOS

If the hard drive is disabled in the BIOS, the operating system won't detect it, causing it to not show up in Windows. Therefore, it's necessary to check if the hard drive is disabled in the BIOS.

Step 1: Restart your computer and press F2 or Del to enter the BIOS.

Step 2: Use the arrow keys on your keyboard to select Integrated Peripherals and press Enter.

Select Integrated Peripherals in the BIOS

Step 3: Use the arrow keys to highlight “USB Controller”

If it's disabled, change this option to Enabled.

Enable the new hard drive in BIOS

Step 4. Save the changes and exit the BIOS.

Then restart your computer and see if it detects your hard drive.

Why isn't my hard drive showing up on my Mac?

The reasons for a hard drive not showing up on a Mac are very similar to the reasons a hard drive won't show up on a Windows computer.

Here's a list of possible reasons why a hard drive might not show up on a Mac: 1. **不兼容的文件系统**: 如果外部硬盘使用的是Mac不支持的文件系统(如FAT32或NTFS),它可能无法被识别。Mac OS X原生支持HFS+和exFAT。 2. **连接问题**: 确保硬盘正确连接到Mac。如果使用USB线,尝试更换线缆或使用不同的USB端口。对于Thunderbolt或FireWire驱动器,检查连接是否牢固。 3. **驱动器未初始化**: 如果硬盘未经过初始化或格式化,Mac将无法读取它。打开“磁盘工具”并尝试初始化硬盘。 4. **硬件故障**: 硬盘可能存在物理损坏,导致无法在Mac上显示。这可能需要专业人员进行诊断和修复。 5. **电源问题**: 如果是外接硬盘,确保它有足够的电源供应。某些硬盘可能需要独立的电源适配器,而不仅仅是通过USB供电。 6. **驱动程序或固件问题**: 硬盘的驱动程序或固件可能已过时或存在错误。访问制造商的网站以获取更新。 7. **OS版本不兼容**: 某些硬盘功能可能与特定版本的macOS不兼容。确保你的Mac运行的是最新版本的操作系统。 8. **磁盘空间已满**: 如果硬盘空间已满,它可能不会在Finder中显示。清理一些空间应该可以解决问题。 9. **逻辑错误或坏道**: 硬盘可能存在逻辑错误或坏道,影响其正常工作。使用“磁盘工具”的“验证磁盘”和“修复磁盘”功能来检查。 10. **隐藏或禁用的卷**: 有时,硬盘的分区可能被隐藏或设置为不可见。在终端中使用命令行工具(如`diskutil list`)来查找隐藏的卷。 如果以上方法都无法解决问题,可能需要专业的数据恢复服务或联系硬盘制造商的技术支持。
