I have Toshiba external HDD. It works fine on Vista PC. But, if I connect it to Windows 10 with a USB port, I find it's not recognized. Now, what should I do?
Have you ever encountered the same problem? Why is my external hard drive not showing up on Windows 10? What do you do if your Toshiba external hard drive is not recognized? Don't worry. In today's post, I am going to show you how to get Windows to recognize external hard drive.
As a matter of fact, the "external hard drive not showing up" issue can be caused by various reasons, including dead USB ports, driver issues in Windows, using the wrong file system, and so on. Thus, the solutions are varied. Now, keep reading to find how to fix this issue.
Solution 1 - Check USB Port and Check for the Driver Updates
In general, if Windows cannot recognize your Toshiba external hard drive, you can try connecting it to another USB port on the PC to make sure it's not a problem with that particular port. If you are connecting to a USB hub, disconnect it and try directly connecting the HDD to the computer.
On the other hand, you have to check the driver. As we know, sometimes, old drivers can cause a device to malfunction when connected to Windows.
Press Windows + R, type "devmgmt.msc" into the Run dialog, and press OK.
Expand Disk drives. Right–click the external hard drive and choose Update Driver Software…
If there are any updates, follow further instructions and your hard disk driver will be updated.
Solution 2 - Change Drive Letter and Path
Experienced users will check whether their external hard drive shows up in Disk Management when they find Windows doesn't detect it. To open the Disk Management tool, you can right-click This PC (or My Computer in Windows 7) and choose Manage in the context menu to enter Computer Management, and then select Disk Management on the left.
As we know, once the drive letter is missing, Windows cannot recognize this drive but we can see it in Computer Management window. Now, we have to assign a drive letter to the HDD to make Windows recognize it.
- Right-click the external hard drive, and choose Change Drive Letter and Paths…
- Click Add, and then pick a letter for the drive and click OK.
Solution 3 - Partitioning the Drive
If you see the external hard drive which is not recognized by Windows is full of "unallocated space," you'll want to create a new partition on it. This will allow Windows and other operating systems to recognize and use this HDD.
However, creating partition will overwrite the original data stored on the external hard drive which is not showing up. Therefore, before creating a new partition, you have to recover its lost data.
Now, I guess you might be wondering:
"How to effectively recover lost data from unallocated external hard drive with ease?"

In the main interface of Power Data Recovery, you can see 5 functional modules: "Undelete Recovery", "Lost Partition Recovery", "Digital Media Recovery", "CD/DVD Recovery", and "Damaged Partition Recovery". Different modules aim at restoring lost data under different situations.

Note: In this window, you can click Settings feature to make the program scan needed files only by file systems and file types.

Create New Partition
After recovering lost data, you can create a new partition on the unallocated space to make Windows recognize your external hard drive.
As we know, different tools like Windows Disk Management tool, diskpart commands, Free Partition Magic like MiniTool Partition Wizard, and others can help to create partition. Here, we take MiniTool Partition Wizard, a free, professional and simple partitioning software, for example. This tool not only is able to create FAT/FAT32/exFAT/NTFS/Ext2/Ext3/Ext4/Linux Swap partitions, but also can create FAT32 partitions larger than 32 GB, which can't be done in Disk Management.
- Firstly, download this freeware and install it on Windows, and launch it.
- Second, click the unallocated space and choose Create Partition option from the left action panel.
- Then, confirm parameters including Partition Label, Partition Type, Drive Letter, File System, Cluster Size, Partition Size and Location. And then click OK button to go back to main interface of the software. If you make no change here, all these parameters are kept by default.
- Finally, click Apply button on the upper left corner to confirm the creation.
When all operations are done, you will find that Windows can recognize your Toshiba external hard drive.
Solution 4 - Initialize Disk
As we know, if you connect a new Toshiba external hard drive to your PC, your Windows may not recognize it because it has not been initialized.
Open Disk Management. (Press Windows + R on your keyboard to launch the Run dialog box. Type "diskmgmt.msc" into the box and press OK.)
Right click on the name portion of the disk entry, where it says Disk [#]. Select Initialise Disk from the right-click context menu. And then, you will be given detailed operating prompts. Just do as told.
Note: during the initialization process, you'll be prompted to choose whether you want to use a Master Boot Record (MBR) or a GUID Partition Table (GPT) for the partition style of your Toshiba external hard drive. Here, in my opinion, if the capacity of your Toshiba HDD is over 2TB, you had better choose GPT, for MBR can support up to 2TB disk.
Solution 5 – Formatting It to NTFS
If your Toshiba external hard drive has been partitioned with the wrong file system, you will also encounter the "external hard drive not recognized" issue. For instance, you may have formatted the drive with the ext4 file system from Linux or the HFS Plus file system from a Mac. Or, you drive file system is damaged and shows as RAW. However, Windows cannot recognize these file systems, thus Windows cannot recognize your external hard drive.

Now, experienced users will do the following 2 things to solve this issue effectively.
First, recover important files from the external hard drive that is not detected by Windows.
Second, reformat this drive with the newer NTFS file system or older FAT32 file system so Windows will be able to recognize it.
