If you can not find the USB there, you should first check whether it is visible in the Disk Management, a system utility in Windows, showing all the hard disks connected to your

You may find the USB showing up there, or it doesn't. These two scenarios need different methods to troubleshoot the USB not showing up. We will elaborate on each of these methods below.
USB drive not showing up in File Explorer but in Disk Management
If you see the USB drive in Disk Management utility, it means the system has successfully detected the drive. But due to some errors, the USB flash drive doesn't display in File Explorer. Try the following remedies to re-show up the drive.
Update or reinstall the USB driver
Drivers provide a software interface to hardware devices, including thumb drives, external hard drives, keyboards, and mouse. So, if your computer won't pick up the connected USB, you can go to Device Manager to check if the driver is working or not.
- Type and search for Device Manager.
- Find your USB disk in Device Manager from the list of USB devices and then right-click on it to choose to Update Driver if available.
- Select Search automatically for updated driver software.
- If there is no disk driver update for the USB drive, click on Uninstall Device and restart your PC, which will give your computer a fresh start to recognize USB disks.
If you can't update the USB driver directly from your system for some reason, you can visit and download it from the manufacturer's website, like Samsung, SanDisk, Kingston, and PNY.
Assign a new letter to the USB
Perhaps, the inserted USB drive has shared the same name with another volume on your Windows, which will lead to a conflict, making the system unable to show up the USB in File Explorer. Therefore, assigning a new drive letter to the USB may solve the problem.
- Run Disk Management on your computer.
- Locate the USB disk drive, right-click it and select Change Drive Letter and Paths.
- In the pop-up window, click Change and assign a new drive letter to the partition.
- Select a letter to the USB, then click Change > Ok to confirm.
Use disk repair tool
The USB disk driver is working like a charm, but why the USB drive is not showing up on your computer? Probably, the flash drive has been damaged or corrupted while you are not aware of the problem.
- Reconnect USB drive to your PC.
- Press and hold the Windows key, then press the R key to open the dialog box.
- Type in devmgmt.msc and click OK to open Device Manager.
- Locate your USB drive, right-click on it and then choose Properties.
- Choose the Tools tab and click on the Check button.
Then the built-in disk repair tool will start scanning for errors and disk corruption. When it completes, follow the onscreen instructions to fix the found problems.
Partition the USB drive
Unexpectedly, the faulty USB shows up as unallocated space, it indicates that there is no partition and file system on the USB. Such an unusable drive will not appear in File Explorer. Thus, you need to create partitions on the USB drive to get rid of the issue.
- Right-click on the unallocated space and select the New Simple Volume option.
- Click Next to specify a volume size.
- Click Next to assign a drive letter or path for the unallocated hard drive.
- Click Next to continue to format the new partition. You need to set the disk information, including file system, allocation unit size, and volume label.
Reformat the USB drive
If the file system of the USB is not compatible with Windows, it will also cause the drive not to show up in File Explorer. You can reformat the USB drive with a Windows-compatible file system such as FAT, exFAT, NTFS, etc. Reformatting will also remove file system errors and corruption issues.
But you should be aware that reformatting the USB drive will delete all the stored files on it. Therefore you should use iBoysoft Data Recovery for Windows to recover data lost and deleted from the drive as much as possible before you proceed to format the drive.

- Download and install iBoysoft Data Recovery on your computer.
- Connect the USB flash drive to the PC, and then launch iBoysoft Data Recovery.
- Check if the USB drive is detected and shows up in the software. If so, select the USB and click "Next" to scan for files and folders.
- Preview the scanning results, choose those you want to get back and click the "Recover" button.
- Go through the recovered files and folders and make sure you have all the missing files back.
Format the USB flash drive in Windows:
- Find the USB from the list, right-click on it, and choose Format from the contextual menu.
- Then set the disk information, including allocation unit size, volume label, and format.
- Click OK to format the drive.
USB drive not showing up in File Explorer and Disk Management
Unluckily, the connected USB drive shows up neither in File Explorer nor in Disk Management. That's to say, the drive is not detected nor read by the operating system in the first place. You can't see the unrecognized USB drives in any part of your computer. Check the following methods to see whether it works to fix the hard drive not showing up in Disk Management.
Check the connection

- Make sure your USB is powered on and accessible by the flashing light, physical power button, etc.
- Check the compatibility between USB and the ports to avoid device conflicts.
- Try the second USB port of your PC to connect this USB.
- Do not use several USBs simultaneously on the same USB hubs in case of insufficient power supplies.
- Try another PC or Mac to access this USB.
Enable flash drive in BIOS setup

- Use the arrow key to select Advanced, Onboard Devices, or Integrated Peripherals from the menu. Press Enter.
- Select USB Controller. Press + or - to change the setting to Enabled.
- Then press "F10" to enable the USB port and exit the BIOS.

It may be the power setting on your system that prevents the USB from showing up on your Windows. This is a power-saving feature that cuts the power to the USB when it is connected, resulting in the USB not showing up. Here is how to check:
- Open Control Panel > Hardware and Sound > Power Options.
- Under the Preferred plan, click the Change plan settings for the one you're currently using.
- Click Change advanced power settings > USB settings > USB selective suspend setting.
