We all store our favorite pictures, videos, important files, folders, etc., on a hard drive. It’d be devastating to suddenly lose access to all data at once just because of a single drive error. Here we’re referring to the ‘A device which does not exist was specified’ error.

When you connect your hard drive to the system, you’d expect it to show up in the File Explorer with other system drive partitions. However, sometimes, the hard drive may throw an error showing a device that does not exist when trying to access it on the system. Feeling troublesome at such a moment is natural. But worry not! This blog will show you the best possible methods for fixing this drive error. You can also use reliable data recovery software to recover your data.

How to Fix ‘A Device Which Does Not Exist Was Specified’?

Here, we’ve curated a list of the tried-and-tested methods, considering the major reasons behind this error. Let’s begin!

#1 Check the USB Ports

First, check if all the USB ports and connections are working fine. If you see the error ‘A device which does exist was specified’ showing up with your USB or SSD, try connecting it to another system. If the drive works fine, the issue may be with the USB connection ports. If the drive throws the same error on another PC, proceed with the following methods.

#2 Give Full Access to Hard Drive

If your storage drive doesn’t have enough permission to access it, you may experience this error message. However, the permissions are usually automatically set when you connect an external/internal drive to your system. But if the permission to access the drive is not correctly configured, it may cause issues. You can try to grant full control and access to the drive with the following steps:

#3 Change the Drive Letter

Windows automatically assigns a letter to the drive when the hard drive is connected to the system. However, if the drive letter that is showing up on the error message mismatches with the drive letter in File Explorer or Disk Management, you may likely receive the error. To fix it, you’d need to change the drive letter manually. Follow the given steps:

Note: If the Change Drive Letter and Paths option is greyed out, the drive may not be read to receive a letter. It usually happens when a drive is unallocated or needs to be initialized. However, you can fix the not Initialized Drives.

Now, retry and see if the issue is fixed.

#4 Run Diskpart Utility to Re-create Disk Partition

The device may not be accessible due to partition corruption. You can try recreating the device partition using the DiskPart utility to fix the ‘A device which does not exist was specified’ error. To recreate the partition, follow the given steps:

Create partition primary

Assign letter = H

format fs=ntfs quick

#5 Update Motherboard’s Driver

Motherboard chipset drivers should be updated for all the components as they significantly impact the communication between the system and its components, including system memory, hard drives, etc. If they are outdated, they will slow down your system performance and may cause an error in a device that does not exist. You must visit the motherboard manufacturer’s site to update the motherboard chipset drivers.

However, first, check if your system has the latest chipset driver on your system. To do so, follow the given steps:

Now, check the driver’s Properties and see if the latest version is available. If not, visit the manufacturer’s site and install the latest chipset driver as per their instructions.

#6 Replace Hard Disk & Check Motherboard Headers

If all methods seem to fail, your hard drive may be faulty. If the hard drive is damaged, you may have issues connecting the device to your system. It may also lead to the ‘A device which does not exist was specified’ error. Hence, check for physical damage to your hard drive.

There is also a possibility of the motherboard header’s improper functionality. If there is some issue with the motherboard’s header, USB ports may not work, and the device may throw an error on connecting. Again, you’d need to get your system checked by experts or manufacturers to identify and fix the issue.
