How to Fix “A device which does not exist was specified”?
When you connect a drive to your Windows computer, you would normally expect it to appear in the File Explorer window where you can access the drive and store or retrieve your files. In some cases, however, upon trying to access the drive using the Windows Explorer window, users get the “A device which does not exist was specified” error message which prevents them from accessing the drive. Though the drive appears in the Windows Explorer window, there is no additional data shown under the drive which is something you would normally expect. That is, the size of the drive and the free space information is not given.
A Device Which Does Not Exist Was Specified Error Message
As it turns out, upon opening the Disk Management tool in Windows, in some cases, you might notice that the drive letter is not actually correct compared to what’s shown in the Windows Explorer window. If this scenario is applicable, you can work around the issue by changing the letters and then restarting your computer. However, that may not always be the case and in some cases, the issue can be related to the drive permissions in which case you will have to check them and make sure that you have full ownership over the drive. To understand the error message in question better, let us have a look at the possible causes of the issue before jumping into the different solutions that can help you resolve the issue.
Now that we have gone through the possible causes of the error message in question, without further ado, let us get into the various solutions that you can implement to resolve the issue and access your drive.
Change USB Port
As it turns out, the first thing that you should do when you face the error message in question is to change the USB port that the drive is connected into. If you are using an internal drive, then this isn’t for you and you should move onto the next method down below. More often than not, a faulty USB port can cause the issue that you are facing and a simple switch of the USB port fixes the issue. If you have plugged the drive into a USB 2.0 port, try connecting it into a USB 3.0 port and vice versa to see if that resolves the issue.
USB Ports
Change Drive Permissions
As we have mentioned above, another cause of the problem could be the drive permissions. This happens when your user account does not have sufficient permissions to access the drive and as a result, you are shown the drive is inaccessible error message. In such a case, you will simply have to change the permissions of the drive via the Properties window and that should resolve the issue. To do this, follow the instructions given down below:
Uninstall Device via Disk Management
As it turns out, in some cases, the issue can be resolved by a simple restart of the device. This can be done by first uninstalling the device via Disk Management. Once you do that, Windows will be forced to install the required drivers for the drive again when you plug it again. That has reportedly fixed the issue for some users and might do the same for you. To do this, follow the instructions given down below:
Change Drive Letter
The error message in question can be triggered by an incorrect drive letter in some cases. When you plug in a drive to your computer, the operating system assigns it a drive letter that is used to access the drive and the files inside it. If the drive letter is incorrect, you will be unable to access it which is why the error message is shown. This can be easily resolved by changing the drive letter via the Disk Management tool. To do this, follow the instructions given down below:
Update BIOS and Chipset Drivers
Chipset drivers are also known as motherboard drivers are really important. These drivers are responsible for the components that you plug into your motherboard so it is really important to make sure that they are up to date. In case you are outdated, you can potentially face issues such as this one. If this case is applicable, you will have to download the latest BIOS and chipset drivers available for your motherboard from your manufacturer and install them.
The process is not complicated and you will usually find a tutorial on your manufacturer’s website. There are also utilities available that automatically update the drivers on your motherboard so you can make use of them as well. Therefore, go ahead and search for your motherboard’s drivers by typing in the model that you are using. Follow the tutorial given on the website to install them and then see if the problem persists.
Check Motherboard Headers
Finally, if none of the above solutions worked out for you and you are using an internal hard disk that connects to your motherboard SATA headers, it is possible that one of the headers may be faulty which is why you are not able to access the drive. In such a case, you will have to open up your PC and then change the headers. It is recommended that you take it to a technician if you are not well versed with motherboards because it can get complex.
Fix Error 0x800701b1, A device which does not exist was specified
Some Windows users are seeing Error 0x800701b1, A device which does not exist was specified when trying to copy, paste, or move files from or to an external Hard Drive connected via the USB port. In this article, we will be seeing how to resolve the error with some simple solutions.
What does Error 0X800701B1 mean?
The Error Code 0x800701B1 forbids the user from accessing some features of any external Hard Drive that they have connected via a USB port. There are many reasons for this error, such as outdated or corrupted driver, use of USB 2.0, some glitch, etc. But the worst-case scenario is still corrupted Hard Drive. We will see how to know if your Hard Drive corrupted hereinafter. We will be talking about all of them and more in this article.
Error 0x800701b1, A device which does not exist was specified
Let us talk about them in detail.
1] Use a Different Port
Some users were able to fix the issue by connecting their external Hard Drive to USB 3.0 instead of USB 2.0. There is a very obvious reason for it. USB 3.0 is superior to USB 2.0, it has a better data transfer rate and can supply more power to the device connected. Therefore, you should check if your computer has a USB 3.0 port, if it does, use it for external Hard Drives.
2] Manage your Drivers
The issue can be because of corrupted, outdated, or buggy Hard drive drivers. So, you can roll back, update, or reinstall the driver in question and resolve the issue.
3] Rescan Disks
Let the process complete as it may take some time and check if the issue persists.
4] Take Ownership of the Drive
Usually, you will have ownership of the connected drive, but usually, you won’t even see the error message. Therefore, we need to see how to take ownership of the drive in question here.
IMPORTANT: It is fine to take ownership of a Data drive, but you should never take ownership of your System Drive where Windows is installed. In such a case, it is better to take ownership of the folder only.
Now, try doing whatever you were doing before seeing the error and see if it works.
5] Check your Hard Drive health
A faulty Hard Drive can cause the error message to appear. Hence, you need to check if your Hard Drive is the one causing the trouble. The best thing to do would be to just plug it into another computer and try doing the same thing there. If the error appears again, then the chances are you need to replace it.
If you have a USB cable that connects the HDD/SDD to a computer, you should try replacing it and notice if that fixes the issue. Sometimes, faulty cables can cause the error as well.

Драйвера устройств обычно скрываются в менеджере устройств как только устройство отключится или подаст команду на скрытие (несмотря на то, что они по прежнему установлены в системе). Очень часто «одноименные» драйвера конфликтуют из-за несоответствия версий и пр.
Методика очистки списка не используемых устройств: (Уже многими опробовано и даёт хорошие результаты когда ничего уже не помогает «увидеть» работоспособное «устройство».
0. Отключите от компьютера все внешние USB-устройства.
1. Создайте переменную окружения с именем DEVMGR_SHOW_NONPRESENT_DEVICES со значением равным 1.
Для этого: 1.1. Щелкните правой кнопкой на значке «Мой компьютер» (My Computer) и выберите пункт «Свойства» (Properties).
1.2. В открывшемся диалоговом окне перейдите к вкладке «Дополнительно» (Advanced) и нажмите на кнопку «Переменные среды» (Environment Variables).
1.3. На расположенной в верхней части диалогового окна панели «Переменные среды» нажмите на кнопку «Создать» (New).
1.4. В поле «Имя переменной» наберите (лучше скопируйте отсюда) DEVMGR_SHOW_NONPRESENT_DEVICES, а в поле «Значение переменной» введите 1.
1.5. Два раза подряд нажмите на кнопку «OK».)
Созданная переменная окружения разрешит менеджеру устройств показывать все установленные в системе драйвера устройств (как скрытых, так и всех, когда-либо подключавшихся к компьютеру).
2. Вызовите менеджер/диспетчер устройств:
3. Щелкните правой кнопкой на значке «Мой компьютер» (My Computer), выберите пункт «Свойства» (Properties) и перейдите к вкладке «Оборудование» (Manage).
4. Нажмите на кнопку «Диспетчер устройств» (Device Manager), раскройте меню «Вид» (View) и выберите команду «Показать скрытые устройства» (Show Hidden Devices).
5.4 Раздел «Контроллеры универсальной последовательной шины USB»: Здесь можно удалить все СКРЫТЫЕ (серенькие) устройства: «Ваше устройство» Device USB Driver, Запоминающее устройство для USB, Неизвестное устройство и другие.
5.5 Перезагрузите компьютер.
6. После всех этих удалений попробуйте заново подключить «ваше устройство». Он должен обнаружиться как новое устройство и Windows установит к нему драйвера или вы их установите сами ( на некоторых устройствах нужно устанавливать драйвера без подключения по USB, т.е. подключать после установки драйвера).
6.1 Перезагрузите компьютер.
Обычно такая процедура устраняет все проблемы в конфликтных драйверах «вашего устройства».
