Eject USB Flash Drive From Windows Command Line

Microsoft does not provide ways to eject USB flash drives with a single click, or automatically. Universal Serial Bus (USB) is the #1 method for expanding storage in Windows, yet Microsoft makes ejecting a storage device such a manual process! Frustrating to many, like you, because you are here. {wink}

Today we cover how to eject a USB flash drive in Windows in the command prompt. In addition, this article also provides a software way to eject a USB flash drive with the single click of a button. Yes, that is right, a single click!

Let us start by covering how to eject a USB drive using the command prompt.

Like mentioned above, Microsoft does not make this easy. The user must get into DiskPart, List the volumes (drives) connected, select the specific volume (drive) then eject by typing “release.”

The above commands may be performed via the command prompt, but honestly it’s a pain in the a$$ because all the typing involved and manually selecting the device. This process needs to be automated. {hint}

If you are reading this article you want to make things quick, easy and simple.

Nexcopy solved this problem with a free utility that doesn’t require installation, doesn’t require Admin rights, and doesn’t require you to select the drive. The tool is ultra-quick and ultra-easy. In addition, anyone can bundle the free exe file into their own software to automate the process.

The free software tool is called USB Eject Button

Here is the download link to eject USB flash drives from Windows command prompt

Below is the command prompt using a single word to eject a USB flash drive. The command is “release”

However, what if multiple USB flash drives are connected? Is it still just as easy to eject all the USB flash drives? The answer is yes. The USB Eject Button tool works by automatically selecting the last USB flash drive connected to be the first USB flash drive ejected.

Below is an example. We connected “Drive One” first, then “Drive Two” and finally “Drive Three”

Make a USB Flash Drive Appear as CD-ROM Drive – Hardware Solution


Lake Forest, CA – July 19, 2021 – Nexcopy Inc., a leading manufacturer of advanced flash memory solutions, introduces Disc License CD-ROM flash drives. This technology will make a USB flash drive appear as a CD-ROM drive in any host.

Make a USB Flash Drive Appear as CD-ROM Drive

Disc License flash drives provide a migration path for those who depend on optical media such as CD and DVD but can no longer offer the product because optical drives are nearly gone in standard laptop and desktop computers.

The Disc License product is a USB flash drive which appears as a CD-ROM device when connected to a host computer. This is a hardware solution which emulates a CD-ROM and is read-only (write protected) meaning data on the drive cannot be changed, manipulated, deleted or formatted off the drive. This is the best method to create a USB CD-ROM flash drive.

“Think of a Disc License drive as a blank CD or DVD,” states Greg Morris, President of Nexcopy. “The blank CD-ROM will have the capacity of whatever the Gigabyte capacity the customer orders. Simply point our software to any ISO file and the data will be written with the resultant drive being that of a CD-ROM.”

Morris continues, “What is so elegant about this solution is being able to re-write an ISO file to the device at any time. In an abstract sense, you could say this is a CD-RW solution, but in the shape of a USB flash drive.”

With the optical drive quickly going away, users are seeking alternate solutions to provide data as a CD-ROM device. There are many advantages to CD-ROM discs which have served the technology sector for many years. The auto-run function of CD-ROM is key to many software suppliers who depend on a quick and simple installation process. The CD is a read-only device by definition so the added benefit of a virus or malware not jumping onto the flash drive is an inherent benefit.

The Nexcopy Disc License CD-ROM USB flash drive has the following features:

Features: Make a USB Flash Drive Appear as CD-ROM Drive

  • Default state of drive is read-only, a.k.a write protected
  • Use any ISO file to create a CD-ROM USB flash drive
  • Includes bootable ISO files
  • Make a USB Flash Drive Appear as CD-ROM Drive
  • Free data-load software to produce CD-ROMs
  • Re-write a new ISO file to the drive at any time
  • This is a hardware solution so cannot be hacked or manipulated
  • Available in USB 2.0 and 3.0 technology and ranging from 2GB through 128GB capacities

Free USB Speed Test Utility

Did you know Windows 10 has a speed test feature you can easily run from the CMD prompt?

This feature is what many USB flash drive speed test applications call upon during their operation. Rather than download some software utility off the internet, which only god knows what virus could be lurking inside, just use the Windows tool.

In addition to avoiding the possibility of a virus from a internet download, this tool is a standardized feature everyone has. In the event you are having performance issues you are trying to report to a flash drive manufacturer, this tool gives you both the same code to perform USB flash drive speed tests without having different applications giving varied results.

Every flash drive manufacturer claims a particular read and write speed of their flash drive and this is a great tool to verify what you purchased is what you received. It’s been said manufacturers will manipulate their computer environment to optimize the performance and use those optimized results as their marketing material. This could be true when a manufacturer is trying to determine the maximum performance, so let’s take a look now at benchmarking a standard environment.

The read and write speed of a flash drive will depend on the USB port one is using during the test. You will see a performance difference between a USB 2.0 and USB 3.0 device that is connected to a USB 2.0 or USB 3.0 socket on your computer. So take note about what you are doing!

After you’ve connected the USB drive to your USB port, take note of which technology they are, and be sure no data is on your drive. Although this Windows utility did not remove our data during testing, one can never be too sure.

In Windows type CMD into the search field.

Please be sure to use the Ctrl + Shift keys when you click the Enter key. This will run the command prompt at the Administrator level. You want to run this at the Admin level because if you don’t, a separate window will pop up during the testing process and immediately disappear with the process is done… taking the speed test results with it!

Once you’ve opened the command prompt at the Admin level, type the following:

winsat disk -drive d (where d is drive letter)

Windows will perform it’s task and should take about one minute to complete. The results will be printed out in the console window once everything is complete. Take note from our example below. This is a 64GB drive which we connected to both a USB 2.0 socket and a USB 3.0 socket. You can see the performance difference.

The information you want are:

  • > Disk Sequential 64.0 Read
  • > Disk Sequential 64.0 Write

Nice feature, right? Free and immediately available.

For those who don’t want to go this far, you could always take a large file, say 100MBs or larger and drag-and-drop this to your USB flash drive for speed testing. Just look at the copy process window and you’ll get a fairly good idea of device speed.

It’s important to remember flash drive media does not copy at sustained transfer speeds. The speed process does move around during the copy process; however, the read process is more stable and should happen at a more sustained transfer speed. We’ve seen drives drop down to 1MB/second for a short bit, before jumping back up to 30+MB/second write speed.

The new iPad OS Supports Flash Drives and SD/microSD Cards

Today Apple announced the new iPadOS will support USB thumb drives. The iPad has long been toughted a workers tablet from Apple, but the relaity is their iPad didn’t provide much functionality. In addition, the devices have limited storage.

With today’s announcement the above argument could get a little muted.

Update: We learned the iPad will allow other storage devices such as external hard drives and SD or microSD cards (with USB adapters). The USB port will also allow for HID devices, such as a USB mouse and keyboard. We are not sure if the iPad will support Bluetooth mouse and keyboard, but we’ve got to assume, right!

There is no word about the connection. The connection could be one of three; an adapter, USB-C socket size or the classic USB type A socket size.

2TB Sony Memory Stick Pro

Wouldn’t it be nice…a 2 Terabyte Sony Memory Stick?  It just might replace my trusted 8GB flash drive I use obsessively.  Bummer it’s not a real product [yet].

2TB Memory Stick Pro

Sony put out a specification for this new Memory Stick Format Series for Extended High Capacity on the oss-formats.org website earlier today.  The new series uses the exFAT format to reach these higher capacities, but still offers up poor transfer speeds of 480Mbps [60MBs per second].  That translates into a data load of about 555,555 hours – WOW – is my math wrong? The Memory Stick XC format series should deliver a maximum capacity of 2TB, 60 times larger than the company’s Memory Stick Pro, currently at 32GB. What’s even more interesting is that, at least on paper, the XC series will have the same form factors as Sony’s current PRO series. Continue Reading 41 Comments
