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 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.”

We then ran the command to eject the USB flash drives. The tool ejected; Drive Three (F), then Drive Two (E) and last, Drive One (D).

Again, Nexcopy provides this tool for free and doesn’t require installation, doesn’t require Admin rights, and doesn’t require a User to select a drive. The tool is free to bundle with other applications if one chooses.

The USBEjectButton.exe file used for the command prompt, has a very slick graphical user interface. Simply download the zip file and extract it to any location. Then make a shortcut to the exe file and place the shortcut on your desktop, or better yet, the taskbar in Windows.

The USB Eject Button tool is designed so when a User clicks the shortcut icon, that click triggers the ejection process and ejects the USB flash drive. Simple – Slick – Instant

There is even a Windows happy sound so the User knows it happened.

With the shortcut in the dashboard of Windows it is now possible to eject a USB flash drive from Windows with the single click of a button! Brilliant.

Here is a video showing the process of ejecting a USB flash drive with the single click of a button, along with ejecting the USB flash drive in the command window.

So what does this USB Eject Button do if there is no USB flash drive connected? If there is no flash drive connected and the user clicks the shortcut link, then a Nexcopy website page appears in your default browser.

The website page provides information about different Nexcopy USB products. Given Nexcopy put in the work to make such a nice, simple and free utility, this is not that intrusive. The webpage lists the four different types of flash drives Nexcopy offers:

• Copy Secure drives which are USB flash drives that provide copy protection to MP4 video files, MP3 audio files, PDF files, HTML pages, Text files, image files and more.
• Lock License drive; a technology having the default state of the USB stick as write protected (locked) and the user can programmatically unlock the drive.
• Disc License drives which create true USB CD-ROM flash drives from an ISO file. This is not a software solution, but a hardware solution.
• USB encryption flash drives which protect all content with a password and strong AES encryption technology.

Silicon Motion’s decade-long growth drives a 580% return for investors.

Silicon Motion Technology Corporation (NASDAQ: SIMO), founded in 1995, has become a leading developer of microcontroller ICs for NAND flash storage devices. The company also designs and markets high-performance, low-power semiconductor solutions for OEMs. Among its customers is Nexcopy Incorporated, a Southern California technology company specializing in flash memory storage products.

Today, Silicon Motion holds more than 1,500 patents, with over 1,300 still pending final approval. Its annual revenue is around $540 million, underscoring the company’s strong position in the semiconductor and storage controller markets.

From an investor’s perspective, the company’s performance has been even more striking. A $1,000 investment made in August 2011 would be worth approximately $6,832 as of August 23, 2021—representing a gain of 583.19% over the ten-year period. This return accounts for price appreciation but excludes dividends, according to NASDAQ’s analysis.

Since August 2021: where’s SIMO now?

Back in late August 2021, Silicon Motion (SIMO) was trading in the low-$70s. Fast-forward to today and the tape tells a different story: as of September 22, 2025 the stock closed around $95, brushing an all-time closing high and marking a solid climb despite a very bumpy road in between.

What changed? The company kept shipping controllers—lots of them—and kept widening the moat. In 2024, SMI rolled out its SM2322, a single-chip USB 3.2 Gen2x2 portable SSD controller that hits 20 Gbps and scales to roomy 8 TB QLC builds. That’s catnip for phone-to-console workflows and the “throw it in the bag” creative set. Momentum like that doesn’t show up in a quarter; it shows up in a trend.

Then there’s the long game. At industry events in 2025, SMI teased a PCIe 6.0 client SSD controller (codename Neptune) with projected 25+ GB/s reads and 3.5 M IOPS, signaling where the ball is headed—even if broad client adoption waits until the 2030 window. It’s classic SMI: ship today, signal tomorrow, keep the design-win pipeline full.

Of course, it wasn’t a straight line up. The MaxLinear deal drama peaked and cracked (termination in 2023), sent the shares wobbling, and moved the fight to arbitration and courtrooms. Through it all, the company kept printing controllers, paying a dividend (announced $2.00/ADS for 2024), and talking product roadmaps—slow, steady, stubborn. That posture matters to multiples.

So where do we land versus that August 2021 snapshot? Call it this: SIMO today trades notably higher than those early-’21 levels, near record territory, after digesting a failed merger and a memory cycle. That resilience, paired with portable-SSD wins and next-gen PCIe signals, explains why the stock now lives closer to the mid-$90s than the low-$70s. In other words—Morris’ rule of thumb—execution begets altitude.

Nexcopy introduces Disc License flash drives that emulate a CD-ROM device.

Lake Forest, CA – July 19, 2021 – Nexcopy Inc., a leading manufacturer of advanced flash memory solutions, has announced the release of its Disc License CD-ROM flash drives. These devices provide a hardware-based way to make a USB flash drive appear as a CD-ROM when connected to any host computer.

Why Disc License?

With optical drives disappearing from modern laptops and desktops, organizations that relied on CD or DVD media need alternatives. The Disc License drive bridges that gap. It appears to the system as a CD-ROM and is permanently read-only, ensuring that files cannot be altered, deleted, or reformatted. This makes it an effective method to create a USB CD-ROM flash drive that retains the benefits of optical media.

Greg Morris, President of Nexcopy, explains: “Think of Disc License as a blank CD. The drive capacity matches the GB size ordered by the customer. Point our software at any ISO file and the drive becomes a CD-ROM.” He adds, “What makes it elegant is the ability to re-write ISO files at any time. In practice, it’s like a CD-RW—but in the form of a USB stick.”

Key Benefits

Optical discs have long been trusted for software distribution thanks to auto-run functionality and read-only protection. Disc License preserves those advantages while moving away from fragile optical media. Because the device is hardware write-protected, it cannot be infected with malware or tampered with once data is loaded.

Features

• Default state is read-only (hardware write-protected)
• Burn any ISO file to create a CD-ROM USB flash drive
• Supports bootable ISO files
• Free Drive Wizard software for ISO burning
• Re-write with new ISO files anytime
• Hardware solution—cannot be hacked by software
• Available in USB 2.0 and USB 3.0, 2GB to 128GB

Industry Response

Stan McCrosky, head of Sales, highlights the demand: “After 15 years in the CD/DVD duplication industry, we’ve seen companies struggling to repurpose large ISO libraries. The Disc License drive solves that immediately—no conversion needed. Customers can use their ISO files as-is, and the response so far has been overwhelming.”

Implementation

Using the drive is straightforward:

• Connect the USB drive to a Windows computer
• Open the Drive Wizard software
• Select an ISO file
• Click “Burn” to write the ISO

To re-write, follow the same process—Drive Wizard will overwrite the old image with the new ISO.

Options and Availability

Nexcopy offers the Disc License in six body styles with customizable colors and branding, including Oxford (swivel), Newport, Lexington, Augusta, Huntington, and Geneva. The Oxford swivel drive is stocked for same-day printing and shipping, available in USB 2.0 (2GB, 4GB) and USB 3.0 (8GB–128GB). Custom branding is available through Nexcopy’s Logo-EZ printer.

The Drive Wizard software is available from Nexcopy’s support page and requires licensed Nexcopy drives to function.

News Review: Nexcopy Launches USB-C Duplicator For Mass USB-C Duplication

Nexcopy announced a new USB-C Duplicator, available for immediate purchase. The USB-C200PC is a 20-target, PC-based system designed for high-volume Type-C deployments and comes bundled with Nexcopy’s feature-rich Drive Manager software.

Via the EIN Presswire service, Nexcopy noted rising demand driven by Apple’s adoption of USB-C on Macs and the broader shift to USB-C across IoT products. As device makers migrate to Type-C, duplication workflows are following suit.

Being PC-based doesn’t mean sacrificing speed or capability. The USB-C200PC leverages modern SuperSpeed protocols (commonly referred to as USB 3.1/3.2) and writes at the connected device’s maximum sustained rate. While USB 3.1 Gen 2 advertises up to 10 Gbps theoretical throughput, real-world duplication performance depends on the media and workload.

The system ships with Drive Manager, Nexcopy’s control software known for granular job control, verification, logging, and advanced media functions.

Highlighted Features of the USB-C Duplicator

• Six copy modes to match source/target workflows
• Binary device copy supporting all formats (HFS, ext2/3/4, proprietary, etc.)
• Unique data streaming to each USB-C socket (serialization, per-drive payloads)
• Binary verification for integrity assurance
• Erase and DoD Erase options for disk sanitization
• Data collection to extract files from connected USB-C devices
• Intuitive, informative Drive Manager UI with logging
• Upgradeable to PRO Series for controller-level write protection (read-only)
• Upgradeable to PRO Series for partitioning and advanced media control

The unique data streaming mode is a standout for publishers and on-demand fulfillment: it allows static content plus per-device files (keys, licenses, IDs) to be injected in a single run.

Nexcopy’s PRO Series capabilities—such as USB read-only (write protection), controller-level partitioning, and serial-number control—are also available as upgrades for the USB-C200PC platform.

Why USB-C Matters (Context)

Understanding why some drives mount as UDISK instead of USB—and what that really means for reliability.

With so many gadgets and storage devices in circulation, it’s worth stepping back to cover some hardware fundamentals. One example is the difference between a standard USB flash drive and something your system may identify as a UDISK. While both plug into a USB port, the technology inside is not the same.

USB Thief Malware Highlights Risks of Portable Media

Data security across the internet is already one of the most volatile and fast-changing fields. Bug exploits, malicious code, and countless data-stealing programs have pushed some organizations to remove sensitive systems from the web entirely. But a new hardware-level threat shows that even isolated networks are not immune to attack.

A recently identified malware sample called USB Thief was uncovered by researchers at the ESET security firm. Unlike traditional malware, USB Thief is completely USB-based. It spreads only when infected flash drives are inserted into computers, meaning no internet connection is required for compromise.

This Trojan is especially dangerous for air-gapped systems—networks intentionally kept offline to minimize exposure. That category includes financial exchanges, military installations, and industrial control systems. According to ESET, the malware’s most troubling feature is its ability to evade detection and resist reverse engineering. The firm has not disclosed the exact path of discovery, but the details show a high degree of sophistication.

USB Thief executes by attaching itself as a plugin or dynamically linked library (.dll) into the command chain of common USB applications. Each time the application launches, the malware runs invisibly in the background. It can steal documents, images, registry trees, and other data—all while leaving no footprint on the host machine since it resides exclusively on the USB device itself.

The most practical defense for organizations handling secure content is to use encrypted and write-protected drives. Write protection at the hardware level prevents any modification of trusted content and blocks the insertion of malicious libraries or executables. This approach is especially valuable for institutions distributing data across large user groups while maintaining control over integrity.

Nexcopy offers hardware-based copy-protected and write-protected USB drives, already deployed by global aircraft manufacturers, energy companies, and even emergency response training facilities. These tools ensure sensitive content can be distributed safely, while duplication hardware such as USB duplicators streamlines secure media distribution at scale.
