Nexcopy first made waves back in 2009 with their USB400PC and USB600PC systems—PC-based USB duplicators offering 40 and 60 target ports. At the time, these systems broke ground by overcoming Windows’ drive letter limitations and offering a modular expansion path for high-volume USB duplication.

Fast-forward to 2025, Nexcopy continues to lead the field with a wide range of duplicators, now including USB 3.0 support, write protection, and advanced data handling features. Their modular system design allows users to scale from 20 ports to 60 ports by adding more hardware units to the same PC-based platform—ideal for Fortune 500 companies, schools, universities, and service bureaus.

The company also overcame technical challenges like Windows’ drive letter limit by bypassing the OS’s native mounting system. Instead, Nexcopy communicates directly with each USB controller, allowing the system to support dozens of devices simultaneously without exhausting the alphabet.

Current models include:

• USB160PC – A 16-port USB 3.0 duplicator offering File, Device, Image, Copy?Add, and Unique Data Streaming modes. Includes checksum verification, data collection, and bootable image support.
• USB160PRO – Adds advanced features such as hardware write protection, CD-ROM emulation, dual partitions, Copy Secure encryption, and descriptor-level customization.
• USB400PC / USB600PC – Still the largest standard PC-based duplicators on the market with 40 and 60 USB ports, updated with Nexcopy’s latest Drive Manager PRO software.

Nexcopy’s Data Collection feature remains a unique and valuable tool. It reverses the usual duplicator workflow by extracting data from each USB drive and saving it into uniquely labeled folders on the host PC. This is especially useful for teachers collecting student homework or companies retrieving field-collected data.

Remove Read Only USB – Remove CD-ROM USB Partitions

If you are like me, you’ve done a great bit of searching on the internet to remove Read Only USB partition or to remove CDROM USB partition, and unfortunately the information is very scarce and the information which is out there, isn’t very clear and direct.  The only utility we’ve found, is the one used to remove the U3 platform off a retail USB stick made by SanDisk, but chances are you are dealing with a different vendor or stick. In addition, the U3 platform was killed a long time ago by SanDisk because hackers kept using the auto-run function associated with CD-ROM discs to auto-run USB malware.

We found a company that can do this, and they do it in bulk, USBCopier.com is a USB duplication service company that specializes in fixing your problem, like removing a Read Only USB partition.  I’m not sure how they do it, but their services worked for us.

As you know, a simple format or delete attempt to the USB device simply doesn’t work…you get the “This disk is write protected” message. The flash drive is configured this way at the chip level, so it’s not a formatting problem. The chip inside the USB flash drive, called the controller, has a configuration setting so the device will appear as a CD-ROM device. Since the vendor commands are not available to access the USB controller chip, you cannot re-configure the device to work like a normal flash drive.

I spoke with USBCopier.com about the issue, and they can remove a USB partition off all types of drives, like USB sticks with Chipsbank controllers, Alcor, SMI, USBest, Innostor and many others.  They also said the partition type doesn’t matter, it can be either the Read Only or CDROM and they can remove it.  USBCopier also mentioned if they can remove the USB partition, then chances are, they can also recreate it.

The company was a life saver to us and I wanted to pass along the information.  It was much cheaper to pay the service fee to remove the USB partition than it was to re-buy all the USB sticks and start from scratch.
