The USB is Write Protected: Why?

USB write protected means the USB cannot be written to. But why?

There are really only two reasons why a USB stick is write protected.

#1 The USB is corrupted in some way and is no longer working properly. It’s actually very easy to destroy a USB stick and the most common way is sending multiple write threads to the device. So for example, you decide to copy a bunch of files form your computer to your USB stick. While that data transfer is going on, you give another request to write data to the flash drive. If the second request doesn’t write protect the USB, then try sending a third command, all at the same time of course, and this will certainly write protect the drive.

#2 The USB is write protected by design. Meaning the content owner (person who put data on the drive) made the stick read only. Read only is another way of saying write protected.

Nexcopy Introduces Write Protection for SD Cards

Nexcopy Inc., microSD Duplicator

Lake Forest, CA — July, 2015 — Nexcopy Inc., introduces a new software suite which supports data locking content to secure digital media. The software function supports both full size Secure Digital card media and microSD card media. The data locking feature will turn the SD card into a read only card so data cannot be deleted or formatted off the device.

Write protecting, or data locking content to flash memory is an important security feature. With the Nexcopy software and duplicator, data can be copied to the memory card and as a final step the device will be write protected at the controller level. Performing the data lock at the controller level blocks any third party from manipulating, hacking or tampering with the original content.

With the Nexcopy duplication software and hardware solution, a content owner has the following benefits:

How To: Make a USB Read Only

There are two ways to make a USB stick read only. One way is a universal solution and is 100% permanent, the other way is PC specific and a good deterrent. When we say 100% permanent, this means the USB stick is read only (write protected) on all computers, whether it be a Mac, PC, Linux, etc type computer, the USB is read only and the status cannot be changed. The other method flags a USB device to be read only in relationship to the PC it is connected to so that whenever that USB stick is connected to that computer, it makes the USB read only and blocks all write commands to the device.

Most times an IT manager or content owner wants the USB stick to be read only so the files cannot be deleted or formatted off the drive. Another reason for making a USB read only is for the original files to remain the same and blocks the ability for files to be changed or manipulated. Finally, it’s smart to have USBs read only so that virus’ don’t jump onto the drive and possibly spread to other computers.

Let us start with the less permanent way because it’s easier to do and doesn’t require any specific hardware. You will need a Windows7 machine or higher. The Windows7 machine will have DiskPart utility which allows us to perform all sorts of cool things to flash drives, like setting write protection.

  • Connect the USB to your Windows computer.
  • To begin, go to your Windows Start and in the Search Field type “cmd”

This will run your Command prompt.

  • Next, you will want to get to the C root of the Command prompt and if you are signed in as a user you can simply type cd\ this will get you back to the root of the C drive.
  • Type DISKPART
  • Type LIST DISK

Now you will need to find the USB stick connected to your PC. Most likely it’s DISK 1

USB Copy Protection by Nexcopy

Nexcopy has released a USB Copy Protection solution for those who need to share files, but without giving the “receiver” full ability to copy and re-distribute. The great thing about a USB flash drive is file sharing.  They are great for copy and saving and taking files on the road.  This same convenience factor also makes it very difficult to have Digital Rights Management as well.  With Nexcopy’s USB Copy Protection, it’s not difficult any longer! First, lets explain the difference between write protection and USB copy protection.  Some thing it’s the same, but it’s not. USB write protection [also called data lock] means the files cannot be deleted off the drive…it also means files cannot be added to the drive.  But you can still copy the files off the drive to your desktop or hard drive. USB copy protection provides the same functionality as write protection, but in addition, does not allow Continue Reading

How To: Read CID on SD card

How To Read CID on SD card

If you are looking to read the CID number of an SD card, or extract the CID off an SD card then you’ve find this article very helpful.  Some also call this “reading the PSN off the SD card” or reading the product serial number off the SD card.

Most phones and much of the software on phones will lock in to the CID number of a SD card.  The CID number is a unique card identifier number that is unique to the card itself.  The CID number is valuable because software developers and hardware developers can lock software to the unique number of the device thus eliminating the ability to pass along licensed software.

Reading the CID number from an SD card is not an easy task.  It requires specific access codes to the index table of the memory card, and unless you know how to use the SD chipset of your card reader, chances are you wont get the number…or least the correct and accurate number.

What is the CID number of an SD card?

The CID register is 16 bytes long and contains a unique card identification number. It is programmed during card manufacturing and cannot be changed by SD Card hosts.  The CID number is a compilation of information about the card, such as manufacturer, date manufactured, checksum total, GB size and more.  Below is a table outlining all the items which make up the SD CID number.

So with all this said, how do you read the CID number from an SD card?  As we’ve mentioned it isn’t easy and it’s [more or less] hardware based.  If you do enough searching on the internet you’ll find some home-brew code to read the CID numbers, but that’s only if you have the SD card or microSD card connected via an IDE bus to your host computer.  This isn’t easy for everyone.  There is clear evidence that using a USB to SD card reader will not get you the information you require, or at least accurate and correct information.  Meaning most times the CID number generated is actually the serial number of the card reader itself, not the CID number of a specific SD card.

In addition, what if you are required to read the CID number off SD media in bulk?  A single, one-at-a-time solution is not practical.

In my search to read the CID number from SD media, I cam across Nexcopy – a manufacturer of USB duplicator equipment and other flash memory equipment.  Several models they carry are SD duplicators and microSD duplicators.  With the secure digital duplicators part of their feature set includes reading CID numbers from SD media.  The equipment can ready 20 cards at a time, 40 cards at a time, or 60 cards at a time, depending on the model.  The duplicators will read the CID number and exported to a .csv file for import into other business functions.  This configuration makes it quick and easy to obtain the CID number.  Granted, the equipment is not designed for single use operation, but rather reading the CID of SD media in bulk quantity.  Here is a screenshot of Nexcopy’s software reading 20 CID numbers:

I didn’t contact Nexcopy Incorporated for pricing of the equipment, but doing a quick search for the equipment shows me a price of about $1k for the smallest 20 target system and $3k for the largest, 60 target system.

Review: Nexcopy 3.0 USB Duplicator

Review: Nexcopy 3.0 USB Duplicator

EverythingUSB posted a review of the Nexcopy 3.0 USB Duplicator with a bunch of “thumbs up” marks.  Lets take a closer look. As far as USB duplicators go, the Nexcopy SSUSB160PC is actually pretty stylish. Its form certainly flows from its function, but Nexcopy has made it to look in a German engineered car sort of way. Because of this form from function design, it is rather rectangular with flat boxy sides. However, Nexcopy did add in some flare where they could. For example, having the top slope downwards from back to front does give it a more aggressive styling. This dash of styling does makes it even more functional as sticking in the 16 flash drives into the 16 USB 3.0 ports on that self same top is actually easier when they are slightly offset in the vertical plane. It’s also a lot easier to check all 32 status lights for the 16 ports (red for bad, green for good). Where the Nexcopy USB 3.0 duplicator is a serious tool meant for serious work, there is no plastic fascia to be found anywhere. It is made from metal and metal only. Once again, Nexcopy did manage to sneak in some pizazz by having the front’s company logo be CnC’ed milled out. This allows air to be sucked in from the front (as well as the sides through copious amounts of air holes), flow over the internals and then be exhausted out the back of the case via the rear fan. This is a great example of form and function done properly. I first made an image file of my minted Windows 7 64-bit installation flash drive using the included basic software. (As a note, professional version or upgraded version of the software includes the ability to write protect drives, partition drives or set them as USB CD-ROM devices.) When that was completed, I setup a new batch job; pointed the software at the location of the newly created .IMG file on my hard drive; and then took Continue Reading
