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.
How you make a working USB stick write protected is sending a
Can I connect a USB Type C cable to an older USB 2.0 port?
No you cannot.
The USB type C socket is a backward compatible technology with respect to the protocol but it is not backward compatible in the physical connection. Meaning, the sockets wont fit, but with an adapter you will have no problem charge devices or trasnfering data.
The USB-C connection was design for several reasons. Of course a new specification will always be developed to increase data transfer rates or introduce new features, such as increased power across the buss to charge or power connected devices. The main reason for USB-C connectors is size. With USB being the world’s most popular technology for peripheral devices, the Implementers Forum (with members such as Intel, Acer, AData, SanDisk, Lexar, Micron and many others) they wanted to insure the USB specification continued to be the #1 method for connecting the ever decreasing size of digital devices.
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:
Infinite USB is a concept which dates back five years. The concept is brilliantly simple. The USB cable design allows multiple devices to be charge from an extending USB plug, and at the same time, allow data transfer through that one original USB port.
Today, Infinite USB has released a new version for the Mac computer. One which supports Apple’s Type C connector. This is a really smart move on Infinite USB’s part because the Mac computer only has one USB port. So additional sockets is very important.
Like the original design from years back, the connection is simple and straight forward.
Using the original USB port of the computer, the Infinite USB creates a pass through, or extended USB port. They do this so that once the Infinite USB cable is connected, you still have access to the data transfer ability of that original Mac USB port. However, Infinite USB was ultra-clever and created a design to steam off some power form the USB buss so you can charge additional devices.
The USB connector builds upon this concept with module cables and connectors so you may continue to high-jack power off the original USB socket, while still having the original USB port with data transfer capabilities.
To be perfectly clear, the Infinite USB will only transfer data to one USB device… it will not transfer data to all the devices connected. It is important to understand the Infinity USB concepts is a creative charging station, not a USB hub.
The product can be found on Kickstarter for $20. There is only one day left at the time of this writing, after that you can order product through the company website.
Good luck guys, we love the product!
Sometimes you will connect a USB to the PC and get an error message saying the drive has a GPT Protective Partition and you cannot format the drive. Here is the fix to resolve the issue:
First, what is a GPT USB stick? The GUID Partition Table (GPT) is the successor to the Master Boot Record. The MBR was created by IBM back in the early 90s. The problem with MBR is the limitation to partition table sizes which is 2 Terabytes.
Since there are no 2T USB flash drives (at the time of this post), there is no need to use GPT as your partition table.
Removing the GPT Protected Partition can be accomplished through the Windows Diskpart program.
- Determine the Disk Number for the USB GPT-protected drive. To do this, perform the following:
- Right-click on (My) Computer.
- Choose Manage.
- Select Disk Management (listed under Storage).
- Look for the drive that is identified as GPT and note the Disk number (such as Disk 1).
Format USB GPT Protected Partition
- Now, open a Command Window. From the command prompt, type diskpart and press Enter.
- The diskpart prompt will open.
- From the diskpart prompt, type list disk and press Enter. A list of disks will appear in a text format. You will return to the diskpart prompt.
- From the diskpart prompt, type select disk disknumber (in this example from the screen shot above, you would type select disk 1)and press Enter. A message appears saying that the disk is selected. You will return to the diskpart prompt.
- From the diskpart prompt, type clean and press Enter. At this point the drive’s partition and signature a removed. You will return to the diskpart prompt.
- From the diskpart prompt, type exit and press Enter. Type exit once more to close the Command Window.
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 of 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
