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 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

USB 3.0 Trouble with Intel Haswell Processor

Intel has reported a problem between the Haswell processor, the next-generation microprocessor that uses 8-series cor-logic sets.

Intel says when a PC system with Core i-series Haswell inside wakes from S3 sleep mode, it experiences issues with devices connected through USB 3.0. Intel defines the issue only as a nuisance for end users, but who will be the real judge of that?

Clean Windows Registry of USB Drives

Here is a great tool for cleaning Windows Registry of USB drive entries. The program runs in the Windows console and removes all devices that are not currently connected.

To clean up the Windows registry of a USB flash drive, or other USB devices can make your system boot faster and run faster.

For example, each time you connect a USB printer to a different USB port on your PC there are registry entries made which associate the device with the drivers. Windows is trying to be smart and log this information so the next time you connect the device, Windows will know exactly what to do. Meaning when you connect the printer a second time, you don’t see the balloon from Windows saying “Installing Brother driver” or something, it’s just connected and ready to go.

But, for example, lets say you connect your Nikon camera to your PC and you use a different USB port each time, now you have a bunch of registry entries that can make your PC boot slower, run slower or possible give you trouble with that external device.

With all this said, if you are having trouble with a USB drive, or a USB camera, printer or scanner, the first thing you’ll probably want to do is run this Windows registry cleaner utility. Good chance it will solve your problems.

Flash Memory Puts Mars Curiosity into Safe Mode


As with any good project, there should always be a back up plan.  The Curiosity for Mars is no different.  The system has a B-Side computer in the event the A-Side computer went down…well guess what, it went down.

There is a theory that cosmic rays affected some of the flash memory on Curiosity causing the A-Side computer to shut down and reboot into Safe Mode.

JPL is currently backup up the A-Side data to the B-Side computer and should reboot by weeks end.  Configuration and data transfer can take a while, then of course the verification process of everything done right.

JPL states:

“The hardware that we fly is radiation tolerant, but there’s a limit to how hardened it can be, you can still get high-energy particles that can cause the memory to be corrupted. It certainly is a possibility and that’s what we’re looking into.”
