Where is the write protection switch on a USB flash drive?
Write protection switch. Some USB flash drives have a write-protection switch on the side or bottom. This mechanism is useful for keeping the contents of your drive safe from malware when you need to view them on a public computer. If your device has this switch, move it to the “Lock” position.

Why do I have write protection on my sd card?
Write protection on USB flash drives or SD cards is a handy function aiming to prevent accidental file deletion and block suspicious files like virus and un-authorized sources. External data storage devices are very common devices and they are widely used these days, as they are portable and users can take them anywhere they want.
Is it possible to remove write protection from AP firmware?
By design, this write protection cannot be removed without physical access to the device. AP firmware (also known as “SOC firmware”, “host firmware”, “main firmware” or even “BIOS”) typically resides on a SPI ROM.
Why do I need write protection on my computer?
The write-protection switch is useful for keeping the contents of your drive safe from malware when you need to view them on a public computer. If your device has this switch, move it to the “Lock” position. This action effectively sets all files, and the device itself, to read-only mode. Using DiskPart to change read-only settings

How does an input clipping diode protect the input?
Figure 13: Reading high voltage inputs. The input clipping diode to ground is to protect from less than zero volt spikes. The input clipping diode to the positive bus is removed in favor of the zener diode after the current limiting resistor. This provides a known voltage for the input pin and reduces the amount of current shunted to the power bus.
What’s the best protection for a digital input?
For most digital inputs, a good value is between 100 Ω and 10 kΩ. For our system, a value of 1 kΩ is used. Figure 6: Current limit protection for an input. This type of protection works well for short wire connection lengths and enclosed wire runs (little chance of EMI, etc.).
