What replaces write protect switch on USB flash drive?

physical write protect switch, USB

The concept of a write protect switch on a USB flash drive is to make it read only (locked). When the device is locked content on the drive cannot be changed, altered, manipulated, formatted or deleted off the drive. What GetUSB.info never understood is the value of a physical write protect switch.

Sure a USB write protect switch helps the honest people stay honest, but that approach isn’t very secure and certainly doesn’t apply for all situations.

So what replaces a write protect switch for a USB flash drive?

How about a programmatic way to add or remove the write protection to a flash drive?

Better yet, how about assigning a password to the programmatic way of adding or removing the write protection?

We can relax because the Lock License drives address both of these issues.

The Lock License drive is a hardware based ( at the chip level ) write protection solution and through a specific vendor software command the write protection can be removed to make the USB stick writable.

The write protection is configured on the USB controller of the flash drive. This means the write protection is done at the device level and will follow the USB stick. The result is a Lock License drive which is truly read-only when connected to anything… such as a Windows computer, Mac computer, Linux box, Smart TV, car stereo, anything!

The Lock License drive comes with a software method to unlock the drive and make it writable. This special software requires a password to be assigned to the unlocking. The password is required because the manufacturer, Nexcopy, didn’t want a universal way to unlock the drive.

Kanguru manufactures a USB flash drive with a physical write protect switch. The write protection itself is as secure as the Lock License solution, the difference is a Lock License drive adds one additional layer of security. The additional layer of security, the password requirement, is an important step for ensuring the device is as secure as possible.

Another interesting fact about the Lock License drive is the default state of the USB stick being read-only, or write protected. This means it is impossible for a user to accidently leave the Lock License drive unlocked.

The “locking” or write protection is done when power is cut from the device. Even if a user forgets to lock the drive, the locking happens automatically when the USB is disconnected from the computer.

It is worth noting there is no universal way to write protect any flash drive, this is why you cannot buy some software solution to do the feature. Write protection is a hardware based solution, not software.

The Lock License drive is manufactured by Nexcopy Inc who is based out of Southern California. The product is available in both USB 2.0 and USB 3.0 technology and ranging in GB capacities from 2GB through 128GB.
