Windows 10 Drivers | DriverFinder - We Make Drivers Work for You

In modern computing, encryption and decryption play a crucial role in protecting sensitive information from unauthorized access. These processes ensure that data remains secure when stored or transmitted. One of the key hardware components responsible for handling encryption and decryption tasks in a computer is the PCI encryption/decryption controller. To function correctly, this controller requires specific drivers, which allow Windows 10 to communicate with the hardware.

This article provides information about PCI encryption/decryption controllers, their role in a PC, the drivers required for their operation, where to obtain these drivers, and how to install them.

What is Encryption and Decryption?

Encryption is the process of converting readable data (plaintext) into an unreadable format (ciphertext) to prevent unauthorized access. Decryption is the reverse process, where the ciphertext is converted back into plaintext so it can be read and used by authorized users.

Encryption ensures security in various scenarios, including:

Protecting sensitive files stored on a computer.
Securing internet communications such as emails, website traffic, and VPN connections.
Encrypting data stored on external drives and USB devices.

The decryption process is essential to retrieve and use encrypted data, ensuring that only authorized individuals or systems can access the original information.

BitLocker is an example of Windows software that uses encryption and decryption.

Devices in a PC That Handle Encryption and Decryption

A typical PC or laptop includes several hardware components that perform encryption and decryption tasks:

TPM (Trusted Platform Module): A dedicated chip that handles cryptographic operations, ensuring the security of encryption keys and passwords. See TPM drivers.
CPU (Central Processing Unit): Modern processors include built-in encryption instructions, such as Intel AES-NI and AMD Secure Processor, which speed up encryption tasks.
GPU (Graphics Processing Unit): Some graphics cards support encryption acceleration for video streaming and secure processing.
SSD (Solid State Drive) with Hardware Encryption: Some SSDs come with built-in encryption capabilities to secure stored data.
PCI Encryption/Decryption Controller: A specialized hardware component on the motherboard responsible for handling encryption and decryption operations at the system level.

As mentioned earlier, making sure that the drive is connected on a supported USB port (3.0 or higher) will ensure making transfer speeds. If the drive is slow despite being connected on the right type of port, other causes make result in the drive not performing as expected, or freezing altogether.

Check for Errors: Use the chkdsk utility to scan and repair the drive. Open a Command Prompt as an administrator and type “chkdsk X: /f” (replace “X” with the drive letter for the WD passport). Optional, run the utility wit the additional “/r” parameter to check for physical errors.

Disable USB Selective Suspend: Go to Control Panel -> Power Options -> Change plan settings -> Change advanced power settings -> USB settings. Disable USB selective suspend.

Data Not Accessible or Corrupted Files

If the disk is accessible, but (some of) the data on the disk is not accessible, this indicates a more serious issue. Very often, this means that there is physical damage to the drive.

If the data store on the drive is critical to you, you can try and recover the data using data recovery software. Use software like WD’s Data Lifeguard Diagnostic Tool or third-party recovery tools to attempt to recover lost data. Unfortunately WD discontinued support for their Lifeguard Diagnostic Tool, so you’ll need to find a copy of that from an alternate source. But there are good third-party solutions available with free evaluation options. That will give you an idea of potential recovery.

If the data on the drive cannot be recovered, or is not that critical to you, you can reformat the drive. Right-click the drive in File Explorer and select Format.

Conclusion

WD Passport drives offer a versatile and reliable way to expand your storage, secure data, and keep backups. Ensuring your device drivers are up to date is crucial for smooth operation with Windows 10.
