Why is my 2TB Pen Drive Unable to Copy Larger Files in Folders?

When dealing with a 2TB USB pen drive that does not seem to copy larger files efficiently, issues can arise due to several factors. This article will explore the common reasons behind such problems and provide practical solutions for efficient data transfer.

Understanding File System Limitations

The primary issue often stems from the file system on the USB drive. The most common file systems are FAT32, NTFS, and ExFAT. Each has its own limitations and advantages.

FAT32 is widely supported across different operating systems, but it has significant limitations. FAT32 is limited to a maximum drive size of 32GB and file sizes up to 4GB. This can be a major limitation when using a 2TB USB drive.

NTFS and ExFAT offer better suitability for larger files and drives. NTFS is compatible with Windows operating systems and offers better security features. ExFAT is a more versatile file system that is widely supported by various operating systems, including Windows, macOS, and Linux.

Common Issues and Solutions

One common issue is the size of the USB drive itself being misrepresented. Many counterfeit USB drives falsely report a capacity of 2TB, but in reality, they are much smaller. If you bought a USB drive for a price lower than its claimed capacity, it is highly likely to be a fake.

Another issue could be the operating system's inability to cope with large files in a single copy operation. If your PC cannot handle more than 26 or 27GB in one go, you may need to break the copy operation into smaller segments. This method can ensure the data transfer process is more manageable and less prone to errors.

Reformatting for Better Compatibility

To address file size limitations and ensure compatibility across various devices, you can reformat the USB drive. Here are some file systems that can be used:

ExFAT: This is a modern file system that is backward compatible with older systems like FAT32 but can support larger files and larger drives. It is supported by all major operating systems, ensuring wide compatibility.

NTFS: Ideal for compatibility with Windows-based systems, where both reading and writing are fully supported. macOS supports reading but not writing to NTFS partitions.

EXT4 and BTRFS: These are file systems mostly used in Linux environments. While they are not supported natively by Windows, they offer robust features and are highly reliable.

Choosing the Right File System

Your choice of file system should consider the devices and operating systems you intend to use the USB drive with.

For broad cross-platform support, ExFAT is the best choice since it is supported by Windows, macOS, and Linux. For Windows-only use, NTFS is suitable as it ensures full compatibility and security. For Linux-only use, EXT4 or BTRFS would be appropriate, although they are not suitable for Windows environments.

If your USB drive is plagued by firmware issues or is a counterfeit, it is important to purchase a genuine and reliable one from a reputable manufacturer. This ensures the longevity and reliability of your storage device.

Additional Tips for Efficient Data Transfer

Several additional tips can help streamline your data transfer process:

Ensure that the USB port and the drive are clean and free of dust or debris. Update your operating system and drivers to the latest versions, as these updates can improve compatibility and performance. Use reliable and fast copying software tools to manage your data transfer process. Store and organize your files in smaller subfolders to facilitate easier data management and quicker transfer times.

By understanding the limitations of different file systems and taking the necessary steps to address them, you can ensure efficient and reliable data transfer on your 2TB USB pen drive.
