Fix Can’t Copy Large Files from External Hard Drive Issue

It’s annoying when you can’t transfer big files from an external hard drive. Especially when it’s a backup issue with large files. The problem usually is you can’t copy files over 4GB to a drive formatted as FAT32. This is due to FAT32 limitations which cause error messages. They tell you the file is too large for the destination.

You might get an error when trying to copy a 4.32GB file to your SanDisk HDD. But don’t worry, there’s a way to fix this issue without losing any data. You can switch from FAT32 to NTFS. You have options like using Command Prompt or a third-party tool. A good option is AOMEI Partition Assistant Standard. It helps switch to NTFS smoothly and prevents data loss while fixing your hard drive issues.

Understanding the Issue: Why Can’t You Copy Large Files?

Trying to copy big files to an external hard drive can be frustrating. This often happens because of the drive’s file system limits. The FAT32 file system is common but only lets you transfer files up to 4GB. This size limit is too small for many current storage needs.

Common Error Messages

Have you seen messages like “The file is too large for the destination file system”? This error means your external hard drive probably uses FAT32. Created in 1995, FAT32 is still in use but can’t handle files over 4GB. This is why it’s not good for big files, such as DVD movies or large videos.

Compatibility Issues

System compatibility is important, too. Different file systems, like FAT32, NTFS, and exFat, work well with different devices. NTFS lets you use files up to 16 exbibytes (EiB). Yet, it might not work with old devices or non-Windows systems. exFAT, a newer system by Microsoft, works better for flash drives without big file size limits. It’s great for moving large files between various platforms.

Knowing these limits helps find solutions, like changing your drive’s file system. Choosing NTFS or exFAT can make a big difference. You’ll have easier and error-free transfers of large files.

Checking Your External Hard Drive’s File System

Before moving big files to your external drive, checking its file system is key. You can avoid errors in transferring files or issues with system compatibility by doing so. Simply access your drive properties via Windows Explorer to start.

How to Check File System

Follow this guide for help:

1. Use Windows Explorer to find your external drive.
2. Right-click the drive and choose Properties. This gives you important storage device information.
3. In the Properties window, go to the General tab. You’ll see if your drive’s file system is FAT32, NTFS, or exFAT.
4. If it’s FAT32 and you often deal with large files, switching to NTFS or exFAT is a good idea. These offer better storage and compatibility.

You can also use Disk Management in Windows for a thorough file system check. Here’s how:

• Hit Win + X and pick Disk Management from the menu that appears.
• Find your external drive in the Disk Management window and right-click it.
• Select Properties to see more about your drive, including its file system type.

Regular checks and reviews of your external drive’s properties keep you on top of disk space and file transfer optimization. This easy process ensures your drive works well, helping you steer clear of transfer troubles.

Convert FAT32 to NTFS Without Losing Data

Changing your FAT32 drive to NTFS lets you handle big files better and improves storage. You can use two main ways to do this: the Command Prompt or third-party software like AOMEI Partition Assistant.

Using Command Prompt

The Command Prompt method is simple for those who like using text commands. It changes your drive while keeping all data safe.

1. Open Command Prompt with administrative privileges.
2. Type convert X: /fs:ntfs (replace “X” with your drive letter) and press Enter.
3. Wait for the conversion to finish, which usually takes 3 to 8 minutes.

This way works for many devices, like USB drives, SD cards, and both internal and external hard drives. It’s flexible for different storage scenarios.

Using Third-Party Software

If you prefer something easier, AOMEI Partition Assistant is a great choice. This program makes converting your drive simple and offers extra benefits.

1. Download and install AOMEI Partition Assistant on your computer.
2. Launch the software and select the FAT32 drive you want to change.
3. Pick the “Convert FAT32 to NTFS” option and follow the directions.

AOMEI Partition Assistant works with different Windows versions, including Windows 11, 10, 8, 7, XP, and Vista, plus Windows Server. It converts your drive safely without losing data. It also supports SD cards, USB drives, and both external and internal hard drives.

Using these methods ensures you can switch from FAT32 to NTFS without losing data. This lets you enjoy NTFS’s benefits like managing large files and better security.

Reformatting External Hard Drive to NTFS or exFAT

Copying large files often means you need to reformat your external hard drive. You might pick NTFS for its performance or exFAT for working across different platforms. The Disk Management tool in Windows makes this easy.

Steps to Reformat with Disk Management

Windows 11 has a Disk Management utility that’s easy to use. It helps you switch to NTFS or exFAT, based on what you need. Follow this guide to start:

1. Open the Disk Management utility by right-clicking on the Start button and selecting “Disk Management”.
2. Locate your external hard drive from the list of volumes displayed.
3. Right-click on the drive and select “Format”.
4. In the popup window, choose either NTFS or exFAT from the “File system” dropdown menu.
5. Assign a volume label if desired. This will help in identifying the drive later.
6. Check the option “Perform a quick format” if you want a speedier reformatting process.
7. Click “OK” to initiate the reformatting process.

Backup Before Formatting

It’s essential to back up your data before you reformat. This keeps your information safe. Here’s the best way to do it:

• Data backup is crucial as reformatting will erase all existing data on the drive.
• Use a reliable backup tool or manually save important files to another storage device.
• Ensure the backup is complete and the data is accessible before starting the reformatting process.

Reformatting your external hard drive to NTFS or exFAT is great for managing your files better. It helps especially when you have lots of files, like over 80,000 photos. Plus, NTFS is great for Windows, and exFAT works well between Windows and macOS.

Fix Can’t Copy Large Files From External Hard Drive

Copying large files from an external hard drive can sometimes fail, even if it’s NTFS formatted. These problems can be due to poor connections or bad sectors on the drive. To ensure smooth file transfers, check your connections are secure and your drive is in good condition.

Connection Issues

Connection problems can make copying large files difficult. Make sure your cables and ports work well. Use different USB ports or cables, and skip USB hubs as they might slow things down. Also, using your operating system’s Disk Manager can solve these connection issues with your hard drive.

Device Health Check

Checking your device for problems is important to make sure it’s working right. Use Western Digital’s Data Lifeguard Diagnostics to see if your drive has bad sectors. Running these tests will show you any problems. Keeping your drive healthy is key to reliable performance and copying files without issues.

Conclusion

Understanding how to fix external drive problems often begins with knowing the drive’s file system limits. FAT32, a common file system, can’t handle files larger than 4GB. That’s why someone couldn’t move an 8.68 GB file to their external drive. Switching the drive to NTFS allows for moving bigger files.

Using tools like AOMEI Partition Assistant Standard helps manage files well. This free tool easily changes FAT32 to NTFS without losing data. You just right-click on the partition, choose to convert, confirm, and apply the changes. If keeping old data isn’t needed, you can also reformat to NTFS or exFAT for big file transfers.

Regular checks on your external drive are also important. This means looking for connection issues, checking device health, and making sure the drive works well. Checking hardware problems, reading kernel logs, and doing S.M.A.R.T. self-tests are essential. If you keep having trouble, try other methods like using rsync or getting a newer storage device.
