New external exFAT hard drive and file copying issue

For the last few years, I've used two 4TB NTFS hard drives, attached to my PC (a Dell XPS8940 tower) via USB3, as file backup and archive drives. I recently purchased a Seagate Expansion 14TB External Hard Drive HDD to replace one of the two external drives. The new drive out of the box was formatted as exFAT, and I didn't change that (though in hindsight maybe I should have).

I successfully copied all of the files on the old drive to the new drive using the FastCopy utility. That took a few hours (there was about 1 1/2 TB of data copied), but the "cloning" ran smoothly. After that, I unmounted the old external drive, attached the new drive, and changed the drive letter and disk name to match the old drive's letter and name. So far, so good.

I'm now seeing an issue when I do an old-fashioned Windows Explorer copy of files to the new drive. I'm a serious amateur photographer, and I often wind up with a folder with more than 100 files (photos) totaling about 4GB in total size on an SD card. That happened today. I first copied the folder of photos from the SD card to the desktop of my C: drive, and that ran as smoothly as ever. Then when I copied the folder of files to the new external hard drive, the copy went smoothly and quickly until the progress bar showed about 61%. At that point, copying paused, the progress window showed "Calculating" and about 50 seconds elapsed before copying resumed. The copying progressed to maybe 90% when there was another, briefer pause, after which the copy completed successfully. All the files were copied, and the only problem I saw were those pauses during the copying.

When I copied the same folder of files to the old (NTFS) external drive, there were no pauses, so it seems to be an issue involving only the new drive.

As a test, I did an incremental backup of the new drive, once again using FastCopy. The backup, which included mostly the new folder of photos, ran fine and ran as quickly as I would expect. I have FastCopy set to verify all files that are backed up, and the verification showed no errors.

The bottom line is that large file copies done using Windows Explorer still run without any pauses on my older NTFS-formatted external drive, but when I do the same copy on the new exFAT-formatted drive, the copy pauses two or three times during the copy process. Both drives use the same settings (I double-checked in Device Manager). The Removal Policy for both drives is for Better performance, if that makes any difference. Also, there are no pauses when I copy files using FastCopy (which, unless I'm mistaken, uses some method other than the Windows Explorer routines to do its copying).

Is this sort of pausing when doing file copies to an exFAT external drive to be expected, or is there some problem with the new hard drive and/or its settings?

If it makes any difference, the PC has 64GB of RAM, and is running Windows 11 Home Version 22H2 (OS Build 22621.2070) (Windows Update shows I'm up to date).

Any insight would be appreciated.

It's important to note that while your Seagate Expansion 14TB External Hard Drive is formatted as exFAT, the formatting itself should not inherently cause the pauses you're experiencing during file copies. ExFAT is designed to be compatible with both Windows and macOS and supports large file sizes and drives.

Given that your FastCopy utility doesn't exhibit the same behavior, it seems more likely that the issue lies with how Windows Explorer handles the file copy process. Windows Explorer might perform additional checks or operations during copying that could introduce pauses. Here are a few more suggestions:

1. Disable Thumbnail Generation: Windows Explorer generates thumbnail previews for media files during copying. Disabling this feature might help improve the speed and consistency of the copy process. To do this, go to Folder Options > View tab > "Always show icons, never thumbnails."

2. Update USB Drivers: Make sure you have the latest USB drivers installed for your system. Outdated or incompatible drivers could impact the performance of external drives.

3. Try Different USB Ports: If your computer has multiple USB ports, try using a different one. Sometimes, certain USB ports might have better performance due to how they are connected to the motherboard.

4. Experiment with a Different File Manager: You might try using an alternative file manager to see if the pauses occur there as well. This could help determine whether the issue is specific to Windows Explorer.

5. Run Disk Checks: Perform a disk check on your Seagate external drive to ensure there are no file system errors that could be causing the pauses.

6. Test on Another Computer: If possible, try connecting your Seagate drive to another computer to see if the pauses still occur. This could help determine if the issue is specific to your system.

If none of these suggestions resolve the issue, it might be worth contacting Seagate's support for further assistance. They could provide insights into any known compatibility issues or specific settings that might help optimize the performance of your drive with Windows 11.

First, thanks for the detailed response.

The drive in question stores mostly photographic images (more than 80,000 of them), and I need to be able to see the thumbnails, so disabling thumbnail generation isn't an attractive option. Once a file copy completes, the thumbnails show up as expected, and quickly. Besides, the old NTFS drive it replaced had that option enabled and it never caused any pauses or any other issues. And another NTFS-formatted external USB drive, about five years old, doesn't have these file-copying problems and it also has thumbnail generation enabled.

2. Update USB Drivers: Make sure you have the latest USB drivers installed for your system. Outdated or incompatible drivers could impact the performance of external drives.

The USB drivers, and all other drivers on this PC, are up to date. I'm pretty conscientious about that.

3. Try Different USB Ports: If your computer has multiple USB ports, try using a different one. Sometimes, certain USB ports might have better performance due to how they are connected to the motherboard.

The PC has multiple USB ports but they're all already being used. I use the USB ports on the back of the PC to attach the two USB drives, having read that that might make a difference.

4. Experiment with a Different File Manager: You might try using an alternative file manager to see if the pauses occur there as well. This could help determine whether the issue is specific to Windows Explorer.

I'll keep this suggestion in mind, but I'd rather not mess around with other file managers yet. With all its limitations, Windows Explorer has always been adequate for me until now.

5. Run Disk Checks: Perform a disk check on your Seagate external drive to ensure there are no file system errors that could be causing the pauses.

I'll also keep this in mind, but given that file copies using FastCopy run perfectly quickly and smoothly, I'm not expecting much in the way of enlightenment.

6. Test on Another Computer: If possible, try connecting your Seagate drive to another computer to see if the pauses still occur. This could help determine if the issue is specific to your system.

This isn't a particularly viable option. I'm a home user, and other than a really old and feeble laptop, there's no other PC available for this sort of testing.

If none of these suggestions resolve the issue, it might be worth contacting Seagate's support for further assistance. They could provide insights into any known compatibility issues or specific settings that might help optimize the performance of your drive with Windows 11.
Again, thanks for responding. I'm still hoping for some Windows setting I've neglected that might resolve this one issue I'm having.
