Hi @John1108

Welcome to the HP Forums!

It is a great way to engage, post questions and find resolutions by working with specialists in the HP community.

I reviewed your post and I understand that you want to know how to improve the data transfer speed.

I’d love to help!

I would like to inform you that the data transfer speed usually depends on a lot of factors, like what data you are copying, your computer speed and configuration.

Here are few steps you have can perform to improve the data transfer speed.

Set Your USB Drive to Better Performance

Windows defaults USB drives to use a “Quick removal” data transfer policy. This disables write caching, which slows down transfer speeds, but lets you disconnect a device safely without using the “Safely Remove Hardware” prompt.

To disable this feature, do a Windows Search for Device Manager, and open it. Expand the Disk Drives tree and locate the USB drive you’d like to improve (it must be plugged in to the PC). Double-click the drive’s icon and, in the window that appears, find the Policies tab. Click the “Better performance” radio button and then, underneath, check the “Enable write caching on the device” checkbox (some devices don’t support this, however). Then click OK.

Remember, if you enable this feature, you will have to remove the device from within Windows before unplugging it. Failure to do so can result in data loss. To make this easier for you, right-click on your desktop and create a new shortcut, then enter the following as its path:

%windir%\System32\control.exe hotplug.dll

This creates a shortcut that takes you directly to the Safely Remove Hardware menu.

Change the File System

The file system you use to format your drive can have an impact on performance. Many come from the factory with conservative formatting that allocates data in small chunks, which in turn maximizes the drive’s storage capacity. Increasing the size of these chunks, however, can improve performance.

If you use Windows, you’ll want to use the NTFS file format with an allocation size of 64 kilobytes. This is the quickest configuration for a modern Windows PC. If you also need to use the drive with DOS, Mac OS X, Linux or your a device like your TV, FAT32 is the right choice, and it too can be set to an allocation size of 64 kilobytes.

Formatting via Windows is simple. Just open My Computer, right-click the USB drive, and click format. A menu will open in which you can change the file system and allocation unit size. Set each to what you desire, then click Start to begin formatting. Remember, as with any format, this will delete all data on the drive – make sure nothing important is on it before you begin!

Disable Legacy Mode in BIOS

Extremely slow transfer speeds are sometimes caused by a BIOS feature called USB Legacy Mode. This feature is meant to provide compatibility with old USB devices that otherwise might not work, but it can restrict transfer speeds.

The exact steps for disabling Legacy Mode will depend on your motherboard, but here are some guidelines. First you’ll need to enter the BIOS, which in most cases is performed by pressing F12 or Del when your computer boots (if you get to the Windows loading screen, it’s too late; restart and try again).

Let me know how it goes and you have a good day ahead.
