My external drive is extremely slow copying music and data to my D: drive, the format of both the drives is ntfs, and my anti virus is not scanning, when I drag and drop from one to the other the copying is extremely slow.
Please not too technical thanks

Howto: Fix Slow USB 2.0 file transfer on Windows

USB storage devices can be optimized for either quick removal or performance. If optimized for quick removal, data transfer can potentially be reduced to a crawl.

To optimize your USB drive for performance:
  • 1.Right click on the USB drive and select properties
  • 2.Select the Hardware tab
  • 3.Under All Disk Drives, highlight your USB drive and select Properties
  • 4.Select the Policies tab and select Optimize for performance.
  • 5.Press OK twice, and your transfer speeds should increase dramatically

Note that when your drive is optimized for performance you'll need to use the Safely Remove Hardware icon in the taskbar to eject the drive - otherwise you'll risk corrupting your data by just removing the drive from the port.
Thank you

A few words of thanks would be greatly appreciated. Add comment

Hi Sgagliozze, it is possible that turning your PC of without disconnecting your external drive correctly can risk corruption.
Thank you very much I was suffering with this issue since a very long time
Thanks, I thought my hard-drive was a busted. I was getting 0Mb/s when transferring files, but this seemed to solve my problem! Simple but effective.
Life saver ! Thanx !

It works for me in 2020, the speed is now stable.
tried loads of things even microsoft recommended settings. found this great......its bloody works, thanks to the super brain who worked it out
Go to
1. Control panel
2. System and Maintenance
3. Administrative tools
4. Run services shortcut
Once the services program loads find the services called Background intelligent transfer service and stop it
also right click on the same service and click properties then change the start value to manual or disabled this should also fix the network problem and USB copy and paste problem
Amazing problem solved
Your solution works! Do I have to keep doing it for all computers I use my drive on?
thanks so much it worked for me. :)
Big problem, easy solution.....Thank you
Go to device manager & try optimizing the drive for performance.

Goto: Device manager/Disk Drives
Find the disk and right click for properties option.
Click 'Policies' tab'
Check "Better Performance"

That should solve the problem.
thanks bro....................
I also had problems with copying speed from an external USB drive to my internal one. But the problem only appeard for my movie folder on that disk, which seemed a bit odd to me and found a bit weird soloution to it:
I checked the information for the movie folder (apple+i) and compared them to the ones of a 'no problem' folder. For some reason the 'sharing & permission' section of my movie folder had two entries for me on saying 'read & write' and the other saying 'custom' above it.
I changed 'custom' to 'read & write' and everything went back to normal.

I now have reading and writing speed of 20 MB/sec. Before had 500kb/sec.
Don't now if this works for you, but it might be worth checking.
This may or may not address your problem. I just upgraded from XP to a new PC running Vista. MY external USB 2.0 hard drive used to work quickly
(30 MB/sec), but now was running extremely slowly (1.5 MB/s, if I'm lucky).

Vista would tell me that my device could perform faster if I connected it to a USB 2.0 port. Well guess what? All my computer has are USB 2.0 ports. Other ports were no help.

I tried all sorts of fixes, nothing was working. The hard drive would still work fast on my old PC.

One forum suggested that some USB cables don't fully support USB 2.0.

So I tried a different USB cable, and it works perfectly. 25.6 MB/s! Put the old cable on, and it was slow again, with the same error message. Put the new cable on, and it worked fast again.

So consider trying a new cable!
The USB cable did the trick for me as well. It worked perfectly fine after many months of agony.
I Dont Know If You Solved This Problem, But The Way To Fix It Is Change The Cluster Size To 512 Bytes, The Problem Is The Hard Drive Is Reaching Its Lifetime.
I had a similar problem. SMART was OK. Eventually, measured the read and write speeds. Write was 20x slower than read! Checking with Seagate disk tools showed that the drive was about to die.
It had also caused my system to slow in an unpredictable way. After boot it was fine but at sometime over the next hour it would slow. It turned out that I'd moved the temp file to this drive as it was supposed to be fast.
Hope this helps someone.
