incredibly slow win 7 usb transfer rate

February 3, 2011 at 14:51:53
Specs: Windows 7, 2 gb
I saw this post and seem to have the exact same problem:

I was wondering if anyone had come up with a solution or reason. I was actually transferring files just fine from my usb port to my portable hard drive, getting speeds of about 18-22 mbps, up until a few days ago. I was transferring 2 gb files in 4-5 minutes--then, as of a few days ago, whenever I try to transfer anything speeds start at 28, drop to 16, drop to 8, then drop a half mb every few seconds until it shows it will take 50 mins to transfer a 2 gb file. this is maddening! can it be a virus? I do use an antivirus program, but I am an active downloader, and I know there are "invisible" viruses that can't be seen with task manager.

I have also tried to change the properties of the portable HD to optimal transfer, or whatever it's called, to make it faster, but that didn't help at all. please help!
thank you!

Does it show as a usb 2.0 still. It seems like it fails to usb 1.1 from the times.

nothing has really changed on my computer. how do I check to see whether or not it's being seen as a 2.0 or a 1.1?

Find out what key or combination of keys you need to hit during start up to into your BIOS set up screen. In there you will have settings for your USB ports. Make sure you are set to 'high speed USB' or 'USB 2.0'. You will find the information on BIOS set up if you download your system's manual from the manufacturer's website.

You have to be a little bit crazy to keep you from going insane.

hey was having the same problem, what i did and it seems to work is:
1. plug in your device
2. go to device manager ( right click my computer then go device manager )
3. click on device ie disk srives for usb hdds
4. right click your drive name go to properties
5. click on policies tab
6. click better performance which is not the default
7. need to restart machine.

usb 2.0 is only faster because it caches info before writting hence need to have this option ticked.
take note that you will need to "safely unplug your usb device" google this if not known how to though, which is probably good practice anyway.
