Windows 10: File transfer rate question (starts off good, drops to 0, then accelerates)

I frequently transfer audio files to a USB drive and have noticed something odd about the transfer rate: it always starts off relatively high, continues at that rate for a while, drops off rapidly to near 0, then gradually ramps back up. Why is this? I suspect it's due to a buffer of some kind filling up, but is this a software or hardware limitation? The USB port and drive are both 3.0:

How to change the drag & drop default bit rate to transfer audio files?

Hi,

Thank you for posting your query on Microsoft Community and sorry for the delayed response.

In order to assist you better could you please confirm a couple of things:

• While dragging and dropping do you get an option to change the bit transfer rate?
• If yes, have you tried changing the bit rate?

If you get an option I suggest you to try changing the bit rate manually while dragging and dropping and check if this helps. Also please be informed that its by default your files are being transferred with the bit rate 160 kbps. So you may leave a feedback
by using the Windows feedback App.

Hope this information was helpful and do let us know if you need further assistance. We will be glad to assist.

 

Disk Active time 100% Disk transfer rate 0

This is a problem I've seen reported countless times, on Microsoft support sites and elsewhere. Task Manager shows "Disk Active time 100% Disk transfer rate 0", and everything that's running on the computer freezes, although sometimes you can switch windows,
or even perform some operations within a window, but other times
everything freezes, including the mouse pointer. It usually lasts for 30 or 60 seconds, but sometimes it goes on for several minutes. Then it stops and everything goes back to normal, including Disk active time and Disk transfer rate.

It happens regardless of the apps I'm running or the activities I'm doing. I've even seen it happen with no user apps running at all - no browser, no file manager, nothing but background stuff. It happens every single day, regardless of whether there has
been a Windows update installed.

Microsoft gave me a fix for this problem a week ago, but it didn't work. Here are the steps I followed:

at admin command line prompt:

• Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
• dism /online /cleanup-image /restorehealth
• reboot
• find driver file for Intel(R) 9 Series Chipset Family SATA AHCI Controller
  • C:\WINDOWS\system32\DRIVERS\iaStorA.sys
• Details tab from Properties window for controller
  • Device instance path:
    • PCI\VEN_8086&DEV_9C83&SUBSYS_06B01028&REV_03\3&11583659&0&FA
• find registry key for disk controller
  • Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\VEN_8086&DEV_9C83&SUBSYS_06B01028&REV_03\3&11583659&0&FA\Device Parameters\Interrupt Management\MessageSignaledInterruptProperties
  • change MSISupported from 1 to 0
• reboot

The instructions I was given include this for Step 4: If you see “StorAHCI.sys” in the list, you are running the inbox driver. But my driver is iaStorA.sys, so maybe this
fix doesn't even apply to me.

After doing all of the above, twice, I still have the problem. I've seen this now over a period of about three years, on two completely different laptops, one a Toshiba running Windows 8.1 and currently on a Dell running Windows 10. I also have a Thinkpad
for work that runs W7, and I've never seen it happen on that machine. It got so bad on the Toshiba that I ended up discarding it, after spending countless hours trying to fix it.

I've also tried all the fixes I've found on the web, e.g. disable superfetch, disable BITS, add write permissions to Skype and the browser. Nothing I've found so far has helped. I also reverted Windows back to build 1703. That didn't help either.

 

Flash drives File transfer speed drops to 0 regularly

Long shot.

Plug in the USB thumb you normally use, the erratic one. In My PC, make a note of it's drive letter. Eject it.

On the machine in question, the one that is acting weird, go to Device manager.

Click Portable Devices. Look for that drive letter and uninstall (right click>uninstall device) any and all occurrences of it.

Plug the thumb drive back in. Windows will reinstall the driver/device.

Try your operation that was running weird with the fluctuating speeds.
