Large file transfer stops working when using USB hard drive and Windows 7 64 bit, Intel chipset

Sounds like there may be a driver loading when not in safe mode that's causing this issue.

Please run the application msinfo32 on your machine and follow the steps in the app to save the output to a file.

Then post that file in a public folder on http://skydrive.live.com and post the link here.  I'd like to see what other apps are installed.

Thanks Again

Thanks for posting that.

In that file, I see that drivers for Acronis were still installed and the app itself was still in your startup folder.  You might want to try uninstalling the app again, and make sure the drivers are removed when the app is gone.

I see a few other apps that would also be involved in file transfers:  Avast antivirus, a-squared free antivirus, NTI backup Now, and MyWinLocker encryption software.

I'd suggest uninstalling the apps individually to see if it's isolated to a specific one.

For avast, you should be able to uninstall that on a temporary basis to see if that resolves your problem.  I also see a service named "a-squared free", which appears to be another antivirus app.  Do you have 2 AV apps installed?

For MyWinLocker, I'm not sure if it's that simple.  You probably have to follow some process to decrypt your files before uninstalling the app.  I don't know anything about this app, so unfortunately I can't guide you on the appropriate uninstall steps.  You might want to check their website to see if they offer suggestions on the best way to do this.

It might be worth trying RichCopy as a test.

I uninstalled all the programs you suggested, unfortunately it would now lock up the computer at the start of a large file transfer and force a reboot.  I am not sure why safe mode works . If I am in msconfig and disable all the non microsoft services and all the startup items , what is safe mode doing differently. Maybe I could start looking there. Going through items one at a time until I find it. I am just not sure where to start.

I also downloaded  a copy of richcopy as suggested. It transferred 921mb of file in six directories with no problems from the USB drive to the computer.

 As I said earlier, I can write large files to the USB hard drive. The problem occurs when I try to copy large files or groups of files from the USB hard drive to the computer.

Thanks for your efforts. Please keep the suggestions coming. From what I am reading , I am certainly not the only one with this problem.
