Windows 7: Why does copying files start fast then slow down so dramatically?

MSconfig doesn't disable antivirus.
Try a test booting in safe mode.

OK... I can try, thanks: but to be honest I don't think that's the issue. Why not? Because I have been copying all day and since the mid-afternoon (that's five hours now), the transfer has been running at 30-40MB/s non-stop. With anti-virus on. Had I turned AV off, I would have thought I had found the problem. Easy to make quick conclusions!

Normally AV protect it self and it can't be turned off by MSConfig.
Safe mode doesn't load all auto start programs, including AV.

I am currently backing up files in preparation for my new hardware. I am copying file from a samsung F1 1Tb drive to another identical drive. I thought that these drives were fast, capable of around 40mb/s but atm the process is only managing 19mb/s.
