Windows 7: Fast copying External drive A to External drive B

Fast copying External drive A to External drive B

I have two external drives, one containing the data to be copied and the other to receive the data. The receiving drive already has a little data on it, which needs to remain there.

What is the fastest way to copy this data across?

I tried drag and drop. But the drive A contains 2.7TB of data. My calculations are that the transfer will take about 45 hours!!

Thanks,

Jon

No program is going to make it any faster most of it depends on your USB connection are you using 2.0 or 3.0?

Just recently I copied using Control C and pasting Control V from one external hard drive to another (using a 3.0 USB port and a 3.0 hard drive caddy) a little over 500 GB and it took less than an hour, when the copy window comes up and calculates how much time is remaining usually changes quite a bit depending on what it is copying and pasting at the time.

You could try RichCopy

It is multi-thread and avoids all that Explorer counting the files first business.

Although as Bongo points out, if you have slow hardware that will limit any transfer scheme. RichCopy was the only sane way I found to copy my Windows.old folder across the Lan to an external drive.
