transfer data through windows 7 by copy and paste perfect copy?


New Member
I have one internal drive with 1 TB.
The data there is very important to me , so I bought External removable drive for backup.
Now, I want to copy the data from one drive to the second drive but I have to be sure I have a perfect copy of the data.
The data is mostly songs movies and documents.
I'm using windows 7.

My question is this:

1.If I'll transfer the data through windows 7 by copy and paste, I could be sure i have a perfect copy?
2.There are tools for comparison Between the original data to the data that was copied?
If so, what are they?

If I do not in the right place please pass my message to the right place.thanks.

Windows Explorer will always copy with verify ON

If they are in folders just drag and drop the folders onto the new drive

If that is a seperate data partition, I would image it. Advantage is that it will get compressed and you need less space on your external drive. The easiest way is via Wbadmin in Command Prompt. That way you get a VHD which you can always attach with Disk Management. The Wbadmin command is:

WBADMIN START BACKUP -backupTarget:e: -include:d

where 'e' is your external disk (the image goes to the root) and 'd' is your data partition.:
