Problem moving data from one drive to another.

I am attempting to move all of the data contained in a partition to another hard drive new partition. When I select all of the files on the old hard drive and attempt to move then to the new disk (new partition) the program tells me that the transfer was successfully completed.

BUT when I compare the sizes of the partitions a GB of data was not transfered. I even tried using Partition Magic to move the old partition to the unallocated space on the new hard drive (Partiton Magic automataclly creates a partition for you before moving the data). The software told me that a quailfer was missing (of course it didn't tell me which one) from the move(?) partition command. Still a GB between the two drives is not transfered.

In this file transfer setting there are two NexStart 3 external hard drive enclosures. In one enclosure there is a IDE drive the other enclosure holds a SATA drive.

What am I doing wrong?

Not sure I am understanding what method you used to move the files.

If you have V10, you can do an image backup of the old partition and then restore it to the new partition.

 

Thank you GroverH for replying!
