My source drive has a capacity of 1 TB. Get info shows that tha capacity is 966,23 GB of which 141,14 GB —141.144.903.680 bytes— are used.

My target drive has a capacity of 1 TB. Get info shows that the capacity is 996,86 GB. It is USB2.

How many hours may it take to do a CLONE? Approximately?

    Which machine? How much RAM. For FW 400 the rate's about 1 GB/min running on a late model iMac. double that for USB.

    Thanks a lot, I will start that this evening so that it runs all night if needed. By the way my machine is an iMac 27" 2.66GHz quad-core Intel Core i5 with 4GB RAM.

    It will be a bit faster. My 27" iMac i7 w/FW 800 is twice as fast. I strongly suggest getting a FW enclosure. I have the Macally GS350SUAB which has FW 800 and can hold SATA HDs. Mine's a Hitachi 1 TB Deskstar SATA 7200 RPM #HD31000 IDK/7K.
    That should be two to three times faster than USB 2.0.

    I am upgrading my 20" iMac with 250 GB Hard Drive to 1TB. Since I had more time than money I purchased a Coolmax 3.5" External Enclosure (Model: HD-389-U2(SATA)), USB 2.0, from for $15.00 (since I spend so much money with Amazon, I get free 2 or 3 day shipping). I enclosed a 1TB 32MB SATA 7200 RPM Seagate Barracuda Internal Hard Drive. I used the Carbon Copy Cloner (CCC v 3.3) , To transfer nearly 250 GB to the 1TB target HD.

    It took about 2 minutes per GB or a Total of about 8 hours. I started it before going to bed, and it was done when I got up in the morning.

    Once you have your initial clone completed, subsequent clones that only copy changes will be much faster. Mine are typically less than 30 minutes.

    Average for FW 800 to external HD from a 27" iMac i7 w/12 GB RAM is about 1.5 GB/minute.
