    hi Pufferine,

    well it is not a bug, since for me it works perfectly. Do you copy via Task scheduler?

    Anyway be sure you do it as Administrator to avoid some problems.

    Hi.
    How did you run the process? Click and drag, copy and paste, or other ways.? Did you install any utility that interfere with copy process like Terracopy, fastcopy, ultracopy, or else?

    try this: uncover the ext. hdd, and plug it to your motherboard via SATA.

    if it works, then the problem is in the circuits of the hdd.

    This is an alpha version. You cannot expect it to be perfect. I would not have spent 4 hours on the problem.
