    Thats what I was implying. I actually meant to back them up before I
    removed my drive to take it on holiday to see some rellies, never got round
    to it. They should have been backed up to CD or DVD like the rest of them
    were. The External HD is IMO a very fragile backup media, and not to be
    relied on. Cheers

  2. Interesting; but having lost a whole weeks trip of photos a couple of
    In your scenario the original and the copy have an identical directory
    sturcture, right?
    Just do a recursive directory listing for each, redirecting STDOUT into
    a file. And then use diff to compare the two listings. Tells you exactly
    which directory entries are missing or additional in the second listing.

  3. Yes thanks, Eric, I used to be quite good at command line and batch
    files. However, I'm under the impression that these deduping programs
    search the whole directory structure and report on dups. I need
    something that searches the whole structure and tells me that there
    'isn't a dup' in the zipped archive or something. (I take your point
    though re attribute flags.)

    But you are right - I need a bit more lateral thinking on this.

  4. Thanks Len, noted. I'll investigate.

  5. Yes that was what I'd set up, but have adopted something different now.
    Need to rethink, perhaps!

    Solid and undeniable examples to the contrary would be off topic.

  7. You base your OPINION on your own limited (yes, limited) experience.

    Do a little research ( Google "hard disk failure rates") and you'll find
    that hard disk failure is extraordinarily common. The old industry adage
    "it's not a matter of IF, rather a matter of WHEN" is as true today as it
    was in the early 80's.

    If you take the oft quoted Industry Average failure rate of 2% (an extremely
    low figure based on real world analysis) and a worldwide PC production of
    150 million units annualy, each containing at least 1 hard disk then we're
    looking at a minimum of 3,000,000 hard disk failures IN BRAND NEW computers
    each year. Imagine what that number would be in the billion or so older
    computers around the world.

    Wake up, Tony. Listen to the advice of someone with 51 years of real world
    experience. Hard drives fail. Yet I would agree that an external hard drive
    backup system is the best alternative. The keyword being BACKUP.

    Of course I do. That's what an opinion is. I also hold the opinions
    that okra is detestable, that certain TV shows are unwatchable, that
    the Pontiac Aztec was an ugly car, and that Sarah Palin is unqualified
    for national political office.
    At no time have I said that hard drives do not fail. I have said that
    *my* hard drives have not failed, and I have recommended that an
    external hard drive is a good way to provide backup. I did not say
    they were the only way, or the single way, to provide backup.
    I don't know what specific experiences you are referring to, (but know
    that it *isn't* in the use of external hard drives) but my real world
    experience in some areas is 20 years more than 51.
    Then you have no reason to disagree with my comments.
