    Hi,

    And Merry Xmas Eve to all,

    As I move forward and start using Blu-ray for archiving audio and video
    projects, does anyone have any info on what blanks to use ort stay away from

    I've been using Taiyo Yuden for CDs because of the overwhelming anecdotal
    info that they are better and suffer fewer coasters. That's been my
    experience as well.

    Thanks,

    Ty Ford

    my experience too, ty seem very good....

    curious that you're using blu-ray though. why not external hd's?

    i only ask since i've been using small capacity usb 2 external drives (
    per project, cost is minimal) for years without a single incident. on
    the other hand not only have i found some old(er) cd / dvd's error
    prone, but incredibly slow to load anything but small projects....

    And given the tighter tolerances required for Blu-Ray, I doubt they would be
    any better at long term storage without error. I do however keep my backups
    on both Hard Disk and DVD in the hope at least one will last. Given the
    current cost of BluRay disks, I haven't been tempted to go to HD and BluRay
    just yet.

    economy of space and having had issues with mechanical hard drives. I had one
    that wasn't more than several years old and not used for much but backup that
    I had to coax into mounting (click, click, click) by unplugging it, powering
    it down and smacking it soundly before reconnecting and powering it back up.

    Regards,

    Makes the point that hard drives, both old and new are prone to fail on the
    shelf.

    IME optical media does well in the proverbial cool, dry, dark place.

  6. Blu Ray tech itself has been proven by the broadcast industry to be
    particularly robust in field use. Of course the Sony cameras that use it
    have a cartridge loading disc but they are down to about $15 a disc. Wonder
    if there are affordable computer drives for those discs. Many local
    television stations with news departments reuse these discs over and over
    week after week and they have proven robust. Don't know what archival shelf
    life is like? Might be worth examining.

    Did you smack it on the top or on the side;-)

  8. I recently went through my big box of hard drives I've been collecting over
    the last 15 or so years and decided to try to mount them all and make sure
    there was nothing of value on them as they all had sharpie markings with
    stuff like OLD C Drive from Win 98SE machine with a date. So it was a walk
    down memory lane of 10GB, 20GB hard drives of various flavors for the old
    days. Some of them spun up, some of them clicked etc. I tried freezing and
    thawing, hittling, slapping, dropping and various other flavors of anecdotal
    drive saviour and not a one of the drives that wouldn't spin up would ever
    spin up.

    IME a lot still fail, but often due to the fact that discs probably had a
    high error rate to begin with. You have to be certain the discs you are
    storing are not only good quality, but your drive is writing to them near
    perfectly. Once you have a good drive/disc combination, you still need to
    check it on a regular basis at least. I'm amazed how many people have never
    done it, and assume just because a disk is readable all is fine.
    However I do not think storing hard drives is any guarantee either, having
    both gives you a better chance IMO.

    Common problem unfortunately, yet I have a 20 year old drive still working
    fine in a box used nearly every day. The mechanical parts, and even some of
    the electronics like capacitors, like to be powered up now and then, not
    left on a shelf indefinitely.

    IME failing CDs have all been mistreated and somehow missed out on their
    siestas in those proverbial cool, dry, dark places. I don't think I've ever
    had a pressed CD fail to read. CD-Rs have been a little dicey, but the
    failing discs were not stored properly. I also had a few dozen CD-Rs that
    were never burned fail in storage, but again they were stored casually.

    I've love-patted and burped any number of hard drives into their last
    productive session. I start out with patting on the sides and then go to the
    top if that doesn't work. Also temperature cycling, first warming naturally
    to above room temperature and then a trip through the freezer.

    I have been on similar fishing expeditions, but had a little better luck.

    I think we agree on the general truth being that you *can't depend on hard
    drives* to *not* fail while powered-down on the shelf. I've seen optical
    drives pull the same irritating stunt.

    The good news is that if an optical drive fails, you can still play the
    media some place else.

    Have you tried rotating the enclosur sharply about the spindle axis?
    That works in a surprising number of cases.

    No, but I will the next time my love pats don't work. Thanks for the tip
    even though I'm a little dubious about it. Time will tell! ;-)

    I'm getting ready to go through about 50 bad drives one more time before I trash
    them, so I'll give this technique a test. By the way, if you decide to trash a
    drive, open it up and remove the gigantic magnet. It is a FABULOUS magnet for a
    variety of uses.

    Steve,

    I'm certain that's proprietary information.
    Smacking the box: N/C
    Knowing where to smack the box: $!

    :)

    Season's Best,

    Ty Ford

    I've had a few that failed to read properly from new, especially a decade or
    two ago. Things seem to have improved in the pressing plants since then.
    Nope, seen many cheap discs written on cheap drives that were once readable,
    stored properly (well dark storage, never used at all, no severe humidity or
    temperatures), and are now quite useless unfortunately.
    (not difficult to find pristine unreadable Princo disks for a start) :-(
    However my good quality discs that were burned on a good drive and tested
    for low error rates, still seem to be fine after 2 decades.

    Trevor.

    Some drives have visible spindle ends, I imagine you'd have even more luck
    using a friction coupling of sorts to actually spin the platters before
    powering up when possible.
    Of course when all else fails, just pull them apart, clean, and lubricate.
    You may not have a clean room, but when you have nothing left to lose...

    Even the best discs written with good drives are no guarantee. Although the
    life of the disc can be shortened by improper storage, that isn't the only
    issue. CD-Rs (DVD-Rs, etc.) depend on the contrast of the dyes to discern
    between pits and peaks, and dyes have both light and dark fading
    characteristics.

    This article provides an easy-to-read overview of the issues:
