  1. I am planning to put my burner to external enclosure. It should be Firewire since I have Firewire on home PC and Laptop (no USB2 only 1.1). I found this one on the web.

    CD-509 5.25-inch Firewire External Enclosure Case for $48 (Genesis or somethink like that chipset)

    Is it good one ? Or is there something that is tested and for good price ? What should I check before I buy one ? Is there somthing that I should avoid ?

    Thanks.

  3. There are some dual firewire/USB2 enclosures out there also that might be worth a look.

    everyone knows that -> a "thick Moderator" is used to shield Neutrons in a reactor or also to slow down a radioactive proccess or chemical proccess. You could use a thin one also - if you got guts..

    oh and used to block gamma rays also (VERY difficult - don't try this at home!!)

    Good moderators are generally hydrogenous materials, so a fat cat could be considered a thick moderator.

    BTW, very dense materials are usually used for shielding gammas and in general are not good moderators (at least in the nuclear sense).

    Yes, BJ's links look to be great if you like overpaying for
    enclosures. You can get oxford911+usb2 combo enclosures through etailers for about $90. For example:

    http://www.triumphtech.com/@PRDCT/TT345.htm

    which is what I got for my dru500a.

    I've seen this enclosure resold elsewhere for basically the
    same price, but usually for more money. The firewire only
    enclosures are a bit cheaper.
    Also non-oxford 911 enclosures seem cheaper, and
    skimping on power supply (getting one that is under-rated)
    can probably save you a few bucks.

    Note that firewire bridges don't necessarily handle IDE errors
    the way one would expect (mine doesn't report CRC errors that
    occur on read or write). Here's my rant on that topic from another
    thread:

    I think there are a couple dirty secrets about IDE/Firewire bridges. (I
    suspect the same is true of the IDE/USB2 bridges but I have no experience).

    First, configurability. People have problems with firewire enclosures due to
    things such as which UDMA mode is negotiated, and how many seconds the
    controller waits before probing the device. Oxford's firmware utility lets
    one configure such parameters, but the utility has not been made widely
    available. I see no enclosure retailer who supports configuring the firewire
    bridge through such a utility, even though one may very well need to in order
    to get their device to work. These enclosures are marketed as if they
    are plug and play, but they aren't necessarily.
    [Update: apparently adstech does allow configuring the device type in
    their oxford 911 based enclosure.]

    Second, error detection and correction. When I first put my dru500a in
    a firewire enclosure, I got a bit error every 2MB or so during DVD writes.
    My writes would be corrupt without any error being reported. Tracked
    the problem down to the IDE cable being too cheap, producing cross-talk.
    An internal IDE controller would detect such errors.
    Later, I attached an IDE disk into a firewire enclosure. The disk contained
    data errors. With the firewire enclosure, the OS read past the errors
    with no error reporting (data was merely corrupted on read). Plugged
    in internally, the IDE controller reported CRC read errors for this same
    disk...

    Does USB2 have these same problems? If not, it is clearly the winner.

  10. bac, are you saying that Firewire enclosure is not good for DVD Writers ? I am cofused.

    What would be disadvatage if I buy non-oxford 911 enclosures ?

    I am not sure what do you mean by "skimping on power supply (getting one that is under-rated)".

    i have burned 100's and 100's dvd's in firewire enc. with no problems.. i suggested the more expensive cases because they have heavy duty power supplies , bearing fans (and dual fans in some cases) , and ata 133 rated internal cables , proper shielding of both the case and also the power supply IN the case.

    there are cheaper solutions, i just know what works ..

    firewire drives and dvd burners are used by 1000's and 1000's of people and are very popular in the video editing bussness.. as well as on apple computers (who invented firewire) ..

    it is true accessing an external firewire hard drive - there is delay .. some are better and some are bad (maxtor bad , acom good for example) .. we have around 100 external firewire hard drives floating around here , i have 8 x 120 and 160 firewire external drives hooked up right now along with 2 dvd burners -- and they are all going at once (burning two different dvd's same time) .. this is off a ads pyro card with the extra power supply cable attached to it ..

    Manufacturer link - http://www.a-tec.com.tw/ourproducts41.htm

    The $48 CD-509FW looks best to me and here is the USB 2.0 model - CD-509U2 for $45.

    http://shop.store.yahoo.com/4itech/cool35usexen.html

    I can't find one which sells CD-509Combo.

    I'll also use Sony DRU-500A in Firewire/USB 2.0 enclosures. It's South Korea's voting day for the presidential election so I'll get them tomorrow.

    oh -- i have one of those exact cases in BAC's post from http://www.triumphtech.com/@PRDCT/TT345.htm (same case but i got it shipped to me by esbuy (by mistake))..

    going to test it out tonight ... first i notice is it has a bushing fan and only a small looking 2.2 amp power supply vs a larger one on most of my other cases .. but it does have the very latest firewire bridge board made by rainbow -- who makes good parts ...

  14. Waiting for your testing results ....

    Is your FireWire ?

    And what about this Genesis chipset ? Is it bad ?

  16. More and more confused (maybe it is because I wan't chep one )

    These are that I found

    TT-345 Series (OxFord 911) $69
    CD-509-FW Series (Oxford-911) $53
    ME-320F (Oxford-911) $49 (you can see this everywhere but nost sites does not provide info about Chipset)

    Now I hate this on the web

    We are not responsible for typing errors. All information in the web are for reference only, please go to manufacturer web site for more detail information
    Do they have Oxford-911 chipset or not ? Does anybody have ME-320F ?

    BTW: Who manufactores these ?

    I am not sure what do you mean by "skimping on power supply (getting one that is under-rated)".
    External firewire can be a problem, in that it masks data errors.
    For example, when I first tried my dru500 in an external
    case (with oxford911 based bridge), I had a cheap IDE cable.
    The IDE cable had wires that were split, and could overlap.
    This created crosstalk, and generated ~1 bit error every 2MB or
    so. The IDE controller in the oxford911 chip did no error
    detection, reporting, or correction. The errors were passed to
    the DVD-R disks silently. Ie errors in your burn result.
    Took a couple days to figure this out.

    Pre-oxford 911 bridges were reported to be lower in performance
    than the 911. (For example the oxford 910). I am not
    sure about the current generation of alternative bridges, such
    as the initio. I haven't seen any performance test results for them.
    An example enclosure with initio bridge:
    http://www.ioiusb.com/products/prod_detail.asp?ProdCategory=USB_to_IDE_Enclosure&ProdN...=U2FWEIDE525-1


    By skimping on power supply, I mean one whose 12V and 5V amp output ratings are not sufficient for a 4X DVD burner. The
    DRU500s label has higher requirements than what I've seen
    on any other burner so far (not that I've done a study), so I
    wouldn't assume any 5.25" enclosure's power supply will do.
    A power supply that barley meets the current requirements of
    the DRU500 could burn out quickly I'd think. I had an external
    enclosure power supply burn out on me a few years ago...

    Glad to hear you've been lucky with your firewire experiences.
    Data write errors may be rare. In my case the cable was 40
    conductor but the bridge board was allowing UDMA3/4/5,
    which means a mismatch. I've read that such
    a mismatch can lead to data errors. Which goes to my point
    about configurability of the bridge boards.

    Anyways, such pitfals can exist even if thousands of non-technical
    users are bying the gear.

    Also note that I experienced CRC read errors
    not being reported by the firewire bridge board when I was
    reading from a hard disk with known disk errors. At that point
    I was using a quality 80 conductor IDE cable.

    Only had problems with Alcohol 120% but Nero, RecordNow etc works just fine.

    bac - you are certanly correct in that there is often a problem with cables -- not only in external cases but i have seen a very large % of pullout drive bays (you know those plastic drive sleds) that have a lot of problems with bad data and bad transfer ... due to one; they introduce an extra connection in the middle of a ide cable , and not a very good one at that . And second ; they often use cheap cables internally (like those split folded cables are the worse) ... i have seen many times an ata 133 cable external and internal they are just 40wire.

    i also have seen a number of bad ide cables -- specially some of those rounded designer cables are verry cheaply constructed ...

    AS for the oxford chipset -- be aware that Oxford 911 bridges can differ in overall performance (firmware may be an issue here); and, second, other new-generation FireWire bridges, such as Indigita's, can match Oxford 911 performance.
    Newest versions of oxford and Indigita do error checks i understand (and are ata133 internally).

    Some older oxford chipsets do not work at all on mac os-x and this is a problem for a lot of mac users..

    cant wait for serial drives ...


    but all in all - firewire is a great way to go

  29. I have a external 3.5 firewire enclosure from http://www.firewiredirect.com. It has the Oxford 911 chipset in it and I'm not at all happy with its overall performance. I don't know whether its the 911 chip or the internal cabling or the enclosure firmware but it's nowhere near 40 MB/s.

    The enclosure itself is very nice looking and made of good quality parts.
    Here's a link to the enclosure. I have the 3.5" Ultra III with FireWire & USB 2.0. http://www.firewiredirect.com/firewire/products/drivekit.shtml
