    I bought tow larger hard drives for myself, both advertised as Ultra DMA 133,
    and put them off of my raid controller. Yet when I look in my controller's setup
    screen it shows them as Ultra DMA 100. My previous smaller drives show properly
    as Ultra DMA 133. Does anybody have any idea why the raid controller does not
    see them as supporting the 133 speed ?

  2. Who makes the drive?

    More than likely, the drive does not support Ultra DMA 133.
    If its a western digital drive, that is definitely the case.

    In actual performance terms this makes precisely bugger all difference, so
    ultimately it's not worth losing sleep over.
    Are you sure they're UDMA133 drives? The only manufacturer who makes drives
    supporting this standard is Maxtor.

    If they are Maxtors, then the likeliest reason for not running at "full"
    speed is because this mode is disabled by default. Download the appropriate
    feature tool from Maxtor's website and see if you can enable it.

    If the drives *aren't* Maxtor, then they were advertised falsely. However,
    it is unlikely to be worth doing much about as the chances are that the
    drives you've bought actually perform better than the Maxtor equivalents.

    I am probably confusing two things. What is the difference between "Ultra DMA
    133 MB/sec" and "Ultra ATA133" ? The two new hard drives I bought, "SAMSUNG
    SpinPoint P Series SP1614N 160GB 7200 RPM IDE Ultra ATA133 Hard Drive - OEM" is
    listed as the latter in the NewEgg web site description.
    The two smaller hard drives I have originally were Maxtor's, listed where I
    originally bought them, as "Maxtor DiamondMax Plus D740X 6L040L2 40 GB Ultra
    ATA/133". The Maxtor drives show up in the raid controller as ATA133 while the
    Samsung drives show up as ATA100.

    This bothers me very little but I wanted to understand the difference vis-a-vis
    what the raid controller sees.

    It is a "SAMSUNG SpinPoint P Series SP1614N 160GB 7200 RPM IDE Ultra ATA133 Hard
    Drive - OEM". I am probably confusing "Ultra DMA 133" and "Ultra ATA133".

    Well... since you're not losing sleep...

    UDMA 133 MB/sec and Ultra ATA133 are functionally the same thing.

    Samsung has a utility, available here .. (it's a long link) :
    http://product.samsung.com/cgi-bin/...e=N&oid=67196&cntType=SW&cntId=221010&lang=EN

    ... which, among other things, allows you to diagnose problems, perform a low
    level format, set the UDMA mode, etc.

    Hutil.exe and it's configuration file are contained in the above download.
    You run the extractor and direct it to a folder on your system. It's a
    DOS-based utility and probably would best be run when booted to DOS
    (personally I wouldn't go fiddling with my hard disk's firmware when booted
    to anything other than DOS).

    The manual for the utility is available here:

    Stupid question that mist be asked.... You are using an 80-wire IDE
    cable, and not the old 40-wire type, right?

    Hi DrWho -

    He'd be limited to ATA-33 with a 40-wire IDE cable.

    ATA-66 and above requires 80-wire IDE cables.

    As with Maxtor drives, he probably needs to use Samsung's proprietary
    utility to 'change' the DMA setting to ATA-133. And, as Richard has already
    said, the result will be negligible, at best, as burst speed has very little
    bearing on overall performance.

  9. I'm afraid that is a stupid question, as if the OP *was* using a 40 wire
    cable, he'd be stuck right back down at ATA33, not ATA100...

    Thanks for the links. I guess it would have been smart of me to first look at
    Samsung's site for my hard drive <g> to see what could be found for it and about it.

    No problem. Always happy to nudge others to the obvious. ;-)
