Hitachi Deskstar 7K3000 chips inward design.

Discussion in 'Asus' started by Skybuck Flying, Apr 27, 2011.

  1. Hello,

    This seems like a pretty sweet drive to me, especially the 2 Terrabyte
    version since it won't have any issue's with the 2.2 barrier limit.

    The only thing which bothers me a bit is it's inward chip design which can
    be seen here (1) and here (2):

    1 (English):

    2 (Chinese):

    http://article.pchome.net/content-1298165.html

    The product's official website seems to have no real pictures of it which is
    a bit suspicious:

    http://www.hitachigst.com/internal-drives/enterprise/ultrastar/ultrastar-a7k2000

    Personally I think this "chip inward" design is pretty stupid from an "air
    flow" perspective...

    My case has excellent airflow and now this harddisk won't benefit from that
    ?!?

    So the "chips inward" designs seems really stupid to me...

    What do you guys think of it ?

    Drives should always be handled with care so I think placing the chips on
    the inside is a bit over the top... ?!?

    Perhaps "gates" would have been better... like a little protective fence
    over it... but not inwards ?!? That's seems real stupid..

    Then again maybe gates won't work and perhaps inwards creates little
    turbulence for airflow towards cpu... but I rather have my harddisks
    properly
    cooled...

    I am hoping that this is not an issue...

    What you guys think of this ? Bad or not ?

    The drive does come with 5 year warranty... (from hitahchi, the webstore
    where I plan to buy it gives 3 year warrenty)

    Also what are these switches on the circuit board near the top center ?
    (really weird looking to me)
    (Or those switches at all or something else ?)

    http://www.storagereview.com/images/Hitachi-7k3000-PCB.jpg

    I hope I don't have to use those because I would not like to open it like
    that... with fluffy stuff
    coming out of it and all... could be a bit to get back in there ;)

    The price is excellent though... I can just get one for 103 euro's ?!

    And I need it bad I guess... running out of space for my Dream PC 2006 ! ;)
    =D (which had 2x500 GB ;))

    I'll probably order two just in case... they still available so gotta profit
    from that for future ! ;) =D

    Just want to know what you guys think of it... and I want to let the world
    know that this chip inward designs worries me a bit...

    Only adventage I can see is that it might collect less dust... and perhaps
    dust could create shortcircuits... or perhaps airflow/wind
    could cause static eletricity build up... so maybe inward better for that...
    but I am worried that heat will creap into the platter and might cause it to
    expand and shrink which could be bad... then again it's not like a cd with
    pits that fold back... it's just magnetics... so it's probably ok. (Maybe
    electronic head inside it might get heat damag ???)

    Just for the record the exact model is:

    Hitachi HDS723020BLA642 (Bulk, SATA 600, Deskstar 7K3000, 24/7)

    I also saw this site, claiming that it has surge-sensitive board:

    http://www.salvagedata.com/hard-drive/hitachi-ibm-data-recovery/deskstar-7k3000-hds723020bla642/

    But they seem to do this for each model/version of hitachi:

    http://www.salvagedata.com/hard-drive/hitachi-ibm-data-recovery/

    So I think it's pretty much a scare-off/scam site, trying to create fear...

    I am not going to let that site scare me...

    So far my previous deskstars are still working ;) =D


    One last thing which is a bit weird is this document I came across:

    To me it seems a bit sloppy, it mentions "Windows XP x64 SP3 ?!?!?!?!?!"

    As far as I know Service Pack 3 for Windows XP x64 edition doesn't exists
    ?!?!?!?

    http://www.hitachigst.com/tech/tech...0/$file/Deskstar_7K3000_CompatGuide_final.pdf

    Also seeing all these compatibility chips/host controllers makes me a bit
    doubtfull ?!?!?

    Will the 2 TB version work with my Asus A8N32-SLI motherboard ?!?

    I assume SATA600 is backwards compatible with SATA300 which is what Asus
    A8N32-SLI deluxe motherboard uses (!?)
    (I just checked and apperently it should be backwards compatible, so
    probably no issue there ?)


    So I am going to wait a bit with ordering... a few hours or so... to be able
    to see your guys responses if any... so I could reconsider if there is
    anything else to worry about or to look into closely... but I do hope to
    order about two before tomorrow... so that they could arrive tomorrow that
    would be great.


    (I should probably check some pictures of my build to see how many cables I
    need to pull loose from the stickies... but whatever I need to pull loose
    I'll do it... and place new sticky tape... because I want more gigabyte
    space... 2 terrabyte is about 1.9 terrabyte for real... so that's about 4
    extra TB with just 2 harddisks... that would be so sweet... wow... a bit
    over the top.. since my current space is just 1 TB lol... but still
    awesome... 5x times what I have now in total ! ;) =DDDDDDD



    Bye,
    Skybuck.

  2. According to this dude, he uses this board with 1.5 TB drives and he has no
    problem (with linux):

    http://vip.asus.com/forum/view.aspx...e&id=20090821181850250&page=1&SLanguage=en-us

    So this is a good sign... there is a high probability that at least this
    board will work with 2 TB drives...

    However if Windows XP x64 Pro supports it might be a different matter but
    for now I will assume it will work... since it's 64 bit for cry-sakes ! LOL
    ;) =D

    Even if drives get recgonized as 500 GB it would still be worth it for me...
    but I will assume it will be recgonized as 2 TB each that would be nice ! ;)
    =D

    Bye,
    Skybuck.

  3. Chipset drivers could also be an issue for 2 TB drives...

    Fortunately I have windows XP which doesn't seem to have these issue's...

    However Vista users might be in trouble:

    This is information from competitor seagate but it still applies:

    http://seagate.custkb.com/seagate/crm/selfservice/search.jsp?DocId=211211&NewLang=en

    http://seagate.custkb.com/seagate/crm/selfservice/search.jsp?DocId=206391&NewLang=en

    It's kinda funny, this is another confirmation that vista is kinda crap ! ;)
    LOL.

    I have Windows XP x64 Pro and as far as I can remember NForce4-sli chipset
    so fingers crossed ! ;) =D

    Bye,
    Skybuck.

  4. Ok,

    I just ordered these two hitachi drives... I am quite nervous that somebody
    might snatch them away and that they then go out of stock...

    It will probably be ok on the technical front... if anybody has any
    objections I might still be able to cancel them...

    And it's just 218 euro's or so with delivery costs included... so it's not
    like a big financial deal or anything...

    It's been a while since I ordered some new hardware and worked on my PC so I
    am quite excited ! ;) =D

    I can have a lot of fun with 4 TB I am pretty sure about that ! ;) =D

    First thing I am gonna do is extract 3DS Max 11 and then see if I can get
    mental iray working or something and see the photons in action... and then
    later I try FumeFX for some nice explosions ;) =D I know 3DS Max kinda
    boring... but I still wanna try it ;) Sigh and then later more fun to be had
    with video editing/recording that'd be cool too ! ;) =D

    And this way I don't have to clean up my other drives and squaze every last
    bit of gigabyte out of it... you know... that's just time consuming... this
    way I safe time too... which is real nice. No need to compress video's for a
    while. There are just a few... so that can wait till later... compressing
    videos sucks... it takes quite long really ;) I should do that... but I am
    too lazy for it ! ;) =D

    And now I go eat ! Being excited and hungry and nervous is strange ! LOL.

    Bye,
    Skybuck ;) =D

    A "chip inward" design, provides mechanical protection for the components
    on the printed circuit board.

    *******

    In terms of array sizes, doing a RAID 0 with two 1.5TB drives, gives a
    3TB total array size, which is larger than the 2.2TB (32 bit sector address)
    based limit with MBR. This would be an issue for "booting" from the array. Above
    2.2TB, you have to switch to GPT, and you don't have an EFI or UEFI BIOS.

    http://en.wikipedia.org/wiki/GUID_Partition_Table

    If you connect a *single* drive to the computer, I would not expect a problem.
    A single 2TB drive is less than the 2.2TB limit, and should behave like smaller
    capacity drives. You could connect four single 2TB drives, and each would be
    under the 2.2TB limit. It's when you build a RAID array with capacity larger
    than 2.2TB that there can be an issue, and as far as I know, you can still
    store data on it in that case.

    If the NV driver caused a problem, you can also test the SIL3132 port.
    So you have two chips to try, if you install a new disk. You'd need to
    make sure a SIL3132 driver was present in that case.

    *******

    Hitachi's disk division (formerly IBM), was recently bought by Western Digital.
    So their brand name may not be around for much longer. Warranty support
    may eventually be through Western Digital.

    http://www.hitachigst.com/press-roo...o-acquire-hitachi-global-storage-technologies

    Seagate recently bought some portion of Samsung's disk division.

    http://www.seagate.com/ww/v/index.j...toid=d00a78162ab6f210VgnVCM1000001a48090aRCRD

    Soon, there will only be Toshiba, Seagate, and Western Digital. And
    it makes you wonder how long Toshiba will last.

  7. The two harddisks have arrived on the day that william and katie (catetherin
    ?) married ! ;) =D
    (29 april 2011, 2 days after order day 27 april 2011)

    Kinda cool.

    I wish/hope my harddisks will bring me as much luck and fun as their
    marriage LOL ! ;) =D

    (You two are going to have a good marriage right ? ;))

    Bye,
    Bye,
    Skybuck ! ;) =D

  8. I think that well meaning but fundamentally uninformed rank amateurs
    need to start learning to trust the engineers that have the training
    and expertise to be able to make well founded decisions about these
    matters. Then we may finally see an end to all those gamer cases
    that look the part, and have far more fans than are actually required,
    but still end up with suboptimal cooling.

    The circuit board is going to be pretty insignficant in terms of
    heat output - I'd be surpised if it is drawing much over 50mW in
    total. Placing the chips inside the drive ensures that they are
    in a known environment as opposed to slap bang aginst another drive
    or power supply of unknown thermal output. The fact that components
    are protected is another benefit. This isn't a new arrangment -
    drive manufacturers have been doing it for years.

    Why do those expert, well trained engineers keep choosing burnout-
    prone Smooth motor/head controller chips? Are they nostalgic for 20M
    Seagate drives with Motorola MC3479 drivers that also burned out?

  11. Designing a controller board that only fails _after_ the mechanical
    side seems pretty smart to me. They can fail from time to time
    but it is almost always the result of prior mechanical failure.
    Damaged heads and/or platters cause the problem but are hidden out
    of sight inside the unit. The motor/voice coil controller (it
    doesn't talk to the head at all) is not so hidden, so it gets the
    flak even when it is the innocent party. If you drop your hard
    drive and it breaks that isn't the fault of the circuit board
    designer.

    I don't know the track record of drives with Smooth chips and have
    personally encountered only 2 failed ones, but those drives ran
    normally after chip replacement. I used to change MC3479 chips
    regularly in those Seagates (I once ordered 74), and the stepper
    motors were never bad.

    I want to retrieve my file as it was accidentally deleted. I am from Fort Lauderdale, FL. Can someone recommend to a shop that offers this kind of services? I need a verified one. Thank you.
