Hard drive bays 3&4 painfully slow performance (3mb/sec) under Windows XP

I have the 2009 Mac Pro and experiencing ridiculously slow throughput of hard drives in bays 3&4. The drives are brand new Western Digital 1TB and Seagate 1.5TB, formatted NTFS. The drives work blazing fast when installed in Bay 2 (~90mb/sec!) but slow down to a crawl when installed in bays 3&4 (3mb/sec!). I used HDTach to run some low level benchmarks to make sure it's not an OS issue, and both the average read and burst speeds were 3.0 MB/sec. Under Leopard, the drives perform great. All of this leads me to believe this is some sort of Boot Camp driver issue that affects only the third and fourth drive bays/SATA ports on the new Mac Pros.
Any help is much appreciated!

Run WD Diagnostic on the drives and do a full zero and extended test on them.
I've had two WDs that had really bad I/O graph patterns showing jumps from 95MB/sec down to really slow and the long jaggie graph. I even put it all into a folder with charts and numbers.
XP has some real problems though with heavy small I/O patterns. Odd that it would change or show up different in different slots.

    *Update 10/2009:*
    I have upgraded my Mac Pro to Snow Leopard and installed the latest Boot Camp 3.0 drivers onto the Windows XP partition, hoping and praying that the above issue has been resolved. NO SUCH LUCK. Come on Apple, part of the reason I switched to Intel Macs was so I could have dual-OS support which is critical in my line work. Since 2006 when I bought my first iMac, then another iMac, then 2 MacBook Pros, I have never had such a horrible experience as now. Please Apple, do not shun your customer base who uses Windows!!

    logicboard.
    I have no trouble with bays 3&4 in Windows Vista/7 - never used XP so have no idea what problems it might pose.
    How about trying Win7 next?

  • MacPro Hard Drive Bays

    Hi Everyone. Here's a hard-drive question. Does a high performance drive perform differently depending on which bay it is installed in? Thanks, David

    Hi David,
    simply said NO.
    All four bays and the corresponding SATA port have the same max. throughput of up to 3Gbps.
    Have a look at the block diagram here: http://developer.apple.com/documentation/HardwareDrivers/Conceptual/MacPro_0608/Articles/M43_0906_arch.html#//appleref/doc/uid/TP40004479

  • Thinkpad Serial ATA Hard Drive Bay Adapter

    I would like to install a second hard drive in my T61. I saw a thread that advised I can do this by purchasing a "Thinkpad Serial ATA Hard Drive Bay Adapter". The thread also had a link where one can be purchased. However, the page displayed by the link said that the product was unavailable. Do I have any other options for installing a second hard drive? Will this adapter become available for purchase in the future? I want to install solaris or Linux on the second drive and boot from it, I assume this is possible. Thanks.

    according to the Lenovo website, yes it is the right model for the T61.

  • T430s 2nd Hard Drive Bay Caddy not working

    Hi all,
    I bought 2nd Hard Drive Bay Caddy for my T430s but it does not seem to work.
    The HDDs I placed in it do not even start to spin, and they are not recognized by the laptop BIOS as also by my OSes, Windows and Linux.
    The label on the caddy says it is P/N 26r9247, but at this stage I'm not sure is a compatible part or if I got just a faulty item.
    Any feedback?
    Solved!

    That part number (26R9247) is for the older T60/61 Thinkpads.  You need the Ultrabay III adapter.  Look at 43N3412.

  • Ejecting problem on my 2nd SATA Hard Drive Bay Caddy

    I am having an ejecting problem with my caddy secondary HD.
    Basically every time I close the lid, the secondary HD is ejected or, in case ejecting fails, I obtain an error message..very annoying situation.
    How can windows 7 avoid to eject it? Do you know a best practice to configure properly the 2nd SATA Hard Drive Bay Caddy??
    Thanks in advance!

    anyway Thanks!!

  • Can my macbook 4, 1 handle a 2tb hard drive if it fits into the hard drive bay?

    Can my macbook 4, 1 handle a 2tb hard drive if it fits into the hard drive bay?
    Does the hard drive brand matter as lon as the har drive fits in the slot?
    I want to put a 2tb hard drive in my macbook 4, 1 but I am not sure if the hard drive will work.
    Can my computer handle that big of a hard drive?

    "If it fits" will be the limiting factor. The largest capacity that I know of that will fit is 1.5 TB.
    OWC sold this 1 TB 12.5 mm WD hard disk a while ago that allegedly fit your MacBook4,1 so it stands to reason you won't be limited to a 9.5 mm dimension. The only 2 TB drives that I know of are 15 mm thick and will definitely not fit your MacBook. If and when you can find a 2 TB HDD in the required form factor it will work.

  • Installing SSD in hard drive bay

    I'm want to put an SSD in the hard drive bay of my W530 but am concerned about size and the rubber rails that came with the original hard drive.  The hard drive thats in there now is a 7mm drive, and I think the SSD I'm looking at is about 9mm high.  Is it possible to get different rubber rails to accomodate a taller drive (9mm vs 7mm)?
    Also, second, the drive I'm looking at is the Samsung EVO 500 GB SSD, which it says it measures 2.75" wide.  Will this fit or do I need to look for another drive?  I thought laptop drives were only 2.5" wide, but Samsung claims it's for a laptop.

    I swapped out the 512GB SATA spinner in my W530 for a 512GB Samsung 840 Pro SSD.  Fit perfectly using the existing rubber rails.
    Just be careful about the orientation of the rubber rails as they attach to the SSD.  I don't know if I consciously or unconsciously reversed them (from how they'd been placed on the original SATA spinner), but my initial install had them apparently backwards.  I hadn't noticed the two different pictures in the Hardware Maintenance Manual, and this is my first laptop and thus my first hardware change in a laptop.
    And even after I did see the two different drive pictures in the manual (which apparently were trying to convey a difference in positioning of the rubber rails) it really wasn't clear to me what they were trying to say.
    Anyway, my first "install" had the rails either upside-down or inside-out or something, but the drive itself ended up being RAISED above the power/data connector inside the drive bay cavity.  So although I though I had pushed the drive in firmly and could reattach the plastic bay cover holding the drive down, I had actually made ZERO electrical connection with the drive as it was a few millimeters raised from where it should have been and had obviously just slid right over the connector in the bay.
    After booting failed to recognize the presence of any drive, I removed it entirely and re-visited the two pictures.  I then realized that the rails had a proper "orientation", and maybe they were trying to show a DIFFERENCE in how you used the rails depending on whether you had a spinner hard drive or SSD.
    So I just reversed the rails, suddenly realizing that it had just LOWERED the drive a bit when inserted into the bay.  And NOW sure enough pushing the drive into the bay definitely felt like I was making contact with the power/data connector inside.
    And now sure enough the next boot discovered the SSD present and I was finally off and running.
    Don't forget to make use of Samsung Magician software, to optimize use of the SSD with Windows (Win7 Pro x64 in my W530).

  • How to replace hard drive bay fan?

    The fan in my G5 tower dual 1.8 Ghz in the top bay - optical/hard drive bay - has started to make noise. I bought a replacement, but I don't see any way to get the old one out. It sits in a little depression in the bay floor, and even if I got out the 3 screws holding it in place, it won't tilt far enough front or back to slide out.
    Anyone know of any write-up anywhere about how to replace this fan assembly?

    Those two fans (media bay fans) are only given a mention in the "official" service manual.
    The drive fan and blower located between the optical and hard drives cannot be
    replaced. You must replace the enclosure for these two parts.
    Does this mean the "entire" enclosure, as in the tower, or just an enclosure for the fans held to the tray of the media bay?
    I don't know.
    Maybe someone who has done this can offer advice, but it seems that there is a need for someone to write a manual for that procedure.

  • Dual Hard drive bays

    What are the models that have dual hard drive bays support (256 GB SSD + 500 GB HDD) ?
    Need following as well
    15.6 Display (minimum)
    16 GB RAM

    Hi,
    Please try DV7, Envy 17 .....  series of laptop, they have 2 HDD bays. Normally only 17" class laptops have physical room for 2 HDD's. You have to check the CTO (Config To Order) models, you may be able to config before buy. Unfortunately CTO models are only available in the US or may be Canada. Otherwise you can buy one of normal machine and upgrade later.

  • Does the G71-340 US Notebook Have TWO Hard Drive Bays

    My mother has the laptop mentioned in this subject line. She's got all kinds of issues going on with it. Runs slowly. Hangs. Shuts off randomly. I've run every virus scan and malware scan known to man and it's found nothing. It's either something that's on the hard drive that just isn't being detected and the only solution is to reformat the drive and reinstall everything from scratch or it's a hardware issue. I'm thinking of installing an SSD as the primary drive for speed improvement and reformatting the original drive that's in there right now and installing that as a secondary drive, *IF* this laptop has the ability to house 2 hard drives. Anyone know the answer to this 2nd hard drive bay question off the top of their head for this specific laptop? Thanks in advance.
    This question was solved.
    View Solution.

    Unfortunately this is not one of the models with the extra hard disk bay. So the answer is no. Consider an external usb hard disk or a NAS.
    Installing an SSD as a replacement for the original hard disk is the way to go. Use the largest that you can afford and run a factory image recovery from the recovery disk set.
    Take a look at the Maintainence & Service guide.

  • Z87 GA45 Gaming isn't recognising hard drive bays

    To starts, my set up specs are;
    Mobo - Z87 GA45 Gaming (brand new)
    CPU - i5 4670k (brand new)
    Ram - 8GB Gskill 1600, 8GB Geil Cobra 1600
    Storage- 2TB Seagate 7200rpm HDD, 250GB Samsung EVO SSD
    Case - LianLi Tyr PCX2000
    I bought the i5 second hand, but still unused a few weeks ago at a very good price, but of course needed a new mobo to accomodate it, since I was using an older GAX58-UD4P with an i7 920.
    Hooked it all up, everything seems to be working apart from the hard drives. The case has 6 hard drive bays that are hot swappable, although I never move them. I have connected the HDD to the power supply and to the mobo correctly. The HDD is spinning up on start up, so it's getting power. However the mobo doesn't recognise that theyre even plugged in.
    My cables all work, I plugged into the HDD directly and it recognised straight away with the same cables. I've also tried multiple hard drive bays, all to no avail.
    It was suggest I turn on AHCI in the bios, this was already on however. I did put it on IDE mode (no idea what it is tbh) and it did recognise one of the HDD, although it couldn't read any data off it.
    Any ideas on what could be wrong?

    Quote from: Sea Dog on 24-July-14, 15:26:12
    Test outside the case on a piece of plain cardboard or untreated wood then.
    It's working fine with it outside the case. Didn't even need to wipe the OS, and it's in AHCI mode. The bays worked perfectly on my old mobo, that was only in my case yesterday....I doubt all 6 have broken in this amount of time.
    I'll try and download some updates for the mobo and try again. Are there any old drivers for the Gigabyte mobo that could be causing conflicts that should be deleted?
    EDIT-
    I have updated the mobo with everyone on the MSI updater list, it however has made no difference. I have formatted the SSD and cloned my OS partition to it, it works fine when plugged directly in, however same as before, is not detected when plugged into the hot swap hard drive bay

  • I'm installing windows 7 64-bit on my imac which I've done before but I get a message that the partition is GPT even after I format the bootcamp partition.  I just upgraded my hard drive to a 3tb and I'm allocating 1tb for windows. How can I fix this?

    I'm installing windows 7 64-bit on my imac which I've done before but I get a message that the partition is GPT even after I format the bootcamp partition.  I just upgraded my hard drive to a 3tb and I'm allocating 1tb for windows. How can I fix this?

    No easy fix for a few reasons:
    1) Bootcamp requires a hybrid MBR for the partition table. That is: both an MBR and a GPT partition table at the same time with the GPT one having all partitions and the MBR one having only the ones that are relevant, but at most 4 of them (including the protective partition and the Macintosh HD one). Which leads us to:
    2) The MBR part of the hybrid partition table cannot work with 3TB hard drives. MBR is limited to 2TB.
    I am working on a small EFI app that can boot Windows in EFI mode on a Mac and that would mean that you can go GPT only on your system. The progress of the app is slow due to the nature of EFI and for now requires that you do an unattended Windows install with slipstreamed graphics drivers, but we are adding VGA loading on top of EFI quite soon after the rest of the app stabilises. The status of the app is documented at:
    Win7 x64 booting natively via EFI (no bios emulation)
    Windows does actually successfully boot in EFI mode on most Macs (anything with a 64bit EFI should work), but does not have graphics support even if you load the driver due to the VGA pci registers not being set by the firmware. Furthermore, in Setup and Safe Mode, Windows uses VGA instead of GOP which is a failure by design since VGA is a BIOS standard and not really compatible without hacks with EFI. Other EFI implementations also add VGA compatibility at a high cost to the firmware complexity for the VGA cards available on the market that don't actually contain anything in their ROM except the VGA BIOS.
    My recomendations:
    1) Install on a second smaller hard-drive; or
    2) Wait for the EFI app to come out officially and use that to boot Windows Vista SP1 x64 and Windows 7 x64 (RTM and SP1) in the native EFI mode.
    3) Wait for Windows 8 which supports VGA-less booting acording to the AMD presentation at UEFI Plugfest.

  • HT1351 I recently had my hard drive wiped out by a virus and had to reinstall windows and itunes. When i hooked up my ipod it didnt automatically sync my songs on my ipod with the library. How do I do this manually?

    I recently had my hard drive wiped out by a virus and had to reinstall windows and itunes. When I hooked up my ipod it did not transfer my songs from my ipod to my itunes library. How do I do this?

    iTunes syncing is generally in one direction only, from the computer's iTunes library to the iPod.  You cannot use iTunes to transfer song files from iPod to computer (except for songs purchsed from the iTunes Store).
    However, there are third-party methods and utilities that can transfer from iPod to computer.  If you do an Internet search on something like "ipod transfer," you should get some links.  (The CNET article seems to be popular.)
    Once the song files are on your computer's drive, you can add them to your new iTunes library.  (Going forward, you should use a backup strategy, and include your iTunes data in what gets backed up.  Then, you would be able to recover your complete iTunes library, including things like playlists and ratings.)
