Question about HP Compaq d530 PC Desktop

2 Answers

Does my d530 CMT have a SATA connector?

My d530 CMT came with a 40 GB Maxtor DiamondMax Plus 8 ATA/133 HDD, which I'm told is an IDE drive. What's puzzling is that I've got two different types of plugs on the same cable supplying power to the HDD. A total of 6 white plugs labelled P1 through P6 that have the 4 wire setup. And 2 black plugs on the same cable attached to nothing, labelled P4-1 and P5-1. These two black plugs have a narrow multiple strand socket, like a small serial plug.
(1) Are the black power plugs used for SATA drives?
(2) Does this mean my d530 supports SATA drives that are faster than the ATA/133 variety?
(3) what kind of SATA socket on the mobo should I look for?
(4) Geesch - anyone have a diagram of a d530 mobo?
Thanks again guys,

    Thanks! But I've scoured this website and HP's all afternoon trying to find a mobo diagram for the d530 - and can't. Does that mean that they used a zillion different boards from as many manufacturers? If you can find a diagram I'd be surprised - and indebted!

    Another poster sent me a document titled, "New Key Technologies and Features of HP Compaq Business Desktop d530 Series" from "HP Confidential" published in May 2003.

    "Although the 865G chipset does support SATA, HP engineering does not believe the entire solution [is] ready for mainstream corporate deployment. Essentially, the current maturity of the SATA subsystem (controller/driver/HDD) does not meet HP’s robustness and error recovery requirements and hence will not be made available until after the
    d530 launch. The HP d530 series products will be "SATA ready" at launch. A customer can purchase
    a third party SATA HDD and cable and expect some functionality. This allows customers to begin cursorary SATA testing."

    I suspect "some functionality" refers to the d530's SATA controller allowing speeds of only 150 bts/sec. roughly the same as the PATA/133 standard. To get the current SATA 300 drives to be recognized, jumpers have to be set to slow the speed to the 150 bts/sec the controller can handle, likely voiding the drive's warranty. As well as the hassel of updating the BIOS as you state.

    Although it would be neat to push this venerable old machine to it's limits by running a comparatively slow, first generation SATA drive, there would be little if any speed advantage. So in the end I decided to stick with a well tested WD Caviar 160 gb PATA/133 drive. I figure I'm saving myself the trouble of making BIOS changes I don't fully understand. Anyway, by the time I need a newer machine, 160 gb thumb drives might be out, putting the need for a SATA drive in question anyway!

    How would you rate my decision?

    This has been a real fascinating exercise.

    Thanks guys.

    Gary - thanks alot. Got the WD 160 gb PATA/133 yesterday - learned to set the jumper on both the master and new drive to "CS" (neat - so when it's time to switch the old C drive to slave and new one to master it's just a matter of swapping their position on the serial cord). Then I followed the easy steps to initialize and format the new drive. And bingo - worked flawlessly.

    Truthfully, I'm a little disappointed I don't have a SATA drive - but I didn't have any headaches either. And for what I do, the 2nd IDE drive will be adequate.

    Two new things though - what's a good, i.e. free, software that'll copy my operating system on the new drive? Someone posted that Seatools by Seagate had a good mirrowing function - I couldn't find that under "Tools" - but I did discover my old drive has 57,000+ hours of operation!

    And second, I've got a digital video card/error message issue - that's described in a new message.

    Thanks again for your interest in all this Gary. The level of expert help I'm getting here is hard to find anywhere.

Answers to your questions:
1. Yes
2. Very likely
3. a Google search should show you what the connectors look like.
4 HP/Compaq do a good job of providing documentation. Go to and put in your system information. You should be able to locate motherboard diagrams there. If you can't let me know and I'll try to locate them.

Hello Mark, the D530 CMT does support SATA drives. You can reference further details in these documents:

The SATA connector looks like this:

I can't recall if the plugs in the D530 are black, but you should be able to tell from the diagrams if they are the right ones (they won't fit otherwise). The older IDE style connectors for Ultra ATA are slower, so you'd definitely want to leverage SATA for better throughput.

    NOTE: On the power cables, you will see a SATA power connector. It is black
    and about half as thin as the standard 4 pin power connector. On the
    left side of the motherboard, you'll see a very small circular
    component with a yellow dot on it, labeled for "CPU Reset". On either
    side of this are the SATA motherboard connectors. The one on the left
    is slot "0", which is the one you would use.

    I can't find a motherboard diagram, but the components are well labeled--you should be able to find whatever you need. Here's a hardware reference document that may also help:

    Here's another hardware reference document. There isn't a motherboard diagram, but you really don't need one. You should be able to tell what is what, because everything is labeled. And you can always refer back to the manual for further information.

    Good information uncovering there, Mark. I didn't realize that SATA
    has had different supported controller speeds. But it does make sense,
    seeing the timing of SATA and the unveiling of the D530 CMT. You could
    of course buy a PCI SATA controller card, if indeed you wish to
    leverage the data throughput. However, if your needs are unlikely to
    push it, you made a good decision with the IDE drive.

    Later on, you can always acquire an external drive. I did and it
    performs extremely well. I use it for large media files and backups.

    Hi Mark,

    I'm glad to hear the new drive is working very well for you. :-)

    are a variety of solutions available to mirror an entire disk drive,
    sector by sector. Most are commercial and cost some $$. I've heard of
    one called EASEUS Disk Copy, that is free.
    I've not used it so I can't guarantee that it'll be fool proof. But
    when you're starting out with a completely new drive it can't hurt to
    give it a shot (if it doesn't work, just reformat and use something
    else like Symantec Utilities).

    Once I replace my PSU, I'm going
    to mount an existing 250Gb drive I have into my D530 CMT. This should
    hold me for a while... but if I decide to go for another drive, I may
    go with SATA. For just $20, you can buy a Rosewill SATA PCI controller
    card with one internal SATA connector and one external. Not a bad deal:

HDD Upgrade

That model has standard IDE interface for hard drive. Don't think 500 GB or higher comes with that interface. The standard now is SATA interface for hard drives. Here is a lnk to the owner's manual for you model:
You tell the difference between standard IDE and SATA in that the standard IDE interface uses a wide flat ribbon cable to connect to the drive. SATA uses a small thin cable as shon in the following link:

You cannot use a SATA (serial ATA HDD in this machine. You need a PATA (parallel ATA) HDD, also known as IDE, ULTRA IDE, ULTRA ATA. This has a 40-pin ribbon connector & a 4-pin power connector.
Sizes generally available would be 80GB up to 250GB, although very few PATA drives are now sold since SATA is the new standard.

What new HDD will match my Maxtor DiamondMax Plus 8?

You can use any size HDD in your computer as a slave and it does not have to be an exact match for the maxtor. You will however need the make sure that the connections on the new drive match. For example SATA drives will not attache to an IDE cable and vice versa. The drive that you mentioned is an IDE style drive so unless your MOBO has SATA connectors on it you will need to buy an IDE/EIDE drive.

The drive you have is a IDE, Ultra DMA 133, 4200 RPM.

If you are running XP or Vista you can purchase any brand hard drive. Recommend Maxtor. Just make sure it is IDE and for a desktop.

Hope this helps.
