Question about Western Digital Caviar SE16 (WD5000AAKS) 500 GB SATA Hard Drive

3 Answers

Trying to format a 500GB HDD at full capacity

I purchased an internal WD SATAII 500GB HDD to expand my storage space. I bought an adapter attachment that fits on the back of the SATA drive so I can hook it up with PATA cable and power. No matter what I try, the OS only recognizes 137GB and wants me to make partitions or volumes of that size, whether as a Basic or Dynamic drive.
I have two other internal WD HDD's of 200GB which I had no problem formatting them as 200GB drives and also three external USB2 HDD's larger than 137GB that are recognized with no problem and formatted at their full sizes (300 and 320GB).
I would like to format this new WD SATA 500GB at full capacity and not four partitions or volumes of 116GB.
I have tried using Data Lifeguard Tools but it does the same thing.
I am running WinXP SP2. It is WD5000AAKS internal hard drive.
The drive is not initialized yet because I did not want to format at less than full capacity. So it does not show up in the My Computer drive tree. It does appear as Disk 3 in the Disk management box as an uninitialized unallocated drive at 128GB.
Do you have any suggestions?

    I already have HDD's (300GB & 320GB) that are recognized, so wouldn't it show that my BIOS is updated to recognize HD's larger than 137GB?

    I checked on the adapter and the specs say that the adapter accommodates 48bit LBA.

  • Sumdude Oct 12, 2007

        The adapter is JM20330 SATA or SATA 2 drive to IDE 40-pin Cable adapter.
        I purchased it from

    I agree. I am trying to do just that.

    Hi Have the same problem with adding a WD Caviar SE16 with ATA interface as drive 1 (D:), the drive is sometimes seen by the BIOS AS 500GB drive and sometimes as 'Not installed'. XP-SP2 does see it as a 500GB drive (467) but during convert to Dynamic complains that it not can write the information (after been busy for 3 hours)

    Also during convert (or format of a primary partition) the computer freezes almost totally.

    Tried it on 2 different systems with XP-SP2

I had this problem today!!! Turns out, some very early versions of XP don't have the LDA48 (or whatever the letters where) support, so it can't register anything bigger than 128GB (thats 131072M). It was my mates PC that i built, tried my version of XP and it recognised it fine, mines SP1 so i'm guessing this is very, very early versions....

Having said this XP dates back to 2001, its 6 years old now, how old is SATA?? Suppose back in 2001 60Gig was probably big, i can't remember to be perfectly honest..!

Sounds like the SATA - PATA converter doesn't accomodate for a 48 bit LBA (to handle disks of more than 137 GB)


you need to get the correct converter, as this one is not compatible, you should be able to return the converter as not fit for purpose (needs LBA 48bit).

    it might be worth buing a Serial ATA Controller


    like the Adaptec Serial ATA RAID 1210SA PCI card


    THis will support up to 2 drives and costs about £40


    oh yeah and has LBA 48bit

    erm how is that not helpful... I've told you what's wrong, the ad for the controller card even confirms it.

  • Gareth Cockram
    Gareth Cockram Oct 12, 2007

    Your bios does use a 48 bit LBA (so you can see your large HDDs, however the adapter you have to convert the disk is obviously the sticking point here.

  • Gareth Cockram
    Gareth Cockram Oct 12, 2007

    what model is it?


    obviously something is wrong otherwise your disk would be showing as 500Gb


    we know your mobo is fine as you are already using 320 GB disks,  it's unlikely to be the disk itself, so that only leaves the adapter


    perhaps there is a settings jumper on the adapter itself

    certainly looks right, can't explain why it's not working tho.. perhaps it would be best to give them a call to see if there is anything they can suggest.


    They should replace it,  and hopefully the replacement should work.

Check your bios if the disk is recognized as 500gb first. if it is not recognized, update your motherboard bios. most updates are available in their manufacturers site.

    If you are installing a hdd internally, The motherboard bios MUST recognized first what are the hardwares connected internally such as RAM, HDD,  CPU, etc. Connecting hdd externally or through usb is very easy because the OS is the one recognizing the hardware, even guides you what to do with it. P3 Mboards was not recognizing more than 4gb hdd, was corrected using EASY BIOS software installed during bootup (that was 80~90's's era where computers uses  a BIG 2GB hdd!!  Haha, it does not even fit the 4gb os mem of todays computers).

Will Dell Inspiron 530 support Sata iiI (SATA 3) SSD?

Unfortunately the motherboard of the Dell Inspiron 530 supports RAID 0 5 and the maximum speed will be 3Gb/s that means that the motherboard only supports SATAII. If you want to have a SATA III SSD you will need to change your motherboard.

Hi guys, i have a new WDbluecavier 500Gb,16Mb cache but the allocate space is how can locate the remaining space??

This is the real capacity of your 500 GB hard disk - they are measuring it incorrectly for commercial reasons (in reality it's just 488GB) and there is a part that is reserved internally. There is nothing else.

SATA to PATA adapter or...

I don't think you will find an adapter than will fit into a laptop - they isn't any space.
You will need to buy a SATA.
You can by and enclosure for PATA hard drive and make an external drive to back up your stuff (if you can't return it).

Can't detect HD WD 500GB SataII 16MB cache

If you purchased a full retail hard drive the drive came with Data Life Guard tools. Boot to the Data Life Guard cd and follow the prompts to set up your new drive. This should by pass any bios limitations.

If your drive didn't come with the Tool cd you can download it from Western Digital's site.
