Thread: Hard drive size limitation due to BIOS?

  1. #1

    Hard drive size limitation due to BIOS?

    Hi there, I'm running Win XP and have installed and formatted a 200 gb hd, but after formatting it only shows 127 gb. I had a friend tell me I need to flash my BIOS, but I don't know how to do this, or what file(s) I need to download in order to do this. Could someone maybe provide a link to the appropriate file(s) with a brief description of how to go about flashing the BIOS. Much thanks, oh, and here's my bios and motherboard info:

    System BIOS : Award Software, Inc. ASUS A7V8X ACPI BIOS Revision 1013
    System Mainboard : ASUSTeK Computer INC. A7V8X
    System Chipset : ASUSTeK Computer Inc VT8377 Apollo KT400 CPU to PCI

    It's probably easier and less risky to just fit a PCI IDE controller card [they're so INEXPENSIVE].

    I fitted one, it provides practically unlimited HDD drive capacity, and it frees up the internal IDE controllers. So now each of my optical drives has their own controller and therefore all three drives [there's now capacity for four to do this] can run concurrently.
    No longer any of the business of having two drives on the same controller and attempting to read from one and write to the other so that they're forced to take turns; one reading, stop, the other writing, stop, first one reading again, stop, second writing again, stop,.... Ouch!

    So you see, you get very useful extra capability for very little cost with no risk of turning your motherboard into an ornament.

    I actually already have one, but when I format the drives that are connected to it it still only goes to 127 GB.

    BTW, I have Win XP SP 2.

    Here's some more info on my BIOS from this program called SiSoftware Sandra:

    "I actually already have one, but when I format the drives that are connected to it it still only goes to 127 GB"
    This sounds like the same problem I had and managed to fix.

    1. I bought a new larger Maxtor HDD and used their Maxblast program to set it up for use. That means it partitioned the drive and formatted the partitions, and a Dynamic Drive Overlay [DDO] was automatically installed because the m/b BIOS couldn't see all of the drive capacity.
    Now here is the REALLY IMPORTANT PART...
    Somehow, to make the BIOS see the drive, I had made the program get the HDD to MISREPORT ITS SIZE to the BIOS as being a size that was the same as the maximum that the BIOS could see, so now the on-board BIOS was happy.
    Now the HDD was reporting its size as much smaller than it really was, but a DDO had been installed so that the whole of the drive capacity could be used.

    2. Now I bought an IDE controller card and eliminated the DDO [by zero-filling the drive] and connected the drive to the new card.

    3. But the card's BIOS could only see the size that the HDD was now misreporting.

    4. In order to get the card's BIOS to see the full capacity of the HDD I had to Use the Maxblast program to "Change the drive size" back to its "Native Capacity" [the program correctly detected what that was, displayed it, I chose it, ok'd it].

    5. Now when I connected the drive to the new card the correct capacity was detected, I partitioned that capacity, formatted the partitions, and all was well.

    I think this is the thread with all the details...

    Mind you...
    As Deagle said...
    You still need Service Pack 2 of WinXP for windows to se the capacity above 128GB.
