Specs: Windows 7
right so i know that with win XP you need SP1 or above to use all the space a HDD bigger than 127GB's i think. so i had formatted my computer, installed a new 500GB HDD reinstalled XP, then SP3 and looked on the net to fix this problem, but couldn't do it for some reason. then i got win7 installed it and still have the same dam problem, i have tried all the partition programs but i still can't seem to get all 500GB's.

am i not understanding? doing something wrong or wat?

Does the correct size show in the BIOS? What does Administrative tools / disk management say?

disk management says its only 137GB and so does BIOS! do you think its coz i used the win 7 format thing on the installation page? (sorry does that even make sense?)

i was thinking although i am probably wrong that as i installed win XP first and that only creates a partition 137GB in size that when i installed over it with win 7 even using the format it still kept it that size?

its either that or my hard drive is only 137GB, which i have checked and the label says it 500GB so i am honestly just totally confused!!!

Look at this page. It lists all the tools needed for your manufacturer's hard drive.

There are TWO possible issues. Both relate to 48 bit LBA compliance. Both the motherboard BIOS and the OS (operating system) must be 48 bit LBA compliant.

As you noted the original release of WinXP was NOT. But you didn't identify weather or not your BIOS is 48 bit LBA compliant.

Now that you already have a hard drive larger than 127/137GB capacity installed it is easy to determine.

Simply watch the POST screens at start up to verify that the BIOS is identifying the drive by BOTH the model number and the FULL capacity.

If the BIOS show a capacity in the 127/137GB range then you need to install an add in controller card to use that 500GB drive.

If however it is identified properly then you just didn't delete the old partitions and create new ones.

um... i forgot to mention i am using a laptop, sorry i not sure if that makes a difference or not?

Yes it sure does make a difference. You can't add a controller card to a laptop.

Post the exact model of the laptop. It may be possible to get things working but not likely.

Why don't you check to see if there's a bios update for your laptop. Check the manufacturer's site.
