Lost space on HDD

  Pillo 13:55 16 Feb 2006

I'm building a system with a Sempron 3400(64), 1GB Memory (DDR400) and 160GB SATA Maxtor. I am currently formatting the HDD prior to loading WinXP Pro. Can anyone tell me why the Windows setup only sees 131GB available on the HDD??

Some motherboards are only capable of seeing 132GB, this can generally be fixed by flashing the BIOS.

should how as 152617 MB (approx)

have you got SP2?

Shows 137G not 160G or Higher
In Windows, click on Start->Run, enter "regedit".
# Navigate to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\atapi\Parameters registry subkey.
# From the Edit menu, select New, DWORD Value.
# Enter the name EnableBigLba, then press Enter.
# Double-click the new value, set it to 1, then click OK.
# Close the registry editor.
# Restart the machine for the change to take effect.

If I could do what you suggested I wouldn't have a problem. I'm formatting the drive as part of the WinXP setup so I haven't got Windows loaded yet! following Alan14's suggestion, for your info my MoBo is an Asrock K8NF4G SATAII so I would have thought it would have no problem with a 160GB HDD.F

With what are you formatting it?

I'm using the NTFS format option as part of the Windows XP Pro Installation Disk.

If you are using a disk that does not contain SP1 then it will not see above 132GB. Once the installation is complete and SP2 installed the full size of the disk will be apparent.

If what you say is correct, then you are spot on. I am using an old WinXP disk which is pre-SP1. I'll do as you suggest once the instalation is complete. Thanks to everyone who responded.
