I have a OptiPlex GX1 pc which sees 127GB of a 180 GB drive. If it reads 127GB, it's likely it would read 180GB, since they are both "large drives". I think.
Nope, Dell GX1 won't go higher than 120Gbyte disks (actually 137 Gbytes or so, depending on how you define a Gbyte..). Actual max capacity is 512 * 2 ^ 28 bytes.

The drive enabler would enable large drive support, but the GX1 onboard IDE controller still will not be able to use more than 137GB. Like suggested buy a PCI IDE controller and attach the drive to that (or use a 120Gb or smaller drive).
The fix was to just type 1 in the DWORD Editor [regedt.exe] and it worked perfect! Microsoft website never addressed what to do if you could not type the "x" in 1x0.
IF YOU ENABLE 48 BIT LBA in the registry and the bios doesnt support it you will get corruption and eventually 100 percent data loss once data starts going over teh 127 gig area.
Warning Data corruption may occur if either of the following conditions is true
:• You use this registry value to enable 48-bit LBA support in the original release version of Windows XP Home Edition or of Windows XP Professional. • You install an earlier version of Windows on a disk partition that was previously created by a 48-bit aware operating system, such as Windows XP SP1. And that disk partition is equal to or larger than the current addressable limit of 137 GB.
Note The previous registry setting is ignored in Windows XP SP1 and later. If you try to enable the 48-bit LBA ATAPI support in the original release version of Windows XP Home Edition or of Windows XP Professional by editing the previous registry setting, and you did not meet the minimum requirements, the following issues may occur:
• The registry value EnableBigLba is disabled. If you have a 48-bit compatible BIOS that can support a hard disk that has a capacity that is greater than 137 GB, only the first 137 GB of the hard disk are addressable. The rest of the hard disk is not used. • The registry value EnableBigLba is enabled, but you do not have a 48-bit LBA compatible BIOS and the capacity of the hard disk is not greater than 137 GB.
If you enable the 48-bit LBA ATAPI support by editing the registry setting, but you lack both a 48-bit LBA compatible BIOS and a hard disk that has a capacity that is see comment than 137 GB, you have not changed the system. The hard disk continues to function as a standard hard disk. • The registry value EnableBigLba is enabled without a 48-bit LBA compatible BIOS, but you have a hard disk with a capacity that is larger than 137 GB.
If you enable 48-bit ATAPI support in the registry and you have a hard disk that has a capacity that is see comment than 137 GB, but you do not have a 48-bit LBA compatible BIOS, only the first 137 GB of the hard disk are addressable. The remainder of the hard disk is not used.

You seem to be ignoring an important point.
