Andy:
I assume that you did not install SP1 when you originally installed Windows
XP. The actual capacity of your 200 GB hard drive is about 186 GB (in binary
terms). The 189 GB your BIOS is reporting is close enough. I note you state
Windows XP reports the capacity of your HD as 127 GB. I'm not sure if that's
a typo since the OS should be reporting 137 GB, assuming you installed XP
without SP1.

Assuming, as you state, that the mainboard's BIOS supports large-capacity
drives, i.e., drives greater than 137 GB, the Windows XP OS (not including
SP1) will recognize a maximum capacity of 137 GB so that the maximum
partition one can create will be that size. Should the drive have a greater
capacity, the remaining disk space will not be recognized by the operating
system. If, however, the XP installation disk includes SP1, then the full
capacity of the disk will be recognized.

Again, assuming the mainboard's BIOS supports large-capacity drives, when
SP1 is subsequently installed, the full capacity of that drive greater than
137 GB will be recognized -- the 137 GB that was partitioned/formatted when
XP (less SP1) was installed; the remaining GB will be shown as "unallocated
space" -- space that you can subsequently partition/format using XP's Disk
Management utility. But note that it will be a second partition on the disk.
The only way to create a single 200 GB (actually, about 186 GB) partition on
that disk in this situation would be through Partition Magic or similar
program.

You do not need, nor, in my opinion, should you use the Maxtor Big Drive
Enabler software patch under the conditions that I've indicated above, i.e.,
your BIOS supports large-capacity disks and your XP OS includes SP1. These
so-called "overlay" programs seem to cause more user grief than they should
over the long-term. They seem certain to rise up and "bite" you at some
future date when, should the need arise, you have to repartition/reformat
your drive.
