Not completely. MS screwed it up. You will get data loss
if you use more than the first 128GB of the driove.

Have a Dell Dimension 8300 desktop. Just installed a Western Digital 160
gig hard drive without any problems. An issue is that the set up shows
the drive as 160 gig. However in Windows it shows it as a 126 gig.
What's with that?

After I installed it I went to "Control Panel", "Administrative Tools",
"Computer Management", "Disk Management". There it showed the drive as
126 gig. Of course I had to format it so I did.

So why is it shown as 126 and not 160?

To fully use drives larger than 127GB, you need 48-bit addressing. This
may not be implemented by your PC's BIOS. If you go into your BIOS setup,
can it see the full capacity of the drive?

It also must be enabled within windows. That comes with Windows 2000 SP4
and higher, or Windows XP SP2 and higher.
