Smith:... did you follow the link I gave you above?
When you were in the XP setup screen, you had the options like we spoke about to make partitions, well after you made your 28gb partition C:\ you had the option then to hit the "C" key and create a partition on the "unpartitioned" space left on C:\.....got it? Thus why you don't see it in "my comp". If you had done it correctly you would have seen D:\.
*Did you format using NTFS or FAT32? doesen't matter unless you are dual booting with and older OS and XP..and its not why you are having problems.
So you can do two things well....err...maybe three things. If you don't get you touchpad problem sorted out. I would start over again and reinstall XP "clean" Or you could boot using the XP Cd again and partition the unused space on C:\. Although you would have to "quit" the install of XP after, since is automated, and be quick about it...lol. Last use FDISK to partition the unused space on C:\. Also ...lol when in doubt "READ" you manual on the proper install order of the drivers for XP off the driver CD. Its important to install them in the proper order, starting with the chipset drivers and for the correct OS. The driver CD may contain folders for more than one OS.
PS the best way to learn this S*%t is to build your own desktop from parts
