Just browsing here, but it sounds like a simple fix. I would have to look it up in my references because I don't yet have XP on my computers, but here is the XP procedure as I remember it. I don't believe that XP comes with fdisk, and if you are not familiar with hard drive architecture and file systems, it may be worth reading up on. They are really not that complicated. In order to use fdisk(FAT16 and FAT32 drives only) you would need to be familiar with how to run programs from a command prompt. Fdisk is very simple to use, but you will have choices to make that you need to understand before proceeding. The main differences between FAT32 and NTFS are 1. NTFS uses smaller cluster sizes, which wastes less disk space when files do not use the whole cluster. 2. NTFS supports the advanced file level security features offered by the NT-based operating systems, ie. NT/2000/XP. If you are running XP, I would recommend using NTFS. Sorry about the rant, now the solution.
Someone correct me if I am wrong, but I don't think that a system that boots to a FAT32 drive can access a disk that is formatted NTFS. The fix should be easy. If you can boot XP on the FAT 32 drive, you just right click on My Computer, select Manage, and go to the disk management applet. In there you can convert a drive from FAT32 to NTFS without reformatting or repartitioning. You should also be able to format and manage partitions on the new 20G drive once you convert the old one.
Hope this helps.
