My wife's Windows XP computer has a 20GB HDD that is formatted with NTFS. I would like to add an 80GB HDD and, instead of adding it as a separate drive in Windows XP, edit the already-present partition to include the 80GB HDD. This would use two drives, but create a C:\ drive of about 100GB. I remember something about NTFS partitions being editable, but I can't remember what it was. I may just be thinking about the ability of a FAT32 partition to be changed to NTFS without losing any data. Is there any software out there that will allow me to add these drives together under one partition, preferably while maintaining the data on the current 20GB drive as it is? I may even be getting into some sort of RAID configuration, or perhaps I need to do something with virtual drives. Its been a long time since the last time I tried to set something like this up.

Do not proceed with this plan. If ( When ) one of the drives fails you will lose all data. Add the extra drive , assign it a drive letter and use it for storage. Goin' Fishin' (Some day)

Clone the 20GB HDD to the 80GB HDD...once you're sure it's working properly, format the 20GB drive & use THAT one for storage.
