this is very strange. I have two laptops. A Toshiba portege 7020 that had a 2GB Active partition and a 4GB NTFS partition with a clean install. In Disk management under Storage, when I right-click Disk0, there was NO option to upgrade to dynamic disk. My other laptop, a Tecra 9000 with 10GB partition and a clean install, when I right-clicked on Disk0, came up with "Upgrade to dynamic disk". I re-formatted the disk on the Portege to a single active partition and re-installed W2K. STILL no option to upgrade to dynamic disk. Any thoughts as to why both systems should be different?
