I ran a few tests with the Hitachi GPT Disk manager and it has a lot of bugs: 1) An installation on Windows XP Professional (32bit) (with the Hitachi hard disk attached) is impossible. It says "HITACHI ultra-capacity hard drive is already correctly recognized" although that's impossible and the HDD is not listed in Disk Management of WinXP. 2) Installation on WinXP Home worked, but harddisks set up by Hitachi GPT Disk manager which were connected (during the set up) to an AHCI Sata Port are not correctly mounted when plugged to an IDE-mode Sata port (same computer, just different port). The HDDs _are_ recognized in the Hitachi GPT Disk manager, but instead of mounting them the Hitachi GPT Disk manager demands to set them up anew. 3) When I do it the other way around (set up a HDD on an IDE-mode Sata port and then plug it into an AHCI-mode SATA port) then Windows Home crashes, both during boot and during hot plugging. When I buy the GPT Loader from Paragon, will it have the same issues?
