I am a complete newcomer to DD10 and purchased it on the recommendation of PC Pro magazine who have just put it on their A List. Try as I might however, I cannot get it to either create a new partition or split the existing partition. When I try to create a partition, I get the message 'Invalid Partition Size' on boot up. When I try to split, it goes through a painstakingly long disk analysis, asks me to reboot, then after going through its process returns me to the desktop with no error message and no split. I have a 250gb Maxtor SATA drive, with Windows XP Home. It is a RAID drive with a small recovery partition applied by MESH. Anyone any ideas please?
