I have 2 SATA hard disks, Vista Home Edition on one, XP SP2 on the other. I used DDS to partition both disks. Vista partition 1 contains the OS and apps and partition 2 my data; same setup on the XP disk. Acronis DDS sees all the partitions and their contents and so does XP's Explorer. However Vista's Explorer cannot see the 'my data' partitions on either disk - it sees the partitions as unavailable. Any ideas?
