I installed W-XP on a PATA drive, then 'upgraded' to W-7 on a SATA drive. Unfortunately it seems to have installed part of W-7 on the PATA drive so I can't remove it. I adjusted the partitions on the PATA and all partitions on the SATA apart from the first vanished. They are visible in "Disk Management" but when I try to access one it says: "The operation failed to complete because the Disk Management console view is not up-to-date ..." Rebooting does not help. Can someone recommend a recovery utility?
