I'm using Win7 ultimate 64bit. I've downloaded Partition Magic and now I can't see one of my partitions. If I try to change the partition's letter I get an error message: ''The operation failed to complete because the Disk Management console view is not up-to-date...). If I will go to Device Manager and I'll uninstall the driver of my hard disk all the data will be deleted? Sorry for my English. Please help me!
