My external Maxtor hard disk had become a FAT 32 format & I need it to be NTFS. I've got this far: 1/Copied all my data to another source. 2/Deleted the existing partitions 3/Found the drive in Disk Management. 4/Right clicked on it & proceeded with the New Partition option then bottled out when it started on about primary, logical, unallocated etc.!
