I have an esata dock and it works fine with my existing formatted sata drives. I purchased a new sata drive and plugged it in the docking station to format the drive and windows 7 cannot see it. I can take it out of the docking station and plug one of my old sata drives in and windows see's it immediately. How do I get the new one to be seen and format it?
Any brand new empty HDD needs two steps of preparation before an OS can use it. They are to Create a Partition on that drive, and then to Format that Partition. On current OS's, these two usually are combined into one process called Initializing the Drive.
