I have a Seagate Free Agent GoFlex USB External Drive 1TB. The drive just stopped working. It is not being picked up under "My Computer" or "Disk Management" when connected to Windows Laptop or Desktops. I can see the device under the "Disk Drives" section of Computer Management. The drive is also lighting up and spinning, but making a clicking sound. Please let me know how much it would cost to recover the 1TB of data. I suspect it?s the PCB, as the logic board is not responding."
