So I just secure erased my Time Capsule disk through AirPort Utility to set it up with my new iMac. After erasing the 1TB disk, AirPort said that the disk capacity is only 931GB even though the Time Machine preferences displayed 998GB available prior to me initiating the first backup. Does anyone know why this discrepancy exists? It should be noted that the previous backup on the Time Capsule disk from my old Mac took up about 68GB so is AirPort Utility just struggling to show the new capacity after the secure erase? Please help!
