New 8TB ,HDD installed: continuing error "internal disk needs repair"
I've replaced the failed 3TB HDD(SATA 6Gb/s 64MB Cache ) with a model number (ST3000DM001) in my TC (A1470) with a 8TB HDD (from HGST model no HUH728080ALN600). I've used the Airport Utility to try and set it up but keep getting the error "internal disk needs repair". I've tried soft, hard and factory default resets, but neither Finder or Disk Utility 'sees' the TC.The OS on my iMac is 10.10.4.
The Wireless connection works fine .
The speeds are the same for both the HDD's.
The detailed specifications of the HGST drive is as below:
DRIVE PERFORMANCE :
INTERFACE TRANSFER RATE : 600 MBPS
SUSTAINED TRANSFER RATE : 205 MBPS
SEEK TIME (READ, TYPICAL) : 8.5 MS
AVERAGE LATENCY : 4.16 MS
BUFFER : 128 MB
ROTATIONAL SPEED : 7200 RPM
