How to identify a genuine unit
Genuine 400-ATKQ units feature a Dell enterprise drive label displaying DP/N 0H8D3F, 300GB capacity, 15000 rpm rotational speed, and Seagate model markings ST300MP0006. In iDRAC under Physical Disks, the 400-ATKQ registers with certified Dell firmware, active SMART diagnostics, and spindle temperature monitoring. The DXD9H (14G–16G) carrier for 400-ATKQ includes status and activity indicator light pipes.
Buying used
When evaluating a pre-owned 400-ATKQ, check SMART logs via OpenManage or smartctl to verify zero reallocated sectors (attribute 0x05) and zero pending defects (attribute 0xC5). Check power-on hours and execute an extended drive self-test on the 400-ATKQ to verify smooth bearing rotation without head-parking noise. Ensure the correct DXD9H (14G–16G) caddy is supplied with the 400-ATKQ.
