樓主呢款hdd, 部份係支持SATA3.3標準. 如果電源不支持sata3.3,(實際係大部份都唔支持), 個sata供電部份Pin3有3.3v的話, 個hdd就可能無法啟動的.
我朋友送左一個俾我, 佢係從my book度拆出黎. 但係插在MB度用唔到, 送左畀我. 我上網查先知道呢個問題.

* SATA Specification Revision 3.1 and prior revisions assigned 3.3V to pins P1, P2 and P3. In addition, device plug pins P1, P2 and P3 were required to be bused together. In the standard configuration of this product, P3 is connected with P1 and P2 and this product behaves as SATA 3.1 or prior version product in a system designed to SATA 3.2 system that does not support the 3.3 feature. For product with the optional SATA 3.3 Power Disable Feature supported, P3 is now assigned as the POWER DISABLE CONTROL PIN. If P3 is driven HIGH (2.1V-3.6V max), power to the drive circuitry will be disabled. Drives with this optional feature WILL NOT POWER UP in systems designed to SATA Spec Revision 3.1 or earlier because P3 driven HIGH will prevent the drive from powering up.

樓主最好查清楚隻hdd係咪sata3.3先賣, 提醒一下買家.  唔係有人買左到時啟動唔到以為壞就麻煩.
