目前已知具有此类的硬盘型号为:WD80EMAZ、WD100EZAZ

此经验来源于油管。

不能识别的原因可能如下(来源于西部数据官网):

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.

用中文表达的意思就是:

SATA3.1及更早版本标准,硬盘的供电接口1-3pin是3.3v供电,很多硬盘是空着不接的(但是这款以及同款8TB的白色标签款西部数据硬盘没有取消1-3pin)

而对于支持SATA3.3标准的设备,这个3.3v的供电反而会阻止硬盘正常启动。

很多电脑主板只支持SATA3.1标准,那3.3v会一直供电,就造成了这个硬盘不能启动。

解决的方案有两个:

一是把供电接口第3pin屏蔽掉:使用透明胶把这个接口贴起来,为了拍照显眼一点我用白色不干胶贴起来示意。

第二种方案是使用4pin转sata供电的转接线转接,这样转接后的sata供电口是不带3.3v供电的。
