HP SAS DRIVE [EG0300FBDBR] - NEED ADVICE

[chen_hdd]

I have a 8 disks array server, 3 disks are spinning ok and detected on PC3000 SAS,
but there are 5 disks that are not powering at all. I do not think PCB issue since all of the 5 disk are same model and same behavior.

I did research some article mention about disable pin3 SATA power for power disable feature. I did that still no luck.

Just hoping anyone has similar experience and have some tips to share or any hided feature for these type of SAS HDD.

Thanks

Do they spin up in the server? If not, is it possible that they could all have been clobbered by the same bad power supply?

The original server is fail, I have tried on new server, new NAS RACK they are not spinning at all
It just odd to me that the others 3 that working are different modal, but these 5 model are the same issue.
I wonder could it be possible that pin3 need 3.3v power to enter/exit power disable mode instead of not giving power to that pin?

Pin #3 should not be connected.

Can you upload a photo of both sides of one of the PCBs?
