Hi Sirs, I received this SSD. Connected to adapter (PCI card) no signals of life. Completely dead, not recognised at all. I double checked the adapter with another SSD, adapter it's ok. Electrical issue (if yes where to check) or Controller issue? Thanks in advance Max

Did you ever find the cause for the SDD failure? I see the recommended test points, but not the specs for voltage. I have an identical drive which seems dead too. It just gets hot. I can't see any physical damage to it. Thanks for any information pierre |

AFAICT, THNSN2256GSPS is a PCIe SSD. If so, then it won't work with a SATA adapter. Is that your problem? |

You say to check V1-V4, what should they be normally? |
