Toshiba THNSN2256GSPS totally dead

[PijoMax]

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

I would measure V1 - V4.

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

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

he said PCI card, not SATA

I have the exact same problem on the same drive. You say to check V1-V4, what should they be normally?

I don't know their actual values, but I know they shouldn't be 0V.
