Micron RealSSD C400 no power

[TerraNova]

Hi Guys
I have a Micron RealSSD C400 , it has no power at all, anyone worked on this before? i think it uses electronic fuse ? Any feedback much appreciated, thanks.

Check 0 ohm resistors first

All have continuity mr_spokk

... it has no power at all ...

What exactly do you mean? Which voltages have you measured?

I did various test points on pcb, ex. 1v5, 3v3 etc all are showing the correct values. Marvel chip is dead cold

I suspect that the controller and SDRAM would require 1.0V, 1.5V and perhaps 2.5V, while the NAND array would run off 3.3V/3.3V or 3.3V/1.8V. The serial flash might be a 3.3V or 2.5V device. If all these voltages are present at their respective test points, then the board is correctly powered.

I would measure the 5VF test point adjacent to the supervisor IC.

Next I would confirm whether the crystal is oscillating.

The following thread may be of some help to you.

Have you tried to communicate with the SSD in diagnostic or "safe" mode?

Checking on it, thanks Frank

FYI, the SDRAM in the other thread is a 1.5V part, and the serial flash memory is a 3.3V part.

The NAND flash (MT29F128G08CFAAB, Micron) is an "L74A" part.

The following thread suggests that the 5VF test point should rise to 2.5V at power-on and then drop to 0V when the supplies stabilise.

If 5VF is sitting at 0V, my next suspect would be the D250x crystal.

More info on the NAND, for completeness.

I notice that, in the user forums, there is a potential remedy for a "no detect" symptom. Crucial advises the user to keep the drive powered for 20 minutes, during which time the firmware attempts to repair itself. Then the user is advised to power-cycle the SSD and check whether it comes ready. If not, then the procedure is to be repeated.

Not working, thanks

Hi,

I have exactly the same symptom!! All voltages measured right. Bios does not recognize it, but if I use an USB to sata adapter, I can read the Smart information and I can even flash the firmware. But if I try to initialize the disk, I get the cyclic redundancy check error. The chips are very cold too. The drive only have about 700hrs.

Any information would be great.
