Hi all,
Long time lurker here, first time posting.
I have a crucial m4 ssd that recently died on me. I'm pretty much a beginner at troubleshooting this kind of hardware so I figured I'd take a shot and see if any of you all out there could help me out.
The symptoms:
-Drive does not show up in BIOS
-POST takes a very long time when ssd is connected to mobo, as if it is detecting something
Some things I've already figured out
The 5V rail does seem to be ok as all the different outputs from the LTC3545 regulator are at their correct voltages
All 0 ohm resistors jumping to the SATA connections measure <0.1ohm, so no problem there
I'm not sure what the pad labeled "5VF" means, but when the drive is powered on it jumps to 5V for about 2-3 seconds, and then drops to a few hundred millivolts. During this time there is also a high pitched screeching sound that is heard, like a CRT might make.
I'm curious if the behavior of that rail is normal, and I was curious to know if anyone could identify the components that I point out in the picture, marked AV1 and CC and what their role might play.
I have another one of these drives on the way so I'll probably crack that one open to compare voltages etc.
Any help is appreciated, thanks guys
