I have a Crucial M4 SATA 512GB SSD which has failed. It's a few years old but was new, only used a few hours. I was using it with a usb 3.0 enclosure as an external backup drive when suddenly it stopped working in the middle of a video I was watching. The usb to sata adapter works as I've used it with other drives. The drive now makes a small ticking noise as soon as it is plugged in, kind of like it's trying to fire up but it can't. Twice it worked for me for short while after I opened and cleaned it with alcohol but now refuses to just clicks. I'm thinking one of the ICs is fried or a bad cap?

Crucial M4 SSD failure?

Re: Crucial M4 SSD failure?
Hi.
1) love love love ethiopian veg food
2) the ssd is solid state but it was making these noises? Perhaps could be the power supply region and may be the switching power supply components like the coil?
Anything look like it is burnt? Perhaps you can post some pictures of the internals?
Suggest to try the ssd with another known good enclosure.

Try a new cable, they are very fragile. Then look at the connector on the USB enclosure board. Not the SSD drive.

Re: Crucial M4 SSD failure?
I wonder if a MLCC capcitor has shorted? The clicking would be one of the buck-converters trying to power up into a short circuit.
I would try to power up the board and you can measure the power supply voltages at the top-side square testpoints. See there are 3V3, 2V5, 1V5, 1V0 voltages to look at. There should be 5V coming in for main power.
If a cap is bad, hopefully it gets hot so you can find it.

The coil on bottom gets 1.1-1.3v and it outputs.1.52v
The coil top right gets 1.0v and outputs 0.70v
The coil top left directly above bottom coil gets 2.14v outputs 2.52v
The biggest coil gets 3.37v and outputs 3.30v
Is the IC in-between these coils ok? I am also getting 3 caps with low resistance (100 ohm) and 132 diode mode on the back of the board behind the ic.

1V5 = 1.53v
ATP = 0.60v
5VF = 0.00v
1V0 = 1.01v
2V5 = 2.52v
3V3 = 3.37vLast edited by SuperAman; 02-19-2021, 09:25 AM.

Re: Crucial M4 SSD failure?
Sorry was a little busy and put this on hold. I had determined the 5v was missing. Also the 3 tiny caps I removed, couldn't find them. Lot of useful info on this site. I just found it, will investigate further. https://forum.hddguru.com/viewtopic.php?f=10&t=29757Last edited by SuperAman; 03-15-2021, 12:22 PM.
