Greetings.

I am trying to get these working again. Data on these is not important. Hotswap or current damage.

One is a Patriot Burst 120gb and the other is a TEAMGROUP GX1 120gb.

I can't seem to find out what the SOT23-5 chips are. On one they said 578BR on the other 578BW. I am assuming DC-DC converter but no idea.

Middle pin on 3 leg side is ground.

Awesome. Thank you.

I have another sdd. ADATA SU650. Similar SOT23-5 marked [3102] also shorted, possibly the same?

I found your PCB Protection Devices posts on another site and it helped me get two Kingston's going. Electronic fuses were open.

Thank you for that too good sir.

It has the wrong pin count, but ...

... it would appear that the pinout for "3102" is ...

1 = Pgood or Enable
2 = Ground
3 = Lx
4 = Vin
5 = Feedback

Since the 16-pin IC is made by M3Tek, I'm wondering whether "3102" is a special 5-pin version of the MT3102.
