I would confirm that +5V is present at the input and output of U21 (MP5001DQ). Also measure the voltages at inductors L1 - L5.

I meant L1 to L5, ie L1, L2, L3, L4 and L5. |

Those voltages look OK (they are similar to those in another SF-2281 thread). You might want to check the terminal port. Look for something like this (SF-1222TA3-SBH) ... Quote: CLI> PINRST

There is no terminal port on this drive. I did experiment and found the short points to get the drive into safe mode. However as its SandForce it doesn't really help. Many thanks for the help as always. |

The following thread discusses an Adata S510 which is based on a SandForce SF-2281VB1-SDC controller. The voltages are the same as yours. https://www.eevblog.com/forum/repair/ssd-recovery-(adata-s510-128gb)/ Quote: At least something is alive - by shorting J3 (as mentioned in https://geektimes.ru/post/263876/) I can activate the "developer mode" which appears in Device manager as "mass storage device". Also hooked my USB-UART dongle to J4 TX pin and found out that the firmware doesn't load properly.

Now I have safe mode activated (called developer mode in that post) I can see that the FW is not loading in PC3K. Would be nice if Ace Labs can get this one sorted one day. |

Maybe I'm too cynical, but ISTM that, instead of admitting that they can't do it, Ace are saying that it's not worth doing: http://forum.acelaboratory.com/viewtopic.php?t=9443 |

It would be a big feather in their cap if they can do it, so I am sure they are doing their best but yes, it has been about 4 years in development and perhaps its time to move on. Luckily the SandForce controller is not so popular now so might be out of circulation in the next few years. |
