HDD GURU FORUMS

This SSD has no status register lights showing in PC3K. So I am hoping it's an electrical problem rather than controller. The board is receiving power. Most readings are 3.3v or 0.6v. Can someone give me some specific test points for me to check to try to find out where the issue is. Any help would be much appreciated.

I suspect that your adapter may not support the DEVSLP pin.

You certainly out in a lot of work in the previous post. That was quite an epic job.

I shorted the F1 pin as suggested at the end of the post and get the same error as Adisa. The SSD just shows 2mb. The is not 2mb of data but 2mb of junk. So I may have the same FW isses as Adisa, but I think shorting F1 has other effects. In a flash drive a signature like 2mb usually indicated controller failure, so could shorting these pins be affecting the controller doing it job?

"F1" is simply a fuse for the main power supply. It just bypasses the DEVSLP circuitry. ISTM that you have a "firmware" fault.

Okay thanks.
