Repair of Plextor SSD PCB

[RGB255_0_0]

Brilliant job.

Sorted, soldered a test lead into the removed inductor and powered at 1.2 V. The current drawn is 0.6 A. Connected this supply first and then the SATA connector and power. Drive took around 10-20 seconds and then bingo, detected in my windows PC.

I was able to recover all of my critical data. My main objective is now complete. I may still try and repair the drive fully as a hobby, but will not really ever use it for anything important or critical.

Thanks all for your assistance! I would be nowhere close to retrieving my data without you!

 

Good to know it worked and you're welcome.
Given the power consumption of less than 1 W, I'd say that in this case, it was only the regulator that had failed.

I just noticed the datecode 1425 on the pcb and wondered if the warranty has expired...

Probably not. But they wouldn't have repaired the SSD but just replaced --> bye bye data.

Nice job walking through this repair. It will be informative for anyone who faces a similar issue in the future.

I guess you will have a hard time to find what IC it was. However you can try to find some pin compatible DC/DC converter IC (with synchronous rectifier) in DFN-6 package. Feedback resistors might need adjustment for proper output voltage, but repair is completely doable.

You may be right, but the point was now that the data has been retrieved, there's no need repairing it yourself if it's still covered by warranty (unless of course the famous "warranty void" sticker has been broken).
