WD5000SY damaged driver board

[mehdis]

Hello,

I had this external HDD and the power brick was blown. So I purchased a new power brick with the exact same part number from EBAY. It looked exactly the same, only the GND and 5V pins were backwards on this brick! So the HDD was damaged. I opened the box and it has a WD5000SY. I removed the driver board and noticed that the switching DC/DC components on the board were blown. There is a ST L6284 chip that looks intact, but I feel that one is gone too. Because I check on of the output voltage rails and it is shorted to GND. I hope every thing else is OK, because there is one regulator that still creates 3V3. So now I just want to recover the data. I was thinking to create those two power voltages created by the DC/DC externally and make the board run and take the data out. But I don't know what voltage they were generating. So, any idea there?

Also I couldn't find the datasheet of L6284 anywhere. Does anyone have it available? Thanks guys for any help.

Why build a car when you can hire cab? You're making it 10X harder than it needs to be.

Find a drive with the same PCB and start there.

That's one way too, but it's cheaper for me to power up the board without the on board power supply rather than buying a HDD and damage it! From the previous posts I also see that it might not be possible to run the HDD with a board taken from another similar HDD as SW adjustments could be different. Thanks.
