				I have an IBM Deskstar IDE Drive.
 
Model: IC35L060AVV207-0 
 
P/N: 07N9212
 
MLC: H69205
 
Made In: Thailand
 
 
PCB:
 
07N9226
 
H69056
 
 
The drive sustained an electrical surge from a recent storm.  Oscillogram shows a short spike on the 12V at the beginning but flat lines after that.  The 5V shows a steady 115 mA.  Obviously I have a PCB problem.

I assume the best course of action is to replace the PCB and move the Adaptive SMD.  Can someone confirm that U5 is the correct and only chip that needs to be swapped to the donor PCB?

When matching the PCB for an IBM Deskstar, are the numbers below the only ones I need to be concerned with for a match?

Any other thoughts would be most appreciated. |

				U5 (93LC66) is what is commonly referred to as the "NVRAM". This chip needs to be transferred to your donor. If the boards are not a perfect match, then I expect that U6 may need to be transferred as well, but I'm not a data recovery professional.
 
 
My HDD IC database may help you identify the components:
