Hello,

I have a WD 3200SD Raid drive that burned a chip on the PCB on power on of my PC. The drive was 2 months old. It was the chip that controls the spindle motor and the drive wouldn't power on after that. I bought an identical drive with identical firmware, even the date of manufacturing was the same and swapped the EEPROM on the PCB's, then the swapped PCB's themselves. On power on it spun up, clicked twice then spun down. I then replaced the head stack with the assembly from the donor drive because it sounded like the preamplifier was dead (with a special comb tool I made - 6 heads!) and now on power on the drive spins up, clicks about 8 times before spinning down. I read the Head Stack Replacement article and it said that WD's don't start well after head replacement because the axis angle of the arm is set by the screw in the lid. Does anyone have experience with this to confirm that it is head stack misalignment? I would appreciate any advice that anyone may have. Thank you.

hey guys, im in an similiar situation. Its a wd400eb. I did a head and pcb replacement. SADLY the drive spins and make a couple of 'click of death' shows. After 2 mins or so the drive turns off.
I tried to do the screwdriver 'in the axis' thing but didnt get it...
Could you develop this part a bit more guys?
thanks and respect.
aniba!
