Top of PSU - the insulation on the inductor is not paper

Bottom of PSU

This is a PSU from a Infrant/Netgear ReadyNAS NV+ system. The PSU likely failed because of design problems instead of faulty components; the failure seems to be a common event on certain manufacturing batches.

Notable features on upper picture: 3 bulged capacitors, 1 inductor with burned insulation. Notable features on lower picture: signs of overheating, jumper wire in solder.

These pictures are of a Maxtor model 6V250F0 250GB 7200RPM hard drive. The owner noticed a burning smell from the drive after which it was unplugged. Upon being powered up, the diode was destroyed. A similar diode was removed from a Samsung model SP1614C 160GB hard drive and soldered onto this board to successfully repair it. Credit: THE_GFR
