I was actually very impressed. Just yank the restraining clip in the front
and the power supply comes right out. Swapping supplies took seconds.

The fuse near the AC input did blow but it appears to have blown too late.
There are multiple scorch marks all over the board. At least three
resistors no longer "resist" and one transistor seems dead also.

Now, why did the disk drive do that?
