As per the subject line, I have connected my 2TB WD Elements HD to a 19v laptop PSU by mistake and the drive has blown. I have read about the diodes and resistors that can blow but I am unsure which they are on this drive. I have worked in electronics service for most of my life but have never dealt with hard disks.
The drive is dead, and even when plugged directly into a caddy without the input board attached it is dead. Are there any components on the input board that may have gone or is it more likely to be the main board attached to the HD?
Any pointers would be gratefully accepted.
