Would greatly appreciate any help the community can provide with the WD3200AAVS drive i managed to burn out by plugging in a 19V charger into its enclosure (it was part of a MyBook).
I’ve read through fzabkar’s very helpful guide on TVS diodes here: http://community.wd.com/t5/Desktop-Mobile-Drives/HDD-TVS-diode-FAQ/m-p/250274#M6826. It’s given me some reassurance that maybe my data is not completely fried after all… I’ve gone ahead and ordered a multimeter as well.
However, I’m having trouble identifying exactly which part is the TVS diode on the PCB. Nothing looks obviously scorched/burned, and none of the numbers seem to match the “common marking codes” listed in fzabkar’s FAQ.
Could anyone help me identify which diodes/resistors I should be testing with my multimeter (when it arrives on Friday) in the below photo?
Thanks very much to anyone who can help!
