I did some searching/reading before posting and I think it might be the TVS's on the PCB. I was out of town and had a really bad lightning storm. The drive is recognized (sort of) in Vista, not in XP. In neither situation were the contents displayed to the computer (in XP it recognized that something was connected but 'hardware not working correctly' was displayed).
It was a MyBook, I took it out of the MyBook case and put it in a new external dock. The drive spins up normally, and makes no clicking sounds, after about 10-15 seconds it stops spinning, and starts all over again, this repeats indefinitely. I am fairly certain it is PCB related (after reading on here I am guessing TVSs).
In the attached a picture:
D2 reads as described on the threads (open one way, 57 ohms the other)
D1 reads 122 and 51 (so I suspect this one is bad).
D3 reads 405 and open
D4 reads 520 and open

What else should I test, any recommendations? What other information would be useful?

PCB: 2061-701477-000 AB
MDL: WD5000AAJS-32TKA0
Date: 15 DEC 2006
DCM: HBRCNV2AB
LBA 976663168

I talked through email with a "sunnydreamspace@hotmail.com" offering to sell a new PCB. From what I gather (from reading on here), for newer drives that is relatively unlikely to fix it. Any idea if he is legit?


Also attached is the pad, which shows some marks. I am unsure if those are normally there, or are the result of the short.

Hi,

If you are lucky, only the MCU (read channel side) is damaged with the internal (programmed) unique adaptive info.
But more chance for preamp and/or heads are dead.

This case is clearly for a pro, seek for help, if your data is important, there is nothing what you can do.

Thanks for the info. I have no problem going to a pro, but before I do, do you think there is much risk of a problem if I pull off that bad TVS and try it that way before sending it in to get fixed? Or does the fact that it spins up imply that all the TVSs are fine?

Its not TVS. Only a pro can fix this.
