Hello everyone. After a long search for this drive on the forum to replace the TVS diode i cant find anything.

In this pcb is not very clear and the letters/numbers on the components not resolve anything at all after looking for it on google.

Can anyone help me to find the TVS diode? I dont know if this drive have one or two (+5 and +12). In other topics ive seen, a temporal (and risky) solution to turn on the hdd, is unsolder the bad tvs diode. That is exactly what i need, to make a quick copy on other drive. This will work?

Thanks and sorry for my english.

Hi Copemcor,

What makes you assume it's the TVS? Does it shut off the computer power supply when you plug it in?

Yes, i've tried 4 different mobo and when i plug the hdd, the system dont do anything, stays completely dead.

Thanks a lot prasadsv. Do you recomend me to unsolder the bad tvs to make a quick copy? Very risky? Will it work?

First Check the diodes with multimeter
You Have checked with 4 PCB ?
Same complaint ?
Some time it may happens with power supply also

I mean 4 differents computers with differenet power suply

Then proceed checking diodes

I am not quite sure about it. If you find the way to solve it, just tell me.
