Possibly shorted component on Seagate HDD

[lbwlow]

I got a Seagate SV35 series 320GB HDD with me that doesn't spin when connected to the power supply, however I noticed there one component was very hot to touch, what is the component for ? I have lookup google for the component but I can't seem to find any detail on the component. The component is circled in yellow which I have uploaded it.

Thanks in advance

Re: Possibly shorted component on Seagate HDD

least of your concerns, the inductor is broken - so is the one above it!

Yea, that because the other guy stack those HDD, might as well accidentally scraped off the housing of those inductors. But what the proper way of testing inductors? I have tested it with my DMM and it still has continuity.

they are probably bad - the lower one is anyway.
the ferrite case is part of it - if it's bigger or smaller it effects the inductance.

you test them wih an LCR meter or a component tester, but you need to know the value and it's usually printed on the top - that you dont have!

Ouch... I still remember i had a couple of those drive around last time before i scrap those. Got to dig into my junk pile again and hopefully can find one with the same PCB. But anyway, can a bad inductor without casing cause the component that I mentioned to become overheat and drive not spinning ?

yes that is a switching converter it supply's power to something and without that supply the controller will be in error or some other part has been damaged by the broken supply.

Thanks all, by replacing the broken inductor on the PCB, i get the HDD to spin again. But the HDD was bad and it was clicking. Despite that but i appreciate it and learned something new

No problem
