Hi,

This is a seagate drive, and you have one short TVS diode.

[miekenos]

so whats a TVS diode? and are these common?

[miekenos]

it is a seagate barracuda 7200.9 so what size tvs should i be looking at and specs i should be after? Janus the man

[hddguy]

The TVS is quite easily identified because it is a rather large black component with just 2 contacts to the PCB, and is clearly seen damaged in your picture. Many HDDs have TVS diodes, I often have Samsung HDDs with damaged TVS, but pretty much any Seagate PCB will have a suitable power diode you could use.

But without the correct tools, you may only end up making things worse!

[miekenos]

im hooked up with the guy at work he has the tools however are these common like with sizes and power or are there an array of choices?

[hddguy]

If you post here a picture of the PCB from your 40GB Seagate PCB I can tell you if there is a component on there that can be used.

ok too the left of the screw im guessing is wat ill need but if not how do i know the specs?

[ccc]

that was the one i was thinking , im getting it sorted tomorrow so ill tell u how i went thanks bud

[miekenos]

ok tvs is replaced but no power up:( any help?

[jono-ats]

The TVS has a polarity. If you put it in backwards it will fail.

Just remove it altogether and see if drive powers up. Makes sure you have a good power supply as noted.

if its reversed the supply will not start after u plug in the hdd . does this happen when u plug hdd .
