TVS Diode location on Toshiba Canvio PCB G3448A

[Perl_tester]

Hi,

I have a power dead Toshiba Canvio 1TB external drive and was hoping someone could point out the location on the PCB of the TVS diode (fuse) so I could short it and get my data back.

Here is the PCB reference

Any help is appreciated

Thanks

Pat.

Take some measurements first.

BTW, a TVS diode is not a fuse.

Many thanks,

I've just come across hddparts and will use their service.

You know a board swap won't work

Yes thanks but they will also transfer IC602 for me, I will send them the old board.

This model drive rarely has PCB problems. Are you sure it is a PCB problem? Many people just assume it is.

+1, +1, +1 to this. USB native drives very rarely ever have PCB issues. 99.9% chance the issue is internal. Probably bad heads, G-List damage, etc.

Sorry lads, but read my OP its power dead. The LED doesn't light when connected so its deffo a pcb issue.

We read OPs all the time and more than 90% of the time it is not a PCB issue despite people saying the "drive is dead". A drive being dead is a very vague statement.

Does the drive spin up when connecting to computer?

Well, the drive is a USB model (as per the OP), so it derives its power from the USB port ...

Thanks all, and sorry for not getting back sooner.

To finish the story it was a dead PCB in the end. I shipped the old USB3 PCB to the guys in hdd-parts.com. DHL from the Netherlands to Canada cost 75 Euros and took 5 working days. Jason at hdd-parts.com was very helpful and for 50 dollars Canadian provided a replacement SATA PCB AND transferred the bios chip from the old board to the new. Then 30 dollars Canadian to ship it back the the Netherlands which was OVERNIGHT (DHL could learn a thing or two from https://www.purolator.com). I put the new PCB on the platter and hooked it up to my PC and was delighted to see it come alive! Immediately performing a backup to the NAS!!!

Thats it. Again thanks to the forums here for pointing me in the right direction and very happy with the outcome.

Pat.

Thanks for the feedback. Your experience demonstrates the value of measurements. ;-|

For all that money in parts and shipping hiring somebody local and support the local economy would have been a better choice. It is just a matter of communicating clearly what you expect from the service.
But happy ending is always good either way.
