Remove TVS Diode on WD 4TB Black

[gibson]

This problem has been resolved. The middle fuse/resistor pointed out by F_ARG was indeed blown. A local electronics repair shop was able to replace it and drive is working perfectly now.

Thanks a billion to F_ARG and others who took the time to answer. These things are always stressful and it's a relief to be done with it.

I also want to say that while I have seen negative reviews of Donor Drives/Outsource Data Recovery on here, they could not have been more helpful in discussing the problem with me by phone. Had I not found someone local to make the repair, I would have sent the drives to them.

Also wanted to add that I did find another new WD 4TB Black hard drive with the same PCB. However we did not have to use it as a donor board as the repair shop was able to simply replace the blown fuse.

Well done, fortunately "luck" was on your side this time, always a good thing ( and nothing wrong with that, we all wish for it )

Hey all,

sorry to resurrect this thread but I'm facing the exact same problem with the same dead fuse. (exact same drive)

In the right black circle there's a dead fuse (I tested it with a multimeter):



I have no idea if someone in my area will be able to replace something that tiny and delicate.
Is this a normal common fuse or should I ask for something specific?
Can I buy the fuse online and just look for someone with a matching solder iron? (Mine is way to thick for this) What should I look for?

Thanks!

Sometimes a fuse blows due to a problem in the plate and changing it can cause the plate to end up breaking when it is broken in another more delicate place.

I recommend that before connecting the board the insula of the disk is not going to be that occasions a more serious problems in the reading heads.

@Shasoosh, did you measure the 5V TVS diode?

[Shasoosh]

@mhp666 My PSU fried my motherboard and took the harddrive with it. I'm pretty sure that's the reason the fuse is blown.

@fzabkar I've measured everything in the picture above. The right black circle fuse is the only one that's problematic. I'd like to replace it but can't identify with what fuse I need to replace it. I tried searching for that pcb schematics with no luck.

Look for a 2A smt fuse at places like Farnell, Digikey, Mouser, RS Components.

Thanks @fzabkar

Does the v matters?

https://www.ebay.com/itm/10-Pcs-Littelf ... m570.l1313 is good for example?

[fzabkar]

The voltage rating is OK. Good luck.

Thanks. Last question, should I get fast acting or slow blow?
(sorry, I'm really clueless with this)
