This thread makes me feel incredibly old. Not just because apparently IDE cables are something that people today don’t even recognize, but I actually have the exact same style hard drive with a burnt fuse that also holds ~0.4 BTC on it. A strange coincidence I guess. One of these days I should fix mine too.
I'm guessing that when a HDD ended up with a burnt fuse the disk won't spin anymore or it won't receive power, that fuse must have blew to protect the drive I bet, what were you doing before that event took place?
It might not be that easy to get it fixed if it's a shorted related outcome, like you breached components together? Hope you understand what I am trying to say, I have 10s of HDD with, some are dead and I have experience with HDD very well.
You will need multimeter to figure out which diodes are dead, this is the very first thing to look out for, avoid going for the fuse as if nothing happened,fuse don't just blew up for no reason on HDDs.
Hope you are good with soldering iron too, good luck
Well, it was back around 2012-2014 I think. I had just received a shipment of ASIC miners and was using every bit of power I could find as minutes were crucial at that point in time (for a very short period, maybe a week, I think I had the highest hashrate of any individual in the world). I connected an ASIC to a power supply that was operating a computer as it had enough spare power to power it. Unfortunately miners back then aren’t what they are now and it caused a bit of an explosion that took out my hard drive. I’ll probably bring it into a shop at some point, but for now I like to pretend that the wallet is a gold mine holding far more BTC than I actually think. It is more fun that way.
