Do HDDs have many electrolytics? Those are the main culprits for going bad, and are usually used for power electronics, not controllers/processing circuitry (they don't need the bulk capacitance that you'd usually use an electrolytic for)
- dougg3 2y agoThere are indeed some aluminum electrolytics hiding on Quantum drives. They look sneakily like tantalum caps, but they're just cans hiding inside a plastic cover. Here's one where I accidentally broke the cover, revealing what's underneath: https://i.imgur.com/LdjUx3v.jpeg https://i.imgur.com/LdjUx3v.jpeg
- ComputerGuru 2y agoYou can’t convince me that’s not intentionally disguised like that.
- yborg 2y agoIt's more likely so these could be used with a pick and place machine. They're obviously lytics if you look at the ends. I don't know why everything has to be a conspiracy these days.
- mystified5016 2y agoNo reasonable EE would mistake this for anything but an electrolytic cap. This is a very old package design from the transition between through hole and SMD. The process for making the vertical axial style common now hadn't been perfected and it was briefly cheaper to cast regular axial caps into an epoxy block. No other component looks like this, it's a very distinct package and footprint from any other type of cap. No one tried to disguise anything, they really just thought this was the cheapest way to make a surface mount electrolytic cap.
- Panzer04 2y agoThat is cute as hell XD
- doctor_radium 2y agoI'd have to pull the drive to have a good look, but my memory is that the circuit board resembles the inside of a 1960's era transistor radio. Will hope you're right.
