Re: SD card trouble

I already tried all of those things. Replacement is the last place i'd want to go. Why is that? What is so terrible about replacing a micro SD card? If your card is dead (undetectable or read-only locked) then that's the only place you have to go. Unless your 3B is actually a 3B+ or you have set th...

Re: SD card trouble

Try formatting it in a digital camera or phone. Or make another Raspbian card for your Pi and see if it can detect the problem card (in a USB reader). If so, try erasing or overwriting it with dd. If you zero-fill the first 4K of the card you should be able to format it (that wipes the partition tab...

Re: Pi4 Cooling

Mine is currently cooled by a quiet Noctua 40mm 5V fan in an open sided case with no heatsink. In my experience, a fan works better than a heatsink alone (which only postpones the inevitable throttling). Fan and heatsink together will run cooler, but with a fan the heatsink is unnecessary.

Re: Pi3 - USB boot

When the system is booted with no SD card it takes an extra 5 seconds, because that's how long this system checks for an SD card. With an SD card in the system (even a non-bootable one) the delay is shorter and boot starts faster (unless you're using bootcode.bin with timeout).
