"stop being a cocky ass"

As usual, when you cannot argue facts,? the weak argument becomes
personal.? Cool.

Just because someone eats 20 greasy hamburgers a day and lives to be 120 doesn't mean everyone will.? Computers work in absolutes, yes, but the issue becomes, if the hardware has an issue, the computer cannot always force it to perform as designed.? I had that issue with Engineers 30+ years ago.? They design a circuit, they have you assemble it, it doesn't properly work, both digital and analog.? What their book learning doesn't take into account is tolerances of components.? Tolerances stack up and now they are outside the "theoretical perfect world".? They don't see that, they argue and obviously whoever assembled it is the issue. Memory is the same way.? Bulk manufacturing isn't perfect, and the factory format may or may not have properly completed, and there may be an issue that keeps the system from properly accessing the device.? Unfortunately, I have seen it MANY times.? Windows is the least forgiving OS.? You stick a memory card in, or attach a drive, and some issues will make the disk subsystem put the device offline due to some access error.? At that point, even from a system utility, the drive cannot be written to or read from.? MacOS is probably the 2nd pickiest, and Linux the least.? Don't even get me started on DEC's VMS...

There are no absolutes in this field.? You probably have not yet had enough experience to learn that yet.? Keep learning, it will come.

That's why I say NOT to format the card before copying the image.? In most cases, I would say it doesn't make a difference, but I have seen some where it has.

Also on MacPro (yeah yeah I'm 25+ yrs *nix guy).? I dd'd the 1st SDCard (wiped block 0 & 100) and the PI imager did all the magic - so long story short - not really sure of the issue - but both 128Gb's running like a charm.? Now onto USB boot on Pi4....
