Burn ISO Image to Micro SD Card

This is 100% irrelevant just like some people reporting they never had trouble with Win32DiskImager or dd!

 

It's about the average user and expectations. And the average user runs Windows for whatever reasons and has no clue about Windows being crippled by design when it's about handling removable media and 'foreign' filesystems.

 

And the average user also has the naive assumption that burning to SD cards always works, that crappy/counterfeit SD cards do not exist and that 'transmission problems' caused by card readers or USB ports also do not exist. That's why it's so important to ONLY RECOMMEND ETCHER all the time.

 

Completely agree...

 

Etcher does a great job - and the verification ensures that one has a good write to the card...

 

When in doubt - one can use the SDCard Formatter Util (Win/Mac) to "refresh" the card prior to writing...

If it fails, then check either the card, or the reader...

Files are often corrupted or not burned properly many times.

 

sounds exactly what people want... :thumbup:

 

or Method 1: Burn ISO Image to USB Drive with WizISO?

which doesn't mention disk verification anywhere? Doesn't make sense too.

I used for a longer time not Samsung ProEndurance SD cards and the quality looks a lot higher. Not even 1 Samsung card is broken instead of a few Sandisk cards... :) I read on another Raspi forum that Samsung cards functions the best. So it looks it does! Maybe a tip when you doubt to choose a SD brand.

I have mainly Samsung EVO and Sandisks Extreme A1 around. Due to the nature of our work I am doing nasty stuff to them and they also (Samsung) eventually break ;)


Until you don't go out with extensive testing with few hundred pcs and you are 100% sure they are not fake, its hard to say anything. Fakes come in the same package sold by renown sellers ... this whole SD card saga is more related to the luck then anything. In last few years I already throw away a pile of them.

The issue with burning images and getting the panic throw out from Raspberry Pi images is because the SD-CARD used and the image size do not match they differ by a small amount usually just a few megabytes on an 4, 8 or 16GB SDcard.  Does not matter which image software you use  and if you verify it or not unless they software fixes the partition up to match the card size it will throw a panic.

 

The latest version of Win32DiskImager will warn you the image size is different to the card size and allows you to continue but the produced image will panic.

 

The only way around the issue is using a partitioning tool to shorten the last partition back by say 500Mb so that the image size is guaranteed to be smaller than any card of the supposed size. Then image that card and it will work on any card of the supposed GB size.

Oh i think you use the SD cards indeed al little bit (mean a lot!!) more intensive then i should do. Otherwise is in the dashcam's my idea also that the Samsung's has a longer lifetime than the Sandisk.

 

But i agree with you: the only correct way to check it is to buy a lot and do all the same things and see how long the SD cards live. Offcourse with originals. But even then could there be a bad batch of a brand... 'SD cards are consumable items' do i read somewhere on the internet. And i think we should agree. :)

 

Btw: is the lifetime of a onboard eMMC better than a SD card?
