Please don't be stupid and skip this step. So it was obviously a simple cabling issue between mainboard and the front USB ports/devices (the internal card reader at the front is also USB attached).

When attaching the same reader to the back ports of the PC everything went fine. But only when attached to the USB front ports. I then used the external USB reader/writer shown above which also started to corrupt images weeks later. I wasted a day to get the clue that it's related to the card reader being the culprit.

Images written with dd becoming slightly corrupted over time which resulted in weird software failures and kernel panics. I ran into this issue 2 years ago with the internal SD card reader/writer of my build PC back then. And then the user is in trouble since usually minor corruption issues look like software faults later on (that are considered 'Armbian bugs' then, reported as such and wasting our developer time and the user's time too) Win32DiskImager most probably would've written simply garbage with the above combination since it doesn't implement VERIFY (only latest 1.0 version implements an optional AKA useless verify step). What can we learn from this? Stop using and recommending crappy burning tools that do NOT VERIFY. The above external USB card reader/writer does not fail with good SD cards (Samsung EVO/EVO+ or SanDisk Ultra/Extreme/Plus A1) so for whatever reasons it's the combination of crappy SD card and crappy reader. Opos: 3904 MB, run time: 6m 17s, remaining time: n/a Ipos: 3904 MB, errors: 0, average rate: 10357 kB/s
Rescued: 3904 MB, errsize: 0 B, current rate: 8192 kB/s So do I have 4 failing SD cards? NOPE! Since when I use my laptop's internal SD card reader (also USB attached BTW) it works with all 4 crappy TF cards:Įtcher happily reports that burning now succeeded successfully and the same with ddrescue: Pass 1 (forwards)ĭdrescue: Write error: Input/output error Opos: 434765 kB, run time: 42s, remaining time: 5mĬopying non-tried blocks. Rescued: 434765 kB, errsize: 0 B, current rate: 2228 kB/s Is Etcher the problem? Of course NOT! Trying it also with ddrescue and same situation: ddrescue also already reports an error while burning:īash-3.2# ddrescue -force /Users/tk/OMV_4_Renegade.img /dev/rdisk2 This is repeatable with 4 of those crappy 4 GB TF cards (I stopped then testing). Try to burn an Armbian image and Etcher reports an error already while burning. I put the TF card into the SD card adapter, then the adapter into the USB reader and attach the reader to an USB3 port of my laptop. Also involved: a crappy USB SD card reader/writer: We recently replaced a bunch of crappy Intenso TF cards with SanDisk Ultra A1 at a customer so now I have something crappy to play with. Since I fear a lot of people still do not get that every burning tool that does not verify burning results is CRAP I just did an experiment. So why shouldn't be there firmware updates? And of course there's a controller running a software that can be buggy. Why? These things are complex, they have an SDIO interface to access the flash media and an USB controller to present the storage as mass storage device.

Thanks for the firmware-link, I never thought about a update to a card-reader/writer
