Well...
Stress test still running on reputable brand with no PB, after 6 or 7h.

During this stressing session, we found a few broken SD, from another reputable brand.
Not all cards, though, but enough to put some confusion... ;-)
Something else added to the confusion, was an article on a Linux block layer issue...

OK.
Now, at least, we have a "stressing" tool and a stack of RPI in case of doubt on SD :-)

By the way, is there any well known bench mark tool for SD, on CentOS or OpenSource ?

did this happen with multiple SD-cards ? if not, I strongly suspect that the issue is that particular card , not the OS. it rhymes extremely well with either a faulty card or a card whose firmware was doctored to report a larger size than the one it really has

Been there, done that! After seeing a large number of ‘infant mortalities’ with RaspPi 3+ setups using cheapie ‘no brand’ microSD cards, we made the switch to using only ‘name brand’ cards from reputable manufacturers. Problem solved.


Cheers!
