I had a sdcard where these where so thin that they literally broke of if you rubbed the contact points the "wrong" way with your thumb. 1 or 2 had broken of without me noticing it which lead to no boot without pressure being applied. Because the plastic separators where so thin it was really hard to see. Rubbing them all of in a controlled way (using a fingernail) made the card work again. Heh
Really bad made card.. The plastic ended up breaking apart, but it still works fine.
Yes, I checked the card for defects and it has none. I had a brand new 32GB SanDisk Ultra which cracked on the corner after a few days use (maybe half a dozen insertions) and so once popcornmix had steered me in the right direction I gave the card a thorough once over in case the same had happened but all is well. A dab of superglue fixed the SanDisk and it's been right as rain ever since (great card, no corruption at all and it gets a hammering in an overclocked Pi).
The strange thing about this other card which has now failed is that it isn't being removed - it's in an always-on Pi for the last 6 months, but eventually the Pi had to be rebooted and that's when it failed. Maybe it was just marginal to begin with... I'm still toying with the idea of tinning the contacts with a soldering iron to increase the chance of a good contact.
