The SD card was failing to write? It would have blown my mind if I reinstalled raspbian and the old config popped up.

I’ll have to keep this in mind.

I had an SD card once that would not fail to write (i.e. kernel does not show write errors) but when you read back it gets the old data. Tried it on multiple operating systems with the same behavior.

It was a more expensive SD card because I see more issues with cheap ones.

But it seems to me that SD cards suck at all price brackets. Maybe even some of the expensive ones are counterfeit?

You get a lot more money counterfeiting the expensive ones than the cheap ones.

In my experience, Sandisk have a much better warranty policy than the other cards that have failed on me. RMAs get approved, UPS prepaid sticker for return, and replacement sent by UPS (in Europe, at least). The failure rate of their cards doesn't seem different than others I've used.

Did you buy the SD card from Amazon or Ebay?

Yes in my case the pi would crash, and the SD card changes would revert. I don't know if its changed or not, but at the time you couldn't check uptime because the lack of a hardware clock meant it didn't know the time when it booted.

It took a while to figure out it was crashing everyday, probably due to the bad card, and the writes weren't taking. After more recent problems with other SD cards I'm trying the new SanDisk 8GB MSDHC Class 10 UHS-I U1 Industrial MLC micro cards after seeing them mentioned here.

That's like groundhog day.
