Is it possible to find out what corrupted my SD card?

Greetings and best wishes for '25

I have two SanDisk Extreme Pro in my Canon XA70 and they have recorded perfectly since new in early December.

Today however the camcorder complained when I inserted one of them, saying that it needed to be initialised. Luckily I have managed to recover the files using DMDE (SanDisk's "Rescue Pro Deluxe" which came with the cards failed miserably at this task).

I had previously used the card in my cMP3,1 and my 11" MBA to transfer footage using this Anker USB card reader, which evidently isn't anything fancy.

Oddly enough, this was the first time this error occurred even though I had used the card with that card reader before on both Macs and then recorded to it without issue.

I'm curious to know what caused this. If it's the card reader I'll need to find another one. If it's the card I would need to replace that. But I'm wondering if there's anyway to figure this out.

A complete long shot obviously but I thought I'd ask.

Cheers and TIA
Philip

I would be most suspicious of the card itself.

Thank you. I suppose there's no way to know that for sure, like a Console log on the Mac or such?

That's not how data corruption works. The data on SD cards is fine until it's not and it could be due to any number of causes.

Just to be clear, I'm suspicious of SD cards in general. I've had more than one of them just "fail" on me. I use them to hold music media in Porsche vehicles because that's the input port they have for holding media. My card would work well for a while but then after 12-18 months or so they just become unreadable. Whether it's in the internal flash that goes bad or the connectors eventually go bad, I'm not sure. Haven't had the issue with USB flash drives holding music in BMWs.

Hm. I am going to give this a try with my SD card.
