Is SanDisk sd cards becoming corrupt common? What kinds of things will cause it even when used regularly?
Had years of pictures deleted today even though it didn’t touch water or it was never dropped and all it did was stay in the camera now it says card unusable until formatted
Regardless of the storage medium, if you have one copy of your data, you have zero copies. SD cards are especially flakey, but all storage can fail.
You may be able to recover it with software (dont format the sd card, put it in a computer and try software like ddrescue), or paying a data recovery service.
Either way, you learnt a lesson today. If its important, have multiple copies. Burning your photos to DVDs or blurays and make sure there are duplicates (if not triplicates). Sorry for your loss.
Wait, you mean you had years of photos, the only copy of which was on a MicroSD card, the least durable storage media known?
…Geez.
The secret is just don’t do that. Never trust a MicroSD card as the only copy of anything.
