First Gen Evo's had a bad batch of SD Cards...and from what I heard and saw was that HTC changed them to Samsung branded 8GB cards...from the Sandisk they were using. Check your cards to see which one you have. Also have you upgraded your Evo's to the latest OTA update? I heard that they addressed some memory card issues with one of the 3 OTA's they have released.

I would hope if the SD Cards are bad, that HTC or Sprint will replace them free of charge...since it came with the phone...and should be covered under warranty. Not sure how they would go about it though...I would call and check first.
