Immediately unreliable. I tried copying to it and immediately got errors with Win 7 64 bit. Did a quick format and still got the same errors. I had to fully format a brand new SD card. This is the first and BIG disappointment. Nothing brand new should have bugs and issues from 30 seconds out of the box to my SD reader. Rebooted, used a different USB, tried both USB2 and USB3, neither worked properly. Now I have to spend hours testing a new product. I tried several cards and they worked perfectly. 2GB, 8GB, 16GB, 32GB and 64GB. It's definitely not a hardware issue. I really just needed to move the data and get on with other things like life instead of wasting time solving SD card issues. It doesn't make me very confident that it will hold me. To be fair this is the first SanDisk product I've had issues with in decades so I'll be fair and give it 2 stars otherwise it'll only get 1. Reputation matters, at least for something. I'll update if it keeps giving problems and maybe if it lasts a few months without problems I'll update it too. I would be furious if I had to take the time to return a brand new device with no moving parts.
