Anyone using the
SanDisk Extreme PRO 32GB UHS-1/U3 95MB/s cards and having issues in quality? I just bought two off of and shipped from Amazon and had I/O errors and fails the 2nd night of light use transferring files to PC and memory corrupt errors in camera. I formatted once in the computer so the K-3 could read it then formatted in there before trying to use it again. I decided to make that my #2 used for jpg backups and video then used the other card as my #1 for raws. Now day 5 and the "good" one started throwing I/O errors when copying 4.8GB of photos over to another computer. There are three folders on the card from three different days of photos. First two folders are unreadable, third one will open, but there is clearly photos missing and a weird single 2.5GB file labeled "USBC°*".
I'm asking out of curiosity, not so much advice since these cards clearly appear to be defective to me and I could never trust them with my memories. I've been using older 8 & 16GB Lexar & Transcend cards with no issues what so ever for a year in same camera. 1st time in ages where I've had memory card issues like this and was hoping the sandisk cards where higher quality, but seems thats not the case. I'm going to give Sandisk another shot as I just requested replacements from Amazon. Hopefully the next pair are better than this.
