Not sure if this is the best place to post this question, but what the heck. Here goes. Trying to put music files on my 32GB SD card and am having some very frustrating problems. In the device's defense, I am trying to transfer 22 GB of data...but anyway, the issue is that files start to transfer but about 10-15 minutes into the transfer, the SD card becomes unavailable and the transfer stops. From that point on, I can't even see the card from the phone. I need to do a reboot just to see the files/apps on the card. Right now I'm transferring the files directly to the card through a card reader, but this is a PITA that I won't be doing often. Aside from the hassle, I'd rather not pop the rear cover, battery, and SD card for fear of wearing out those connections. I tried using Samba, but the device needs to be rooted before that can work. I'd like to root, but having these problems is reducing my confidence in the device. I have a sneaking suspicion I might need that warranty... Has anyone had this issue? Does it sound like a phone issue? Android glitch? Something else?
