I am currently using a Windows 8.1 machine and I am having this phenomenon issue where I can get the machine to detect the card for about 1/2-2hrs (no scientific testing applied yet), but if i leave the machine alone for awhile and I insert an sd card into either the built in card reader or the usb connected reader, I get nothing, not even leaving it inserted for several hours. Has anyone noticed this issue and what did you do to fix it other than "buy a Mac" I did that already and hated the OS.
