ok, so i deleted everything on the card, updated and the beta is not unmounting on an empty sd card, but i just started seeing some other issues while trying to copy files back onto card. Seems after a few seconds of trying to copy the usb disk disappears, i will research more and try to narrow it down when i get time. I can make files and folders but cant copy my iso's. Its possible this is on the computer side, not the usb side.
depending on what file manager i'm using they're I/O errors or 'Drive is not available' or 'directory not available' and the stick has unmounted at that point. I jumped to a couple different firmware versions and this is happening with all of em. Hadn't seen this before i updated to 1581. While i doubt remnants of 1581 remain and screw up the drive after downgrading, maybe its possible? Its not consistent either, sometimes i can get several hundred megs copied before it happens, sometimes i dont get anything copied (sits at 0 and eventually unmounts). If what im copying is small enough i can get it all on no problem.
maybe its something in the addressing, there was an 'ISO' folder last time it was mounted, now its the entire file path...
