I am using LFS-based OS onto a 4GB storage device. Everything was working fine for more than 6 months.But suddenly, the storage device itself became Read-Only. No matter, what I do with this storage device. It always retains it's state with existing content.e.g. If I install Ubuntu, Windows or any other OS on this storage device by completely formatting it. OS get installed successfully but when I reboot, newly installed OS get vanished and storage device shows it's original data.If I boot from any LIVECD and mount the storage device. It get mounted but after creating/modifying some files/directories, changes get saved as long as device is mounted. But I loose the changes once I umount and mount it again.How am I suppose to troubleshoot this issue.
