I have a solid state drive that was working fine until yesterday.I booted this laptop from it for months. I had set the SSD up with the dd command from my hard drive.Yesterday it wouln't boot, ie startup said no bootable device found. I then put the hard drive in the laptop with Fedora24 4.8 kernel in order to find out what's wrong with the SSD.When i attach the SSD through a USB cable, ext4 FS errors appear via dmesg, something along the lines of :ext4 fs error ..buddy.. bloc  wrong ...Also, because the SSD was a boot device, as soon as I attach it through USB, perhaps important directories get mounted in the same / and the filesystem starts to misbehave.What utility can I use to attempt fixing ext4 fs errors with?  Fedora 24What sequence do I follow?
