I would suggest installing gnome-disk-utility so you can check the "smart" status of the drive to see if it is failing. The program pulls in a few dependencies but nothing major. After it is installed you go to main>settings>disks when you open the program you should see a list of drives on the left. Hit Ctrl+S to open the smart status screen for the selected drive, and to see the general health of the disk. Hover the mouse over each line in the window to see what that information means. If it shows a "read error rate" value of anything other than "0", you need to take steps to save your data, and start planning to replace the drive.
