Ubuntu – How to check the RAM and hard drive for errors


What tools can I use to check that my memory and hard drive are still working correctly?

Best Answer

Boot with Ubuntu Live CD/USB stick (or press & hold Shift before the splash screen, to enter GRUB menu), and select TEST MEMORY with memtest86+! See this illustration, don't wait for graphical UI!

To test HDD, you can use S.M.A.R.T. data reader, palimpsest disk utility, press Super/Dash button, start typing Disk Utility (for Gnome: System > Administration > Disk utility), and check your S.M.A.R.T. data (YOU MUST UNMOUNT THAT DISK FIRST, YOU WANT TO CHECK ITS FILESYSTEM - that's why, use a Live CD/USB stick - for S.M.A.R.T. reading, the disk could be mounted/used)!
