ChkDsk : Java Glossary

A Windows utility that checks the integrity of the file system and repairs damage. You should run it on all drives after any crash. You invoke it with Start ⇒ Computer ⇒ right click X: ⇒ properties ⇒ tools ⇒ check now ⇒ check scan for and attempt recovery of bad sectors.

Or you trigger it from a run-as-administrator command line.

Sometimes Windows 10 will do the chkdsk right away. Other times it will defer it to the next reboot.

ChkDsk normally requires a reboot to work. The screen often goes blank. Just hit shift to prod it along. Often the screen will stay blank. As long as the hard disk light is blinking, all is well. Sometimes the fool thing does the checks on each partition twice. The whole process can take hours, so don’t schedule it when you will need your computer.
