FUNCTIONAL SKILLS

BACKUPS

BACKUP THEORY

The platters inside a hard disk spin very quickly whilst a 'head' hovers less than a hair's width above them, reading the data.

If you don't shut your machine down properly this head crashes onto the spinning platter causing scratches.

If a scratch occurs just at the point your data is stored, it can be damaged and you might not be able to access it.

Challenge see if you can find out one extra fact on this topic that we haven't already told you
