Hard Drive Help Pages
8.When I run
scandisk on my hard drive it shows bad sectors. What are they
and what should I do about it?
Your Hard Drive is made of a solid disk which
is covered in magnetic particles just like a cassette tape.
The information is stored on this disk in sectors that are
numbered. If the magnetic surface of this disk becomes physically
damaged then the storage and recovery of this data will not
work properly. Any sectors that will not save and recover
data properly are said to be bad sectors which are of course
unuseable. Although you can keep on using your drive with
bad sectors it is common for the bad sectors to spread which
effectively means that you will end up losing information.
The best solution is to replace the drive either under warranty
or with a new one. To test
your drive properly try the manufacturers own test utilities.
