Checking in Hard Disks |
| |
The most common error that
a hard disk encounters is a
read/write errors. Read/write
errors will not allow a user
to read/write a particular area
of the disk. This means that
the disk has developed a bad
physical spot. This error can not be identified
unless an attempt to access data from the faulty sector is made.
To detect the read/write error,
you can use utility programs,
such as SCANDISK and NDD. These
programs scan the surface of
the disk and read the content
of every sector. This process
is known as “Surface Scan”
or “Surface Test”
because the platter surfaces
on the disk where the data is
stored is scanned. On finding a problem with any sector, the utlity program reports it. |

Tip |
| Scanning an entire disk
volume is time consuming, so you must
mechanize this task to run when you
are not using your PC. |
