Re: Bad clusters

Just because a very small area of a platter may show signs of magnetic loss,
doesn't mean the hard drive is failing itself. Except for SMART capability,
cache size, and rotational speed, firmware intervention, there's nothing
different about today's hard drive physically.

It is prudent to have a backup clone available at all times, Leastwise, an
image backup on another physical hard drive. Whether the current used hard
drive for XP is showing signs of failure is immaterial. And, may be too
late for full use when used as source for a clone or image at that point.

That is a bit unclear. A sector is 512 bytes in size. A cluster is a
group of adjacent sectors (1, 2, 4, 8, 16, 32, 64, or 128) that is
treated as a single unit when disk space is allocated to files.



Its possible to map out bad areas of hard drive, and will still be good if
its just a few cluster problems. Use the hard drive manufacturers
software
for this. It will update the hard drive firmware not to use this portion
of
hard drive. A bad sector, replace it as soon as possible.

With modern drives, any indications of bad areas on the drive are most
likely a indicator of the probable imminent failure of the entire
drive.
