I am installing a new HD (not the C: drive).
I see an option to fast format or regular format the drive.
Other than a regular format taking a long time, what are the long term
Sice this is a new HD, there is no data for a regular format to delete.
Does regular format provide faster access for adding files in the future?
As far as I know (haven't tested it), the short format only writes
enough sectors to create a valid file system. All other sectors remain
untouched. So you might only be writing to a small percentage of the
disk in that case (writing a "skeleton" if you will).
In the case of the long format, every sector is written. This would
flush out any "pending" bad sectors, and cause the hard drive to
spare any bad sectors that the hard drive detects. (The hard drive has
automatic features, for using spare sectors in place of bad ones,
and dodgy sectors are evaluated on write.) This can take a long time on
a large disk.
Using the long format, also gives you some assurance that most of
the personal information you ever put on the disk, has been
overwritten. And that prevents file recovery (scavenger) software
from being used. You'd be surprised how many of your old files
could be recovered, if you just did the quick format. So if you have
something to hide on that partition, you'd use the long format to
get rid of it.
