In the process of doing a clean install there is the option of deleting/ not deleting the current active partition prior to doing a "format c" operation. What is to be gained by deleting the partition and then creating a new one? Why not just reformat the current partition? Thanx

The usual reason would be to change size[s].
It never hurts to have a fresh partition table.
=====================================
If at first you don't succeed, you're about average.M2

And you generally don't want the C partition to be TOO big...better to have a smaller more manageable C partition for the OS & a larger D partition for programs & data storage. Some prefer to have several partitions. Also, the larger the FAT32 partition, the larger the cluster size, which means there's more wasted space (aka 'slack').

If you're using a drive that was previously in another computer it's a good idea to delete and recreate the partition as not all bios' will see the drive the same way.

Jam - I have created dual partitions for two different OS's but never a second one for data storage. How do you save data to the second partition? Is it simply indentified as "Drive E"? Thanx

when you install a program, the default install is usally something like c:\windows\programs files. You usally have the option to change this. Prior to the install create a folder on the data drive name it something (firefox) then "browse" to that folder, when given the option.

In addition to the partition slack tradeoff <see: http://www.storagereview.com/guide2... > older virus programs (virii?) used to hide in the MBR as well. Somewhere I remember reading some could be destroyed by running "fdisk/mbr" 3 times (not sure where I heard/read that....)

If you want a true "clean Install", it stands to reason that EVERYTHING on the partition should be "wiped" clean.
Deleting/recreating and formatting should serve OK in most situations, but Wiping (overwriting all sectors) will produce better results.
Yes, I know you may never see the results, but it's the simplest way to ensure a "clean Install"
There is nothing to learn from someone who already agrees with you.

There isn't a whole lot to be gained by deleting a partition and then recreating another one unless you reboot in between, in which case response #3 then comes into play bigtime.
But response #7 is doing it even better by wiping every sector anyway which IMO is the best way to clean install as it also kills boot managers and hidden partitions and those pesky drive overlays, any all such ilk. And virii too...
MBR three times? was that to get one up on the "two time" virus? <gawfa> silliest thing I ever heard of for virus control - as in some virus. (also see above) :)
A good wiper/hard drive tester is Bart's disktool that can fit on a floppy and address hard drives above the 8 gig limit that some earlier "wipers" can't handle. This one tool should be able to wipe all hard drives.
