None, it actually helps restore performance to drives if you do zero on them.

It only hurts SSDs.

There really isn't (a pro or con) one unless you are planning to sell that hard drive. If you are just trying to overwrite deleted files, you won't see much of a gain (if at all) in performance, since the files would be marked off to be overwritten and skipped anyway. So if you're planning to sell your drive, it would be ideal.

If you want to sell it and are afraid of information being recoverable use a freeware program called DBAN, it wipes to DoD specs: http://www.dban.org/

If you are just going to reload it then repartitioning (delete the old partition and reboot, then build new partition) is the best method. The secure wipe will sometimes kill and already weak drive because of all the "write" cycles.

For performance just repartition and reload, followed by a good defrag (I personally prefer Perfect Disk), with possibly one boot-time defrag run to place all the boot files at the beginning of the drive.

It depends, I noticed significant performance gains after using a hard drive after 7 months.

I got about 700GB used up out of 1360GB.

I want to sell it but i don't want any performance to be lost or any of the disk to get corrupted. If i were to do a disk wipe would it be bad for the hard drive?

Nope, a complete clean, wipe, format wouldn't be bad for any drive.

No you didn't - there is absolutely NO difference at all between the way a HDD writes data to a completely clean drive containing zeros and a drive full of deleted random data. The drive will re-write any required data regardless of what is there already. Any effects you thought you saw were placebo after all your hard work (or simply as a result of the (presumed) OS reinstall).

Pretty sure I did. I formated that drive quite often and installed Windows, over and over. There were definite performance gains after the zero pass.
