This post i tested on my own PC.
Software: HDD Regenerator 2011
Website: DPO Software
For a while+for gaming i make a new specs:
My PC specs(also test were made)
1- Western Digital 80GB(OS)
2- Maxtor 80GB(game file)
3- Seagate 3TB(personal file)
All hard disk i use SATA connector and SATA mode i change to IDE(to make it fully work)
I run defragment and check disk(windows utilities) but all seem not work. Waste my time.
My hard disk(OS) "hang" quite a lot of time make all my running program "not responding" and i notice multitask is not smooth.
Make sure you use SATA mode=IDE(you can change it back)
Download and install HDD Regenerator 2011 on your computer and run it.
For hard disk contain Windows/OS you need pendrive/CD to make it bootable. I tested with bootable pendrive. Just follow instruction on screen it not complicated at all.
Its work like magic!
This software is shareware. For unregistered version it only allow repair 1 bad sector while for registered version it unlocked full feature. Just googling for serial/crack. I found one and it work like charm.
