Is there a tool to analyse the performance of a hard drive
-
If a range of sector blocks are slow, mark it as used by dummy files. So the hard can perform better.

What makes you think that can occur?

From experience, when I copy a lot of files, tens of thousands, about same sizes. some of them go fast, some of them go slow. I think it has to do with bad sectors.
If you seriously are developing bad sectors, then you need to stop looking for tools to identify the sectors and do the following: 1) Backup everything you possibly can: start with the critical stuff, and work down. 2) Get a new hard disk. 3) Re-install on the new disk, and put the old one away in a quiet drawer somewhere in case you forgot something. One important thing I learned years ago: once a HDD starts developing bad sectors, it is a dead drive spinning. The rest of the drive will fail. Probably soon, but Murphy's Law states that if you leave it it will fail at the worse possible moment. Use what time you have to save anything and everything, and replace it now.

Thanks for the thoughtful answer. What I am talking about is original bad sectors coming from manufacture. Almost all hard drives have them, they just hide it so we normally don't see them. But those bad sectors could cause performance issues on hard drive. I am thinking about writing an utility that can write a certain size files determine by an arguments onto a hard drive and time the process, and find out which ones take longer than normal then mark those files as bad performance area to avoid. What do you guys think. My goal is to waste a little space on hard drive but keep the performance as high as possible for database and web access

Not sure that is true anymore. But if it is true then they are not being used - the hard drive software excludes them completely. So there is no point in skipping them.
