Buffer memory are solid state memories (Static RAM for Hard disk) that will help store data/commands temporaily to help speed up the access time of the drive.
Since hard disks are mechanical devices, their access speed will not match up to access time of solid state memory since they have to position their R/W head to the correct tracks and sectors first before R/W can take place.
Typical access time for hard disk is like 8ms, static RAM access time is like 10ns.

The processor is a fastest one compare with your hard drive. The processor should wait for some time till the hard drive take the reqired files. Think like this, the processor give request to take a file. The harddirve will take the file and store it in a temprory space. Till this process undergone the processor can do some other process is it? for this purpose the buffer memory used. The buffer memory is nothing but static ram. Not only in the hard dirve the buffer memory used in many places such as printers.

A certain portion of hard disc memory is utilised as buffer to store the temprory files during processing. This over and above the RAm memorry. I can give you a link that deals with hard drive problems. Some drive problems can be easily fixed by yourself using easily available tools. I found the info at http://fixit.in useful. Try this site, if you can get what is required.

Buffer memory is used to hold data while the hard drive processes other information at the same time.
