Sometimes, when using the command prompt, the cd command finishes quickly, but often it takes several seconds. What does it indicate? What's the bottleneck?

Is the location you're trying to cd to a network resource, perhaps? Or maybe a hard drive that needs to spin up first? What happens when you try to open that location in Windows Explorer? – Indrek Jun 8 '12 at 8:42
it's a hard drive. that location does open, but slowly. – prongs Jun 8 '12 at 8:43
A couple of things to try: 1) defrag the hard drive; 2) check SMART attributes with HD Tune or similar utility; 3) run chkdsk and see if it reports any errors. – Indrek Jun 8 '12 at 8:47
how do i find the spinning speed of the hard disk? – prongs Jun 8 '12 at 8:58
HD Tune or Device Manager can give you the model number. Type that into your search engine of choice and you should find the specs, including the rotational speed. – Indrek Jun 8 '12 at 9:03

A couple of things to try:

  1. Defragment the hard drive. The built-in defrag utility is fine, though for more advanced tuning (system file defragmentation, free space consolidation etc.) you can look into third-party programs like Auslogics Disk Defrag.
  2. Check the hard drive's SMART attributes with HD Tune or similar program. See the Wikipedia article for a list of attributes, including those that are potential indicators of hardware problems.
  3. Run chkdsk to find and fix errors with the filesystem and bad sectors on the hard drive.
