My hard drive keeps running a long time after bootup.

Hewlett-packard / Pavilion a6300f
June 28, 2012 at 06:04:06
Specs: Windows 7, Intel Pentium Dual CPU E2180 @2 ghz
Win Vista hard drive keeps running a long time
2 gig ram.
How can I tell what program is causing the hard drive to run almost continually.
I shut down my automatic updating and running of my Virus program already just to see if that was causing it to run at startup. It still is running.

Have you looked in task manager to see what processes are running while the drive is being read? Could be an indexing service.

Hold down the Ctrl and Alt keys, press Del, let go of all three keys, choose to run Task Manager.

In the Task Manager - Processes list, click on CPU twice at the top of the CPU column to list the programs so that the ones using the most CPU % activity are at the top of the list.

If the total CPU % shown at the bottom of the window is not high, then the hard drive activity is not significant even when it is active most of the time. .

There are lots of things that tend to run after you have started up the computer the first time on a particular day - the total CPU % will diminish eventually.
When you restart your computer after that on the same day, most of those things will not run right after Windows is loaded initially.

If you see TrustedInstaller.exe, that's associated with Windows Update It can use a lot of CPU % but that will eventually diminish and then it will have no activity at all.

How much free space is left on C ? If that's less than about 10% of the total size of C, your hard drive will be accessed more often. The less free space below about 10% you have on C, the more hard drive activity there will be, the slower everything in Windows will run.

Don't just use Task Manager. Click on "Resource Monitor" on the Performance tab and you will be able to view which processes are using CPU, which are using memory, which are using disk, and which are using the network. You can even see which files are being used by which processes.

This is far more informative when trying to track down disk usage. The processes that are using a lot of I/O are almost certainly not using a lot of CPU time (as I/O is relatively slow) so Task Manager alone won't help. Heavy hard disk activity slows the system dramatically even when CPU usage is almost 0.

Download & install CCleaner-Slim. Start it, click Tools, then click Startup. All the programs that load at startup (& run in the background) will be listed. Many of them are unnecessary. You can disable or delete the ones you don't want. All you really need loading at startup is security software (anti-virus/anti-malware) & possibly a few others such as wireless network, graphics (i.e., Cataylst Control Center), audio. But generally, the less you have loading, the quicker the boot & shutdown times, not to mention better overall performance. You should also be using a lightweight security suite, in other words, NOT McAfee or Norton. The free versions of AVAST, AVG, & Microsoft Security Essentials are the 3 most often recommended.

Hard drives are meant to run after boot up, if you mean processor is running slow then do what the people above me said to do,.

I am a hardware guy not a software guy but i try to help.

I think when the OP says that the drive is running you can take it that they mean the disk is being accessed (i.e. the access LED is on) rather than just that the disk is spinning. Continual access like this is not normal and will slow down the system. (As for the processor running slow - when not under load they are designed to do that.)

Although there are various ways to disable whatever is causing this problem, the logical first step should be to find out which process is causing this access; hence my recommendation to use Resource Monitor, which will show this. There is no point is just disabling stuff at random hoping that you get lucky, and CPU usage isn't necessarily going to tell you much.

A failing hard drive can also display this kind of behavior. Go to the hard drive manufactures website and download the diagnostic utility for the drive.
