Just finished building a new machine. Foxconn 590 SLI mobo, 500GB Maxtor hard drive, Vista. At times, hard drive acts up, takes all the resources and makes my PC unusable. Hard drive activity light constantly on when that happens. Really slow copying data from a DVD and my external hard drive. I never had this problem before, even with a low end machines, I was able to copy data to/from a hard drive and watch a movie stored on the hard drive at the same time. Please, help.

Does it happen on start up or?...

I haven't used vista yet but if possible try Ctrl+Alt+Del explorer under processes...then click on the vista version of applications and click new task...Then type in "explorer" and run that. It should bring your startmenu and all that jazz back up...Not sure if vista is like XP though so it might be dif or completely removed feature...

It is odd that it's taking up resources. I use to have issues with freezing and what not. When my computer would start up it would do the same thing for about 2 minutes and it would go away. Try to see if in the processes task if "Dumpprep" is on the list.

Start up is not too bad. I'll try a few things. Maybe use a different sata port? Also, on start up there is a floppy drive error, but I don't have one. I have to press F1 to continue. Then in Windows Device Manager there is a floppy drive listed...?

How much memory do you have? It might sinply be that you don't have enough memory and that your system is getting all it's "information" from your HDD which make it very slow. At this point your system will be look unresponsive, almost freezed. My laptop used to do this when I had only 512MB of memory, but now with 2GB it never happenned anymore. With Vista, I'd say that 1GB is a good minumum, below that what you mention will surely happenned if you multitask (do a lot of stuff at the same time, which use more memory).

I have 2 GB of Corsair memory running at 750Mhz. I still have to go and manually change timings to 5-5-5-5-12, right now it's 18. I don't think it has something to do with it. Like I said, it only happens when the hard drive is copying a file and I am trying to do something else. The computer is unresponsive at that point. The copy speeds are slow.

How much RAM do you have installed? IF you are light on RAM the system will use the HDD as memory.

Just throwing out some other ideas and things to look for.

1) Latest motherboard drivers?
2) Defrag the drive
3) Virus/malware/spyware scan for possible infection
4) Virus/malware/spyware scans running in the background
4) Set page file size

Checking the Task Manager to see which apps are running is a good idea, at least then you will be able to tell what keeps hitting your hard drive.

Good luck!

I have the latest chipset drivers and BIOS. Do I need to defrag if I just reformatted the hard drive prior to installing OS? I don't use Antivirus software, only go to a small list of websites that are safe. Not sure about page file size. Can you elaborate on that, please?

May be it is the 'System Restore' feature that is currently copying files?

Did you tried to your computer alone for a while and see if it will stop?
If yes, reboot and see if restarting or not.

Start the 'Task Manager' and under 'Performance' (I believe), there is a button at the bottom that will bring you another window. That Window is very helpfull and if you choose the 'Disk', you will see all currently accessed files. You can sort on the read or write to see the highest activity. I use that very often to see who is messing with my HDD!

Have none of you heard of "superfetch" and "indexing" ? Go look it uo and you will know why your hard drive is slow. Find out how to go into system services and disable "Superfetch and turn off indexing under your drive properties.
our hardrive using resources, it is VISTA, period.

Vista I/O overhead is notorious, and well documented, this is supposed to be fixed in SP1.
Windows 2000 W/SP4 works well.

Thanks for all the responses. I appreciate your help, guys. I know about superfetch and indexing, but I have been running Vista on my previous computer for 8 months and never had this problem. I was able to burn a dvd at 16x and watch a movie stored on the hard drive at the same time. Now, my system is twice as fast and I am having these problems. Few other things that might or might not be related to the problem.

1. In the device manage the processor model is unknown even though it says AMD 6000 on vista welcome screen. I will install AMD drivers today to fix that.
2. My memory is running at wrong timings 5-5-5-5-18 instead 5-5-5-5-12. I will manually change that.
3. At start-up, BIOS reports a problem with a floppy drive even though I don't have it. I will go to BIOS and see if I can fix that. It's funny, but in device manager it reports a floppy drive.
4. I will try different SATA ports. And check drive configurations, RAID options, etc in BIOS.
I will report tomorrow.

I don't want to make this a Vista thread. I am sure there are people who have problems with it. Like I said, I have never had problems with it on my old HP system. Now, I built my own machine and it is having these issues. I will report back tomorrow after all the steps I outlined above. Thanks to each and everyone of you.

Glad to hear you have the latest mobo drivers. It makes me laugh when people reply with something like, "What?! The motherboard needs drivers too?! Huh, what, chipset, what's that?!"

My experience and habit has become and still is, to perform a defrag (using the windows utility) after installing windows, any updates, and all the latest drivers. Then install an anti-virus, disk utilities, spyware/malware checker, and secondary software firewall. And then finally use the disk utility to defratg the drive again. Also, I usually defrag the drive at least once a week, after installing and removing any applications, or deleting large (>500MB) amounts of data.

Generally speaking, whether you only visit "trusted" websites or not, it is a good idea to install anti-virus and spyware checkers anyway.

Lastly, if the OS requires more RAM than you ahve installed to run applications properly the OS has to cache memory to the hard drive in the form of the paging/swap file. If the page/swap file is set too small or if you allow windows to dynamically manage the size of the page file, it can cause unnecessary disk access. Below is copied from the WinXP Help Files on how to re-seize the page file. FYI, the page file should be (ideally) 1.5 times the amount of RAM installed in your system.

These are the classic symptoms of a hard drive working in PIO mode. I’m not sure where you would check for this with SATA drives in Vista, but with PATA drives in XP it’s under Device Manager > IDE ATA/ATAPI controllers.

One word: Vista. You answered your own question.

Cenarius, I thought PIO mode was available only for IDE hard drives. Can someone else verify this? I will look tonight to make sure it is set to DMA and not PIO.

Did you check which process and which files were heavily used using Vista tool (Resource Monitor)? I found that tool very usefull and XP should have that too.

Every time I see my HDD light too green, I look who is doing what.
