  1. Did you stress test your PC right after you build it?

    If not, download Prime 95 and do the stress test.

  2. Run task manager (Ctrl+Shift+Esc) and select the "Performance" tab. If the CPU is 100% busy while you copy files even though nothing else is going on, then your drive is probably running in PIO mode instead of DMA mode - that can drastically impact it's performance.

    its not really when i copy files, its mainly when i try open apps, like ie or open my computer or try watch or listen to something it will have a big lag.

    i just checked. im not really sure but the performance tab has 4 sections to it. im guessing cause its a quad core, but when it has a lock up the last section goes to the top untill it stops having lag.
  4. OK, one CPU maxed out during disk I/O with nothing else going one sounds very much like your drive is in PIO mode. Here's how to fix it:

    --> Start -> (right-click on "Computer" ) -> Manage

    --> Click on "Device Manager" in the left pane

    --> In the right pane, double-click on "IDE ATA/ATAPI controllers" to open it up, then do the following for each channel in turn:

    -----> Right-click on the channel and select "Properties".

    -----> Click on the "Advanced Settings" tab

    -----> In the "Devices" box, make sure that the "Current Mode" is some variant of DMA

    If a channel is not running in DMA mode then that's your problem. To fix the problem, right-click on the controller and uninstall it, then reboot.
  5. it reckons there in Ultra DMA mode 5 and 6
  6. Guess that's not the problem then...

    Are you sure, it may say its configured to use DMA mode, but the actual mode may differ and may be PIO mode. Post a HDTune screenshot to be certain.
  8. I am having the exact p[roblem, it started three days ago. Have 1.5 TB Drives, and transfers now take about an hour to move 1 GB. Will Watch and advise if I see the Problem. Windows 7, and Vista dual Boot.
