I have a Windows 7 desktop with a 500Gb SATA hard drive and one 1Tb HDD (I think both are 5400 rpm) and it's been acting strange for a while. Two things are very annoying:

  1. When I save a file (such as an image) from web browsers, the browser sometimes freezes for a while, sometimes doesn't. The file doesn't start downloading until the freeze is over. I suspect a disk access issue since when I download multiple files one after the other, only the first on causes a freeze.

  2. When I created a file or a folder from windows explorer, it doesn't show up until I refresh the containing folder. Same thing when I rename a file or a folder, the change doesn't show up until I refresh.

I notice this behavior on both my disks. Is this a known issue? Should I replace my disks with faster ones or is the issue completely unrelated to HDDs?

Thank you.

Have you tried another OS? Try loading an Ubuntu LiveCD and tinker with that for a while: ubuntu.com/desktop/get-ubuntu/download – Blender Mar 10 '11 at 17:00

You can try a few thing: First you need to determine what kind of freeze it is:

Application Hang - Just the app in question stops responding. Ctrl-Alt-Del and all other apps work.
Soft Freeze - The whole system hangs up, Ctrl-Alt-Del may or may not work. Start menu and all open apps are hung. Mouse Moves on the screen.
Hard Freeze - Nothing Works during this operation, mouse is stuck till it responds.

If it is a quick application hang or soft freeze it is most likely an issue accessing that disk. Run a Chkdsk (drive:) -f -r on that drive and your manufacture's drive tools.

If it is a Hard Freeze there may be a problem with your RAM, I would recommend doing a Ram Scan.

With Windows 7 you can see whats going on easily as well to see what resource is being maxed(if any) by pressing Ctrl-Shift-Esc, then from task manager go to the Performance Tab, then click on resource manager.

Finally, you may want to use the system file checker(SFC) by running SFC /scannow

Thanks a lot. It's an application hang as everything else works. I'll run a chkdsk and SFC and investigate a little more tonight when I get home and come back here with feedback. – pwny Mar 10 '11 at 17:51
