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:
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.
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?
