    Hello! I am running Windows 7 Home Premium 64 bit. I've been seeing very slow file operations since making this PC my main computer earlier this week. My system specs are listed below my signature. In addition to the specific example below, the problem appeares copying image files from a CF Card (see specs) and to an external USB 2.0-connected hard drive. Interestingly the transfer rate is "lightening fast" between this PC and a PC I use as a NAS over 75" of Cat 5c cable at 23.4 MB/s.

    A specific example: On my data drive (the Hitachi 2TB) when I copy 150 image files (about 729 MB) from one folder to another it takes approximately 27 seconds. When I delete the 150 files from the destination folder it takes about 27 seconds. The drive is about 20% full and has been defragmented recently.

    1. When I boot in Safe Mode the copy takes 4.7 seconds and the delete takes less than a second.

    2. I boot after selecting Selective Startup in msconfig leaving Services normal and disabling all Startup items the original problem persists.

    3. In msconfig I disable all non-Microsoft Services and all Startup items then reboot and the original problem persists.

    I would appreciate suggestions of any further tests or diagnostics I can run to isolate this aggravating problem.

    Thanks - Dave

    Is your BIOS up-to-date?

    Are there any firmware updates for the Hitachi drive?

    Is the PC up-to-date with patches?

    My first guess is security software that checks every byte as it flows around the system, but its not checking when data goes to the NAS because that's offloading only and my second best guess is the chipset drivers that aren't very compatible and/or not optimized.
