Port on the back are grounded better therefore have better power.
almost all new slim HDD or devices they recommend rear USB ports.

I haven't heard any of that before. On a desktop, front ports are connected via a USB cable directly to the motherboard - I don't see how that ground wire would be any less capable than a connector soldered to the motherboard. On my laptop (can't speak for all of them), all of the ports are soldered down. They all have the same power output as well. Where did you read that?

External enclosures/drives/etc are recommending rear ports? Can you tell me which ones? I'd like to read up on that one, as I'm in the market to purchase a portable 1TB drive for backing up my WHS, and I certainly don't want to be restricted to certain ports.

i tried a different port. same problem.

If it's happening to other USB devices, then I'd say it's a driver problem. Possible culprits are the USB drivers and chipset drivers.

I still think it's a driver issue.

i have come across this thread and it sounds very familiar.

File transfers hang when transfering two or more...?

how do i update my usb drivers?

First, make sure you have the latest BIOS available for your motherboard. Then, you'll have to use the Vista x64 system drivers, since there are no Windows 7 x64 system drivers available. There are no USB driver packages, so this is the best you can do. You might want to contact MSI and tell them what's going on - they might have some beta Windows 7 system drivers they could send you.

I also have the same problem when copying large size files from internal HD to USB flashdisk or USB portable HD.

The copying process started way too fast (>80MB/s which is impossible because my previous Vista maxed at 25MB/s) in the beginning and then halted in the middle. After waiting for a while, a notification "delayed write failed" popped up and windows explorer can't read (but still detected) that particular drive.

I installed Windows 7 Ultimate x64 BETA months ago and same thing happened, but without "delayed write failed" notification.

My previous Vista SP1 x64 doesn't have this problem.

Now I am using TeraCopy (thanks Tews!) to copy large file, but I am still looking for another solution.

My specs: Acer M5641, Q6600, 4 GB RAM, nForce 630i
A clean install of Windows 7 Professional x64 (not activated) with newest windows 7 nForce chipset drivers from nvidia.
