Hi! I've recently asked for another issue on this forum and was helped a lot, so I thought you could help me with this tedious problem too.
I've just formatted and reinstalled Windows 7 (64bit), reinstalled drivers from original cd and all. Now I have a problem with my external HDDs, yup not with one but both my devices suddenly have the same issue.
Le me start by saying that I've ever had problems with USB ports and transfers (continuous disconnections, slow transfer... not just with HDD but also pendrives, etc.), I don't know how i did fix it but in recent months they all worked fine and I was pretty happy
Now after the format it all started again. I need to transfer large amount of data and tryed with one file of various sizes (400M-3GB) at a time and while the transfer starts nice (110-120 MBs) it suddenly drops to 0 after few seconds, it takes longer with larger files but they all just stop between 50-90%). When they stop the PC continues running the transfer at a speed of 0 and cannot be canceled (tryed, waited, it just does not stop... I canot even remove the drive safely cause it's busy).
I've tryed with much smaller files and they works fine.
Another thing: when i plug and turn the HDD on Windows advice me that they can perform faster with a 2.0 usb port, but so i cannot explain why the transfer have an high speed when starts.
I know it's probably a drivers issue but I really doesn't know where to beging to fix this. My PC has two USB 3.0 on the front (NEC host controller driver installed for those) but they just did never work fine, so I'm sticking to back ports.
Can someone help me, please?

Ok I've already an update for you. I tryed to change the USB port and... they work there! Mouse, keyboard and other devices works fine in the first port too, but HDD and pendrive have that issue that is not present using a different one.
Now what I'm thinking is: could the person who assembled the pc just have screwed up connecting usb ports? That would explain why my USB3.0 newer worked fine and I have misteryous issues with normal ports too...
