I have 5 multi-terrabyte USB 3.0 drives connected to my Dell XPS 8700 desk top PC. Of those 5 drives, 2 particular ones keep disconnecting and reconnecting (one of them has to have its' power cycled to reconnect) when connected to USB 3.0 ports. The other 3 drives work fine on USB 3.0.

The 2 "problem drives" work fine, though considerably slower than USB 3.0 speed, on USB 2 ports.

I've tried deleting the drivers and checking for hardware changes in order to get the drivers to reinstall. No joy.

I've verified that all usb ports (both usb 3.0 and usb 2) have their power shutdown options disabled.

I've swapped connections around and the same 2 drives keep getting disconnected regardless of which USB 3.0 port they are plugged into.

My various hobbies involve lots of data transfers of both large (sometimes over 100 gigabyte) and numerous small files (often thousands of files in the 100kB to 10 MB range). Although the hook-up I currently have is liveable,,, it sure would be nice if those other 2 drives could go at USB 3.0 speed.

Any help resolving this will be appreciated.

Thanks,

Tom Ackley

Hi there.

I think it is possible that one of your devices is messing with the others because of a power sharing issue with the USB ports. You could try is to fix it by going to Control panel -> Power options -> Change plan settings -> Change advanced power settings -> USB settings -> USB selective suspend setting and than Disable them.

Hope this helps.

Cheers! :)

Thanks for the suggestion but I'd already done that and I still have the problem. I also have gone into the device manager, selected each usb hub, and cleared the "Allow the computer to turn of this device to save power" option under all of the power management tabs. The problem is still there.

I recently found a USB 3.0 Express Interface card on sale at Best Buy for under $15.00, couldn't pass it up, so I bought it and installed it into my dual boot Win 7/XP system I built 6 years ago. From my experience with the USB 3.0 drive attached to that machine, the if card works properly. I think I should take each of the drives in question and connect them to the old PC's USB 3.0 card and see if the problem moves with the drive.

I guess I should try this for a couple of days and post the results.

Any suggestions you have in the meantime will be appreciated.
