Windows 7 64 bit dropping connection to USB Ext Drive

[westsidebill]

I have seen several OLD posts on the net about Windows 7 64 bit losing connecting with USB external drives, when copying large files...I have also NOT found a resolution.

Does anyone know if MS ever solved this issue???

HP Pavilion e9180t
9 GB RAM
Intel i7 Processor - 920 @ 2.67GHz
Intel X58 Rev 13 Chipset
nVidia GeForce GTS 250 Video adapter

Seagate 1TB Expansion Portable Drive (the drive that is dropping connection)*

*Drive works fine on Vista and Win7 32bit

Note: MS KB97697 patch does not fix, as I do not have an nVidia chipset

Any assistance would be appreciated.

I am hoping to find a software (Windows 7) fix to this issue, rather than having to install a new hardware...especially since it seems to be a Windows 7 64 bit issue.

The way I fixed it was to switch from a Unitek USB 3.0 adapter and drive dock to a VanTec USB 3.0 adapter and drive dock. The Unitek hardware seemed to be the culprit.
