Win 7 ext USB HD's recognized by disk management but do not show up in Windows Explorer. Flash drives recognized but not multiple ext USB HD's.
Problem is consistent on multiple known good USB 2 and 3 drives that work fine on my Blu-Ray player. HD support was working previously on computer. Sudden start with no noticeable cause.
Problem is consistent on both USB 2 and 3 ports on both back and front of machine.
Windows 7 Professional (x64) Service Pack 1 (build 7601), ASRock Z68 Extreme3 Gen3 MOBO.
Tried uninstalling USB drivers, cold start, USB driver reinstall, with no change or improvement.
Ideas? HD hardware is good. USB support is incomplete. Most likely solution in MOBO softs or Win 7 softs?... or both?
