I upgraded from Windows 8.0 to 8.1 recently and ever since the external USB drive (with power supply) connected via a powered USB hub started disconnecting and then automatically connecting after a few seconds. Here is what I did:
- Checked event log - nothing is there!
- Removed the drive from the USB hub and directly connected to the laptop USB port (error still coming)
- I checked the power option and kept the hard drive to be always on, but did not solve the problem
Any ideas what could be the issue? I have seen a Microsoft KB article http://support.microsoft.com/kb/2416007/en-us that discusses the same issue, but it is only for Windows 7.
The pattern is, it happens about 15 minutes after I switch on the laptop and then after that every 15 to 20 minutes.
