  • External hard drives are a great method to increase the storage capacity of your PC without having to open it up and replace the internal hard disk.

  • Windows 10 bugs continue to annoy users, and it now appears that owners of external hard drives are now afflicted. We report the issues and attempt to provide remedies as well.
  • We just finished talking about how Windows 10’s WiFi keeps disconnecting, and now people are reporting issues with their external hard drives:

So, I downloaded and installed Windows 8.1 x64 from the Windows Store yesterday, and now my QB-35US3 hard drives start disconnecting and reconnecting at odd intervals. Before the upgrade, I had no issues. USB 3.0 is used to connect the bay.

This is what one disgruntled user has to say. Also, the problem appears to be the same with USB hubs — the errors are the same as with external hard drives, according to what I’ve read:

My four USB external hard drives disconnect and reconnect every few minutes after upgrading from Windows 8 to 8.1. When a disk is idle, Windows disconnects it, and Windows reconnects/wakes it up when I need it. This is giving me many problems, and I’ve already deactivated this option in 8.1’s power management settings, but the problem persists. I can’t pause a video for more than a few seconds without Windows disconnecting the HDD. I have 16 TB of data and am concerned that this foolish feature may cause my disks to fail.

Another harrowing account from another afflicted user. We just published a guide on fixing slow USB 3.0 problems on Windows 10.

What should I do if my external hard drive continues to disconnect?

On their Windows 10 PC, many users have claimed that their external hard drive keeps disconnecting. However, by connecting your disk to a new USB port, you may be able to resolve the problem.

Users claim that this problem only happens when the drive is attached to a certain USB port. If you attach it to a different USB port, the problem should disappear.

If your computer has both USB 3.0 and 2.0 connections, try connecting your hard drive to a USB 2.0 port to see if that works.

Some devices have issues with USB 3.0 however, by connecting your device to a USB 2.0 port, you can prevent most USB 3.0 troubles. Keep in mind that utilizing USB 2.0 will reduce transfer speeds, but your hard disk will not disconnect.
