Due to a slightly defect cable Windows sometimes gives me a warning that the device is taking too much power (pop up in notification tray). It then gets disconected. Unfortunately, I cannot safely remove it, as it claims the disk is still in use. Usually, if Windows claims this, I do not care and remove the cable. In this particular case, however, the device remains shown. In the explorer I can even open some cached folders. If I reconnect the drive on another usb port, it is detected as new device but not displayed. I can remove that one safely now, but with no effect on the falsely shown one. It is present even after log-out log-in and still cannot be removed safely. Is there a way of dealing with this apart from a restart ...and buying a new cable to avoid this to happen in the first place, of course.

This discussion has an interesting answer, but I do not see an exclamation mark in my device manager.


Found it, but seems to require a restart, something I'd like to avoid.

    Isn’t your slightly defect cable causing a short circuit for a moment? I’d prefer a hardware solution in that case. – Melebius Sep 15 '15 at 9:30

    @Nikhil_CV Logged in as administrator. Now I found the exclamation mark and the device was present in the disk section. Any removal action there resulted in "effect takes place after restart" though – mikuszefski Sep 15 '15 at 9:41

    Since this is a hardware issue, stopping and starting the power supply (what happens during a restart) is what doing the trick. Till then Windows assumes the device is active. Are you sure only the protective shield is damaged? That can cause interference, depending on where its placed or grounding or even short circuits.. . . . . . . . Proper removal of device will not happen as windows/hardware controller already tried to reduce/stop the current flow through the port. – Nikhil_CV Sep 15 '15 at 10:07

    In any case I agree that I should get a new cable soon. – mikuszefski Sep 15 '15 at 10:32

    If you know the cable is defective , just replace it, you can cause serious hardware damage if you continue to use a known defective cable. – Ramhound Sep 15 '15 at 11:08

Restarting is the easiest way to get the device cache flushed as well as recheck the presence of the device.

Since the faulty cable causing noise/Short circuit is involved, it really requires the power cycling.

Some questions related to device cache flushing:

  • It probably comes down to a restart. It is amazing that there is no proper forced umount/eject possibility. All other solutions I found also need a restart, eventually. I should be happy that changing the desktop background does not require a restart in Windows. Apart from the fact that I seriously must change my cable, all this revealed inconveniences are ...well... inconvenient. – mikuszefski Sep 18 '15 at 7:36
