AHCI on Windows 7 - Drive icons for attached drives do not "refresh" when drives removed

When a secondary SATA drive is removed from the running PC, sometimes the icon for the recently removed drive does not quickly disappear. In fact, sometimes it stays visible for several minutes, and even the drive folders can be seen. Selecting "refresh" does not solve the problem.

Is there a way to force Windows to refresh quickly and automatically when a SATA drive is hot-swapped?

Thanks!

Are you using the Windows tool to Safely Remove Hardware and Eject? If not, that is probably why.

This is the nature of the beast, as it this is how it is designed to work.  The alternative is for the O/S to constantly probe & scan and look for things to change, and in the process, kill performance.

No free lunch here ... if it scans more frequently, then performance suffers significantly.  YOu really need to live with this because you won't like the alternative.

Is there a way that I can prompt Windows to probe and scan "on demand"?

Your secondary drive would not be hugely different from any other removable drive, and I have not seen a Windows tool for that. You insert the drive and Windows Explorer then knows it is there. I do not think you can prevent Windows from knowing the drive is attached, while waiting for you to look for it.

run diskpart with rescan option   This can be put into a VBS or powershell or .BAT script and you can stick it on the desktop and make an icon for it.

True, but that does not stop Windows from already knowing about it (to the best of my knowledge).

Any advantage to using Windows Server or a Linux distro?
