I am quite surprised to see that Windows Explorer is locking my external hard disk. Is there any reason why explorer.exe is holding on to my external hard disk?
Before I was trying to detach the external hard disk, I was opening a
csproj file using Visual Studio 2008. I made sure that I closed down Visual Studio before trying to detach the external hard disk. There was no other active program except Google Chrome, from what I could see, that was running.
