Subject: Ejecting a USB drive using Cygwin (sync)?
Date: Tue, 23 Jan 2018 12:14:17 +0100
X-IsSubscribed: yes

I'm looking for a command, which would allow me from a shell script to prepare the removal of a USB device (stick, external hard drive etc.). With other words, after issuing the command, I should be able to physically remove the USB device.

Can the `sync` command be used, for instance

    sync -f /cygdrive/e

assuming that the USB device is on drive E:? The man page of *sync* is a bit vague in this respect. Or is there another Cygwin command which can be used for this purpose?

Ronald
