I want to install  a disk , copy a backup file to it and then remove the disk.

Is this possible?.

I´ve installed Open Manager Server Administrator, hot  plugged a new disk and configured it as RAID 0 and as virtual disk for the OS (Win 2008 R2) to recognize.

I´ve copied the file to the disk, but I don´t know how to put the disk offline to be able to unplug it.

Can you help me?
