Wouldn't it be sufficient to fire 4GB worth of any data (for instance some brand new hexadecimal zeroes freshly out of /dev/zero) with dd? Like

Code:
dd if=/dev/zero of=/the/raid/somefile bs=1G count=4

True, this will be off by the overhead of /dev/zero, wouldn't that be negligible given the bandwidth of disks and the memory interface (which are apart some orders of magnitude)?

I hope this helps.

GNOME-DISKS(1)							gnome-disk-utility						    GNOME-DISKS(1)

NAME

       gnome-disks - the GNOME Disks application

SYNOPSIS

       gnome-disks [OPTIONS]

DESCRIPTION

       gnome-disks is the command to launch the GNOME Disks application. Disks provides a way to inspect, format, partition and configure disks
       and block devices.

       The Disks application is single-instance. What this means is that if the application is not already running when the gnome-disks command is
       invoked, it will get launched and the command invocation will block until the application exits. Otherwise the existing application
       instance will be used and the gnome-disks command will exit immediately.

OPTIONS

       The following options are understood:

       --block-device DEVICE
	   Switches to the Disks application and selects the block device given by DEVICE (for example, /dev/sda).

       --block-device DEVICE --format-device [--xid WINDOW-ID]
	   Shows the "Format Volume" dialog for the block device given by DEVICE (for example, /dev/sdb1). If WINDOW-ID is given, makes the dialog
	   transient to the given XID.

       --help
	   Prints a short help text and exits.
