How to stop the spin of an external hard disk?

Hi, I have an external HDD, iomega 80 GB connectet through USB 2.0. The usb ports are part of an expansion card (usb & firewire).

How can I stop and start its spin at will?

You could try hdparm.

This is what happens:

[root@bestiaparda josean]# hdparm -y /dev/sda

/dev/sda:
operation not supported on SCSI disks

However it works with my IDE disks.

Perhaps you can put it to sleep mode via /proc or /sys then. I can't think of anything else, except scsi specific tools if they exists.
