looks like their pcb board that holds the disk and the backplane 
does the "drive not ready" when the ata disk gets unplugged from the
chassis

but with 1 disk .. thats just 10 disks ( 3TB ) in 3U ...

i like my giant 100-200 TB per 42U rack idea better :-)

	40x 1Us with 8 disks each --> 320 disks @ 300GB per disk 
	( loads of fun with power and cooling and cabling )
