Make sure the disk cooling fan is present and working, just to the
right of the disk sleds.

Many drives can do a delayed spin-up themselves, often something
like <SCSI-ID> seconds of delay before the motor starts, so the
startup current peaks are distributed. So ID 0 starts immediately,
if you put the second disk on ID6, it starts after 6 seconds delay.
