Some of my older SATA drives like my 74GB Raptors have a jumper that is supposed to allow the drive to "Power-
Up in Standby".
Does that mean it does not spin up until accessed?

Probably. Try it, and you'll know!

> Does that mean it does not spin up until accessed?

"Power-up in standby (PUIS) or power management 2 mode (PM2)(Western Digital specific) is a SATA or Parallel ATA (aka PATA) hard disk configuration which prevents the drive from automatic spinup when power is applied. The spinup occurs later by an ATA command, only when the disk is needed, to conserve electric power. PUIS requires corresponding BIOS support. If PM2 is enabled on the drive but not supported by the BIOS, the drive will not be detected by the system or detected as zero in size. PUIS is typically only supported on RAID Controllers."

Thanks for that Andreas,
It might make that feature useless to us.
I guess I do have to try it.
