On my Thinkcentre M55 there is actually a BIOS screen that warns of the SATA drive possibly taking several seconds to spin up, but on that machine, the drives are always detected on the first pass (perhaps owing to the delay at the SATA BIOS screen). On the T61 there is no special BIOS warning. I have not attempted to debug the problem beyond simply observing what happens when I try to boot the machine. IIRC there was no such trouble when running in legacy IDE mode. -sl
