I recall text fragments like
"Any device claiming compliance to ATA-3 or later as indicated in IDENTIFY DEVICE or IDENTIFY PACKET DEVICE data should properly release PDIAG- after a power-on or hardware reset upon receiving the first command or after 31 seconds have elapsed since the reset, whichever comes first."
that seem to imply that probing a nonexistent device may take 31 sec before one is allowed to conclude that there is nothing there.

(ide_wait_hwif_ready() used to wait 35 seconds)
