Eric, I read through and understood all your comments about hard-disk power management, etc.
My problem is: I am not-interested in being "the one" who does power management. If DOS or the BIOS wants to save power thru putting disks into "stand-by" mode, let them do it. UIDE is a disk "I-O driver", not a power-management tool, and I desire to keep such things OUT of UIDE's logic! Re: handling disk drives which ARE in "stand-by" mode, if all I need to do is allow some more time for them to spin-up, that is relatively easy. UIDE's CD/DVD logic currently allows 7 secs. for spin-up and 3 seconds for track-to-track seeks, which I had forgotten -- I had not looked at that logic for almost 5 years! Assuming 7 seconds "should be long enough!" for a hard disk, as well, I can simply use that value as a timeout during disk I-O, not the current 400-msec timeout. Shall "experiment" re: this idea. Might cause some "confusion" among UIDE users, who will now see a 7-second delay in some error handling. But, if UIDE needs only a timeout change to handle "sleeping" hard disks, it might be worth updating only 1 byte in its "DoIO" subroutine! Jack R.
