Just post another logfile after your changes.
I won't have any changes until I buy a new optical drive that can run in AHCI mode. I'll let you know.
The 1:10 delay is not AnyDVD scanning?
I don't think so, because the mid-screen popup and the Notification balloon both disappear after the first 1:10 or so. The drive keeps spinning for about 30-40 seconds of the next 1:10, but since I can nudge Windows into action during that time, it seems that the drive is just taking more time than usual to spin down. If I let it spin down completely, it will spin up again as Windows recognizes the disk. I'd suspect a problem with the drive, but it doesn't do that under Win7. I can only guess that Win10 operates a little differently, even though it uses the same driver.
