Exactly, CompFreek. I meant it when I said "always". I know about the spindown times and I used Nero DriveSpeed with success with other drives. With 1620 it doesn't work. Also, hdparm under Linux clearly reports that setting the drive's standby time is impossible: "HDIO_DRIVE_CMD(setidle1) failed".
So, coulikof, in 1620's case any spindown value means nothing. If there's a disk inside, it will spin forever.
I will probably learn to appreciate this feature in time. As I said, the instant access to the disc is a nice thing, so is the ability to tell you've forgot a disc inside by the led being on. I wonder why it's not advertised more.
