Most DEC drives as shipped with DEC system do not spin up on power up (for sure not in the era of the RZ25). I recall that some DEC drives had a jumper to select spin up on power up but I don't think all of them did. I think they was also a mode page switch. I also recall that the 1542 BIOS had options to send the command to spin up on power up. Things to look at. A long time ago I ran DEC drives on FreeBSD 1.5/2.0 when I had easy access to them. So I ran into these problems. Doug A. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
