Here's a question I keep forgetting to ask; is the 67meg drive self parking? I vaguely recall seeing a brochure for the Miniscribe drives that seemed to say something to that effect. ? Richard

Whether it does or not, the ATT documentation states in more than one place, that you should boot up the diagnostics disk and use the park heads option whenever you are going to move a machine. It doesn't (if I recall correctly) really talk too much about parking before a power down, but I would imagine it wouldn't be bad practice. -- "I've been trying for some time to Robert J.

Yes, but despite those warnings there was an addendum sheet included with version 3.51 (as shipped with my 3B1) that stated to disregard the message about using the diagnostic disk to park the heads - it said a normal shutdown from the UA was sufficient. ::::::::::::::::::::::::::::::::::::::::: :: Boyd Ostroff, Technical Director :: System Operator, "The CallBoard" :: Department of Theatre, SUNY Oswego :: - Serving the performing arts - :: Internet: ostroff@oswego.Oswego.EDU :: (315) 947-6414, 300/1200 baud, 8N1 :: Voice: (315) 341-2138 :: UUCP ...sunybcs!oswego!cboard!ostroff :::::::::::::::::::::::::::::::::::::::::

According to the 3.51 OS Technical Tips notes (separate sheets that came with the AT&T UNIX pc Owner's Manual) page 5 states: 4. Page 3-95. The disk heads on the model 3B1 do note need to be parked using the Diagnostic Disk. These disk heads are parked automatically when the shutdown command is used. Disk heads on model 7300 must be parked with the Diagnostic disk as described on page 3-95 of this manual. Therefore, the /etc/shutdown message is bogus on 3B1's and the hard disks are self-parking. -Lenny -- Paper-net: Lenny Tropiano | @-net: lenny@icus.UUCP ICUS Software Systems | !-net: ...att \ PO Box 1 | boulder \ Islip Terrace, NY 11752 | talcott !icus!lenny Vocal-net: (516) 582-5525 [work] | pacbell / (516) 968-8576 [home] | sbcs / Telex-net: 154232428 ICUS | Another-net: attmail!icus!lenny

He said yes, of course. He went on to say next time I shut down my machine to listen to the sound it makes, he assured me that was the sound of the heads retracting, and then parking. Robert

The 67 Meg drives (Miniscribe) have a self-parking feature. Using the diagnostics disk to park the heads is self-defeating. As soon as you power down, them heads is gonna park theyselves anyhow.

Yes, the "67MB" drive on the 3B1 is self-parking upon power down.

I vaguely recall seeing a brochure >|>for the Miniscribe drives that seemed to say something >|>to that effect. ? ALL Miniscribe 6xxx series drives self-park when the power is removed. The actuator is retracted and locked on the loss of power. In other words, if you've a Miniscribe full-height drive, it auto-parks when you turn off the power. The OS has nothing to do with it. AT&T's contention that the 'shutdown' command does this is incorrect, at least for the larger disks... This is also true for Seagate full-height 4xxx series drives, as well as the ST251's. It is *not* true for most garden-variety stepper-motor small drives (ex: ST225, etc). These need to be parked. -- Karl Denninger (ddsw1!karl) Data: (312) 566-8912, Voice: (312) 566-8910 Macro Computer Solutions, Inc. "Quality solutions at a fair price"

The addendum to the 3.51 System Software guide (extra 6 or 7 papers) states that if you have a disk that originally came in a 3B1, (NOT 7300!) your hard disk does not need to be parked.
