I have an ST157N and its embedded SCSI controller seems to do its own auto-parking. Or you could call it "auto-lets-move-the-heads-and-spread-the-lubricant-around". The muscles in the disk get cramps from staying in one place for so long, so it has to get up an stretch a bit. :-) -- Joe Smith (408)922-6220 | SMTP: JMS@F74.TYMNET.COM or jms@gemini.tymnet.com McDonnell Douglas FSCO | UUCP: ...!{ames,pyramid}!oliveb!tymix!tardis!jms PO Box 49019, MS-D21 | PDP-10 support: My car's license plate is "POPJ P," San Jose, CA 95161-9019 | narrator.device: "I didn't say that, my Amiga did!"

Or you could call it This makes sense but why does it have to park every 4 or 5 minutes, even if I don't use it between parks ( if they are parks). This usually happens when I'm watching TV, which in my case is a VCR running into the 1080 (that makes a very good TV). As I said parking sounds like a reasonable explanation but it would seem that once it is parked it should stay parked, unless its' muscles do get lethargic and it needs to get up[ and wander around.

Still confused alittle. > Here's what I have noticed with my ST277N (and pre-Kronos A1000 CLTD controller, although not for much longer): After a write, there's a second or two before it flushes the buffer and closes the file which makes a little noise and flashes the light. A second or two after THAT, I always hear a tiny noise and a very brief flash, which I always assumed was the drive autoparking after a few seconds of non-use. But about a week ago, for the first time, the drive started doing stuff by itself when I was **not** accessing it. Since then it has stopped. I'm begining to think this might be some sort of virus.

Those aren't parks, they're track 0 reseeks (otherwise known as "recalibrates") As to why they happen...I dunno. All SCSI drives do it, some more than others. Just ignore it.

Well, (embarrased :-), it turns out that I had selected the "Continuous Spell Checking" option available in the new ProWrite without knowing what it did. All the noises (and the occasional BEEPS that I'd forgotten about until last night) were due to the spell checker accessing the dictionary and beeping at me when I goofed up a word.
