 No, you haven't. In the PC world, Seagate is about as good as you
get. Apparently Ed Maurer up there is the one who's been
misinformed.

Brett must have missed the 100's of messages previously in this group
about failed, no-good, worthless 225's.  Seagate 225's are the only
hard drive that had a 40% DOA rate at the store I worked in, and many
of those that I told people to buy are now dead.

He must have also missed the comments in most of the latest Micro
Cornucopias, from various people telling stories of grief and lament,
based on Seagate's 225.

Many Seagate 225's have bad stepper motor controllers, which make it
difficult to read track 0 after a while.  This makes a disk sort
of hard to call reliable, huh??

Not to mention the ST251's that last about a year, then start refusing
to spin up...

My friend had 3 ST251's on his BBS...they were all about a year old, and 
they all started to have the same problem...on power up, they would refuse to
spin up, doing so only after he tapped them a few times, or gave the 
thing a little twist with his finger.  In my office, another ST251, about a
year old, has started failing in the same way.
 
So, what is the MTBF for an ST251, anyway?  :-)

No...you are misinformed.  For those of us who have actually had the
misfortune to use Seagate drives...as opposed to just read an article
in a magazine...the abysmal quality of Seagates is legendary.  There
has been no end of bandwidth on USENET devoted to peoples horror
stories after being fooled by the low prices into buying a Seagate.

If you're interested in my personal set of horror stories, send me
e-mail.  

Word of advice:  never take the word of a magazine...especially one as
		 devoted to advertising revenue as PC World...as
		 gospel.  You WILL get burned (particularly if they

  Well according to the Seagate prouct comparison sheet I have in front of
  me they rate the 251(and 225) with a MTBF of 35,000 and a service life
  (all of the 5 1/4's listed) of 5 years. Also of note is that they rate all
  of their 5 1/4' HH SCSI drives at 30,000 hours except for the 225N which
  is 35,000.

  I hope my 277N lasts ok.

 If the ST225 is all you can complain about, 1 drive of many, you
talking about a good company. My ST277R has lastest longest with
fewer problem than *ALL* the HD I've owned before.. miniscribes,
tandons, et al. 225 was a bad drive, I'll give you that, but don't
condemn the entire line because of one lemon.

Let me start off by saying that I don't have an ST225.  I do have an ST238
with an RLL controler, 30Mbytes, etc.  I have been using it almost everyday
for over 3 years now and have yet to have any problem with it.  I think
the misinformation may be between the drive and the company.

There's been a lot of "Seagate-Bashing" lately but the complaints
are mostly anecdotal - not statistical.  Does anyone have a REAL feel for
the relative reliability of these things?  I suspect it's possible to 
find a large number of dissatisfied Seagate users out there because of
the ENORMOUS numbers of those drives on PCs.  The price of Seagates seems
to be about $10/Mbyte - about the same as the "better" brands.  The rea-
son I'm curious is that I've used several Seagates in the past with lit-
tle or no problem but continue to hear horror stories - maybe only the
negatives reach the net.

I'm inclined to agree with you- people are always much more vocal when they're
dissatisfied with a product.  I've had my Seagate ST238 RLL drive for about
2 years.  It came with ZERO hard defects, and no soft errors have ever shown
up even after 2 years of relatively heavy use.  I have no complaints about it
at all.  Incidentally, the ST238 is based on 225 technology.  I wonder if the
changes for RLL control made it any more reliable?

If you really hate them that much, just ship 'em to me (I'll pay the
freight). Not only have I been running an ST225, but I have been running
it from an RLL controller! 

Besides, even if track 0 goes bad/can't be reached, a little creative
partitioning will take care of that problem toot sweet...

How true!  Seagate's reliability seems to show a roller-coaster effect. 
ST-225's are known to suffer from "track drift", where the alignment of the
heads slowly drift away from the original track positions, making even
freshly written sectors tough to read.  This problem is apparently shared
by virtually all drives that use stepper motors.  Voice coil drives don't
have this problem since the pre-recorded servo information allows the heads
to line up precisely over a track.  Even temperature sensitivity is reduced
because the platters expand and contract together to minimize mis-alignment.

A book on PC repairs and upgrades (quite new, the author wrote about DOS 4.0
and the 80386SX) that I bought recently made some serious suggestions against
the use of stepper-motor drives.  These units are almost always less than
~50 Mbytes.  I would say if they must be used, then run something like
Gibson Research's SpinRite every now and then to zero out the accumulated
track mis-alignment.  The horror stories I have heard from my friends alone
regarding the ST-225 had me thoroughly convinced.

On the other hand, Seagate's ST-4096 does appear to use better technology.
I had the opportunity to open up one such drive which died as a result of
having been dropped from a distance of several feet (I don't think any drive
would have survived that treatment).  The ST-4096 uses a linear voice coil
and sputtered thin-film media.  And at ~$530 a piece, it seems like a pretty
good deal.  I know of one person who has successfully squeezed almost 150 MB
off of this drive by using it with the Perstor PS180 controller.  This
Seagate does appear to be one of reasonably good quality.

Watch out for some of the older full-height Seagates, though.  I've seen
several ST-4051 units that refused to spin up when power is applied, unless
they are given some quick jerks to move the platters off their "dead-spot".
And who knows what kind of damage the surfaces might sustain with this kind
of "abuse"!

In case you haven't noticed, I'm into pushing MFM drives into higher 
capacities with Perstor and RLL controllers.  Does anyone care to share 
similar experiences?

Sorry for the long message, guys.  I got a bit carried away.

I've seen this same problem with nearly every ST-4051 we have in this area.
Leaving the drive on for long periods of time (i.e. overnight) seemed to 
increase the likelihood that the drive would freeze at the next power cycle.
Perhaps a better but move involved "un-freeze" method is to remove the
bottom controller board of the drive.  With the controller board off, the
bottom of the motor spindle can be manually rotated to un-freeze the drive.
This patch has always worked for me although a couple of times it had to be
applied twice.

Just the most basic precautions, Carl:  I think some installations suffer
from temperature problems, so make sure the drive (and controller) are 
adequately cooled - it'll extend the life of both electronic and mechan-
ical components.  Always park the heads before you power down (I know you
don't plan on moving the machine, but Murphy being Murphy, you'll have
to move it soon) head park programs are simple for the ST238 - some have
been posted here.  No matter how often you think you need to backup data,
back up twice as often.
There's no reason the drive shouldn't last a long time, given reasonable
care.

I owned a ST238R with Western Digital Controler (WD1002-27X) for about
two years.  I had no trouble with it.  It seemed to be very slow.
I purchased SPINRITE software and ended up changing the interleave
factor.  It seems to be a good drive for the money.

Having talked with the disk gurus at HP Greeley Division who know all about
this "stickion" problem (as they call it) with the ST-4051, here's the scoop:
for several months in early 1985 (when HP was using this drive in its products)
Seagate had a production problem which affected all units.  The spindle motor
would out-gas a sticky substance onto the inner tracks of the platters.  Since
power-off parks the heads on the innermost track, the heads come in contact
with this goo.  Eventually, the heads stick to the media, and the drive doesn't
spin up.  The trick of jerking the drive or manually turning the spindle motor
will usually free the heads, but there is a danger of ripping the heads off
the actuator.  Our maintenance group here in Loveland summarily replaced all
4051 drives they could find with newer units.  Later in 1985, the production
problem was fixed.

BTW: I'm using one of the (eventually-to-go-bad) ST-4051's in my home system
right now: got it REAL cheap at a scrap auction.  But I keep backups!

Andy,

The current PC World has a couple of pages on hard drives, the special
surface on the ST238R, and some interesting tricks to keep your drive 
under control.  They also explain some common sources of disk failures.

The ST238R that I installed last week also came with zero hard defects
and so far is purring and clicking happily away.  

I plan on some sensible backing up and on following the defensive
maintenance procedures outlined in the article.  

Of course, I'm the kind of guy that changes his car oil himself every 3,000 
miles, so I may be a bit more fussy than some folks :-).

Just a note on parking.  Seagate's manual says "All Seagate drives,
with the exception of the ST213, ST225, ST225N, and ST238R products,
have an automatic read/write head parking function at power-off."

I've had one for three years and another for one year, and had little
trouble.  I reformat them about once a year and defragment the drive by
hand about every six months.  One developed some bad spots at the end
of the disk but low-level format to mark them bad worked fine.  For
my controller (Adaptek 2070A, yes, that one), the optimal interleave
was 3:1 and it really speeded things up.

I'm using a brand new ST251-1 (about a month old) and seem to
have experience the problem of it not spinning up properly when I
turned it on.  I had to turn off the system then on again before
it would do anything.

Anyone got any suggestions?  Should I return it (I can't
reproduce the problem)?

That's a strange thing about Seagate drives, they never have many defects
recorded when the come from the factory.  This really makes me curious
about how well they test them.  Just about all of the Micropolis and
CDC (Imprimis) drives we have seen pass through our doors have multiple
defects listed, yet Seagates always appear to have less or none at all.
You can use Micropolis or CDC drives with RLL controllers with little
problems, yet the Seagates usually fail to perform to our satisfaction.
(Note: none of the drives mentioned are RLL rated)  The Seagate 4096
is Seagate's best drive, the half height models are best avoided if
financially feasable.  I will offer one other opinion, Seagate half
height drives are not the worst we have seen, Miniscribe gets the
award on pure garbage in the half height department.  I would never
trust my data to a drive that makes strange tinny sounding whirring
and clunking noises.

Regardless of the drive, a regular full back-up is always good measure.
A decent tape drive helps to insure that back-ups are done in timely
manner.

MORAL OF THE STORY:
-------------------

It is better to WAIT until you have an extra couple hundred dollars to
spend for a "REAL" disk drive than to gamble with a cheapie!
Replacing the drive once, or the inconvienience of loosing data far
offset the extra dollars of initial investment.  Disk drive prices have
been dropping lately, you can buy a decent drive for much less than you
could a year ago.
