My own experience with Seagate drives has not been good!

A while back I bought 2x 400Gb drives from Maplin, it was a while before I
unpacked them so there's no chance of returning them.

The one I have used so far worked OK for about a month then had a read
access error while viewing a pdf, re-booting resulted in pretty much what
you describe.

With a bit of persevering I got the PC to boot normally without the dodgy
Seagate, then with a lot more I got it to start with the Seagate back on
again - but it started in blue screen/CHKDSK mode and trashed a load of
files before finally re-booting into Windows.

After copying the surviving data to another drive I ran Spinrite 6, on the
first run (takes a whole day!) it marked a large number of allocation units
as bad, on a second run there were no unrecoverable allocation units but the
report indicated a massive total of seek errors!

ISTR a couple of decades ago Amstrad sued Seagate because their unreliable
drives were giving the cheap crappy Amstrad PCs a bad name.

How I wish I'd not rushed to Maplin and bought the Seagates, a month later
they had 500Gb Hitachi's for about the same price.

Have you tried putting that drive on anywhere *else* WITH THE

Note that some drives have different jumper settings for
"master" and "master with slave present". The BIOS can
"hang" for quite a while (almost a minute) looking for a
slave that it *thinks* is there -- but isn't.

I tried the Seagate on another pc connected to the second channel. The pc

If the drive spins up but is not detected, then the fault is most
likely inside the HDA (head/disc assembly). However, I have seen cases
where a bad IDE cable produces the same symptom. That said, if you
decide to replace the circuit board, be prepared to transplant the
serial EEPROM (flash) chip from patient to donor. On newer models this
chip stores unique drive specific calibration data.

See the following article for help in identifying the components.

HDD from inside Main parts:
http://hddscan.com/doc/HDD_from_inside.html

The following article explains why drives have "adaptive" data.

HDD from inside: Tracks and Zones. How hard it can be?
http://hddscan.com/doc/HDD_Tracks_and_Zones.html

Essentially the reason is that no two heads are physically identical.
HD manufacturers try to fit as much data as possible onto each
platter. To do this, they take advantage of any head that performs
better than the average.

For example, some heads will have a better frequency response than
others, which means that you can cram more bits on each track. This
technique is called Variable Bits Per Inch (VBPI).

Giant magnetorestive (GMR) heads use a separate element for writing
and another for reading. The separation between these two components
varies from head to head. Once again manufacturers optimise data
density by implementing Variable Tracks Per Inch (VTPI).

Each HD therefore needs to be calibrated to account for VBPI and VTPI,
otherwise the drive doesn't know where to find the tracks, or the data
within the track. When a drive powers up, it needs to retrieve the
bulk of its firmware from a reserved area (System Area) on the
platters. If it can't read these data, then it clicks. This is what
usually happens after you swap a board without transferring the
calibration information.

How long ago? The drives will have a warranty with Maplin, but if the
shop staff act like the stupid berks they normally are, you should be
able to ship them back to Seagate. You can check warranty status on
their web site.

I'd think you have a bad cable, or you broke the drive.

BTW, you can't 'swap' the controller cards between drives, the NV ram
on the controller is programmed to the drive itself.

Yes! Exactly. That would have prevented the problem completely which was...

I've slid so many test drives in out of the drive bay that occasionally the
test slave drive doesn't go in exactly straight and clips the bottom of the
Seagate drive. After closer inspection of the Seagate controller board, I
found a capacitor hanging by one terminal, a zero ohm resistor which had a
cold solder joint, and another capacitor missing from the board. There were
just a couple of pc pads with only some leftover solder to show for it. All
these parts are very small smd components and that's why I missed it on the
first couple of go-rounds. Fortunately, I had another Seagate drive with the
same controller layout. I used it to supply the missing capacitor. Soldering
was not easy at all as I tried to hold the part in place with a tiny
screwdriver. The magnetic field from the drive must have transferred to the
capacitor (or my tools have been around too many speaker magnets) because
the screwdriver was totally useless in aligning it to the board. I wound up
using a wood stick from a broken off Q-tip to hold it in place.

Anyway, the drive boots fine now. Next step is to backup the drive. I get so
involved in backing up and restoring other people's data I've neglected
doing the same for myself.

Great info Franc. However I'm glad I didn't open the drive. That certainly
would have ruined it for good.

As it turns out, the drive suffered a "clipping" problem. See my post a few
messages after this one in response to Chris Oates.

#7 says it doesn't work OK with the Seagate drive.

I'd think you have a bad cable, or you broke the drive.

BTW, you can't 'swap' the controller cards between drives, the NV ram
on the controller is programmed to the drive itself.
Oh it's clear to me.
the first drive is the master to start with, second one as a slave
which he in stalled. The slave connects with the master.. There is
something seriously wrong with the slave, it has destroyed or rewritten
some vital parameters on the master drive. The controller on the master
needs to be corrected..
Also, a true electrical failure may existed on the failed drive that
has now shorted the once working drive, which was the primary (master)..


When testing drives, its always a good idea to boot from a external
device to get your test PC running. Put the test drive in as a master.
Don't have any other drives connected to that channel..

Get a USB caddy to mount the drive in.

Yes! Exactly. That would have prevented the problem completely which was...

I've slid so many test drives in out of the drive bay that occasionally the
test slave drive doesn't go in exactly straight and clips the bottom of the
Seagate drive. After closer inspection of the Seagate controller board, I
found a capacitor hanging by one terminal, a zero ohm resistor which had a
cold solder joint, and another capacitor missing from the board. There were
just a couple of pc pads with only some leftover solder to show for it. All
these parts are very small smd components and that's why I missed it on the
first couple of go-rounds. Fortunately, I had another Seagate drive with the
same controller layout. I used it to supply the missing capacitor. Soldering
was not easy at all as I tried to hold the part in place with a tiny
screwdriver. The magnetic field from the drive must have transferred to the
capacitor (or my tools have been around too many speaker magnets) because
the screwdriver was totally useless in aligning it to the board. I wound up
using a wood stick from a broken off Q-tip to hold it in place.

Anyway, the drive boots fine now. Next step is to backup the drive. I get so
involved in backing up and restoring other people's data I've neglected
doing the same for myself.

Thanks for your reply.

An amazing diagnostic and repair... I'm impressed you were able to
recover.

going into setup. If I remember correctly, immediately after removing
the test drive, I was able to get to the bios menu but it said no drive
was installed. I used the internal clear CMOS jumper to reset the bios
but the outcome was the same. Now, I am not even able to get that far.
If I put in any other drive, I am able to access the bios menu and the
drive is recognized correctly. I was not having any problems with the
drive before adding the test drive on the secondary IDE channel. I can
feel the motor humming when the machine is powered up. I've tried
switching between "cable select" and "master=on, slave =off," that
didn't help. There are no clicking or foreign noises. I was hoping to
purchase a used drive of the same model and swap out the controller
boards. My question is, how close of a match do these boards have to be?
So far I have found the same drive model number and firmware code, but a
different HDA p/n. Anyone have any luck doing a swap like this? Is there
some identifying data on the hard drive platters themselves that would
cause the drive to "disappear" like this? I did try the drive in another
pc. It gave a similar error, "Drive not detected," and asked if I wanted
to bypass the detection process.

Thanks for your reply.

WHEW what a read. Put a known good drive on the dead drive cable. If CMOS
enumerates it then the drive electronics are hosed and you can either
toss it, try to find an exact working drive and swap the control board or
send it off to a recovery service if it has data on it you can't do
without.

My own experience with Seagate drives has not been good!

A while back I bought 2x 400Gb drives from Maplin, it was a while before
I
unpacked them so there's no chance of returning them.


How long ago? The drives will have a warranty with Maplin, but if the shop
staff act like the stupid berks they normally are, you should be able to
ship them back to Seagate. You can check warranty status on their web
site.

More than a year had passed by the time I unpacked the first one, might have
been more than 2.

Do you mean what a good read or what a bad read? Do I have a career in store
as a technical writer? lol. Anyway, you were right about the electronics.
See my post from yesterday. A few of the smd parts on the pc board got
knocked off from sliding test drives into the tight fitting drive bay
underneath it. I happened to have had another Seagate drive to use for
parts and now all is well.

Thanks for your reply.

LOL Yes your description was very verbose. I'm glad you got a resolution
using the method described. However, I {think} drives have writable flash
memory that is used by the manufacturer to map things like engineering
tracks and the likes so the possibility may exist that you would end up
with slightly less capacity or some other anomaly by the swap. Of course
this is pure speculation on my part but it is born of reading something
in the past and may not apply to new(er) drives. I have done exactly the
same thing with and old Conner RLL drive many moons ago and it did work.
Back then before IDE appeared on the consumer shelf drives were horribly
expensive and anything one could do to salvage a drive was well worth the
effort.I can remember waiting hours, even days for Gibson Spinrite to try
to move data from damaged to good clusters and map those clusters out as
bad only to find out it stayed at 30% done for 30 hours

It was a mixed blessing how GRC Spinrite kept at it come what may until it
strained the data out of a trashed cluster.

It could have done with a "flogging a dead horse" button!
