Nice. I was thinking more of the 'brand name' pricing, 10 or more times

You can use MHDD to test each sector:
http://hddguru.com/software/2005.10.02-MHDD/

AIUI, MHDD measures the time required to retrieve data from each block
of sectors. Any bad or weak sector will require one or more retries.
Each retry requires an additional revolution. At the end of the test
MHDD reports the number of 5ms, 15ms, 50ms, 150ms, 500ms and >500ms
blocks.

Here is a screenshot:
http://www.techmaniacs.net/files/tank_mhdd/mhdd_3.jpg

MHDD Documentation:
http://www.bandwidthco.com/whitepapers/compforensics/danalysis/MHDD%20Manual.pdf

EZ-bios is a disk drive overlay (DDO) which loads a small TSR program
into memory to allow a PC to overcome lack of BIOS support for LBA
mode. It was used to overcome BIOS limitations such as 528MB and
28-bit LBA (128GiB / 137GB).

EZ-bios works by overwriting the boot code in sector 0 of your HD with
its own MBR code. The remainder of the TSR code is stored within track
0.

I suspect that by restoring track 0, you actually overwrote the
EZ-bios code, which would have left you where you started.

The first one I owned had been a neighbor's that got blown up when
their incoming power lost the
nuetra at about age 3 - I replaced the PSU and the modem and used it
for another 3 years, Prior to it failing I'd noticed that some of the
caps on the MB were starting to bulge, and about six months or so
later it finally just wouldn't start one day. I'm glad to hear that
about the cd drives, I've got plenty of spares, I think even a burner
or two. Floppies in working condition are becoming much less
prevalent these days (my source always being the scrapyard, of
course:)

Well, I had several browser windows open and of a sudden the bowser
was stuck viewing the last one I'd been looking at - the mouse cursor
would still move around as it should but clicking on stuff had no
effect. Couldn't close any browser windows, couldn't start up any
other programs, couldn't shutdown the machine, except by pushing and
holding down the power button.

I haven't tried anything newer than 9.10, after I tried and failed to
figure how to get my modem working with it I went back to 8.04, which
seems much more intuitive to me.

Thanks, I'll have to see if I can get this SmartMonTools in 8.04.

Thanks for the explanation - so, I guess maybe some part of the info
on the drive was corrupted and I just basically refreshed things -
wonder if I should try installing EZ-bios again (just kidding, at
least while it's still working).

HP's used Bestec too? damn, that's too bad. Back in the eighties when
I worked on medical gear it seemed that HP's equipment was some of the
most robust (but of course, usually more expensive, too).

That was what is now Agilent. <www.agilent.com>

I own a 2005 eMachine, 2.0 ghz AMD Athalon64. It's now a Windows 7
machine and does its job flawlessly. Just like any other brand you need
to know what you are buying within the brand name. Being semi-retired
from the IT world now since 2008 I've seen plenty of junk out there
with Compac, HP, Sony, Toshiba badges on them. One thing you need to
understand is not many if any make 100% of their own components. So you
should not make global statements condemning the badge name without this
knowledge.

Geez you've just described about every computer out there.

2005 emachines T6216

Original power supply, Check!
Original mainboard, Check!
Original fans, Check!

LiteOn DVDRW failed year number 2. So did it's LiteOn replacement last
year.

Now have 16x16 Pioneer DVRW I bought in 2004. Still works well.

Moral of story, if you buy cheap stuff it will fail. Too bad that's
pretty much what you will find OEM-wise in this throw-away world.

Basically, the operating system got lost. That could be anything. Bad
motherboard, flakey IDE device, flakey plug in card, or even a bad
keyboard/mouse can hang the machine. However, it also can be a bad
sector on the HD. If you can get it to boot, try scanning the HD for
bad sectors and disallocating them. Then, keep track of the number of
bad sectors on the drive. Any increase, and it's eWaste.

What's a modem? Is that like dialup? I use those when desperate or

I had someone bragging about how much better his HP computer was,
than the eMachines computer sitting by my bench. I opened both. They
were both shipped with the same motherboard and power supply. The same
brand of CD-ROM drive and amount of RAM. Both had a 3.5" floppy drive.
Neither were cheap crap. He paid over twice the price of the emachines
computer for the same hardware.

I've yet to buy new, so I'm always stuck with whatever is already
there. However, it always cheers me to find inside a MB made by Intel
and a PSU with a name like Astec or Antec, or even John Deere, I've
had pretty good
service out those.

I bought an LG dvd burner a couple years ago from a former IT guy and
it is really phenomenal at reading dvds even when they're covered with
finger prints and scratches (like a lot of the ones at the local
library have), whereas, none of my previous burners (grand total of 2)
would be able to read 'em, at least not error free.

I had pretty good service with a T1742 that a neighbor gave me, it had
an Intel MB, and didn't have a Bestec PSU.
The 3 I found at the scrapyard all had failed Bestec PSU's, which
became notorious for not having a crowbar circuit to shut down the
outputs if they went over-voltage. Maybe they started using a better
PSU, the last blown up one I found was a T2862 or something like that,
I suspect a few years older than your 2005 model.

Sorry for that.
My TrendMicro took care of all that for me.

Can't blame them for trying to raise revenue, I guess. One would think,
though, that they'd turn it down a notch or two so as not to chase
people away. Or at least have dancing bears and cute puppies! ;-)

I believe the outputs are 75 ohm impedance,a coax type transmission
line,that you can't drive parallel multiple 75 ohm loads.
It's not a matter of "fan-out".

Now if you had 75ohm loop-thru inputs like many professional video
units,then you just terminate the end unit in 75 ohms,and it would all work
fine.

You cannot make that assumption without a scope which unfortunately
you don't have. I'm only guessing but I bet your video has bad low
frequency tilt which shows of as the 'DC' of the back porch wandering
all over the place. Cause: bad capacitors somewhere in the video
chain. IIRC the Gennum chip includes clamps to guarantee sampling at
50% of the sync pulse meaning it's more tolerant of poor video. The
scope would tell all.

Ok, thanks.Sadly the video (R,G,B ground + SYNC) is from arcade videogame
pcb, so I assume they have all poor video signal???
I 'd wan to try the Gennum GS4981 but it seems unfindable...

I believe JPEG/MPEG uses eigencovariance to transform the image to the
coordinate system that requires the least possible storage, so that
should already take care of the frame of reference. I suspect if you
can get a search engine to just notice were in the JPEG this is
located, it can find similar images. SOme of this work resulted from
Kalman, Dhrymes & Los working on the SDI identification problem in the
late 1980s.

I think many Sony's have the same/similar blink codes.
Search for '"Sony blink codes"'.

E.g., no vertical deflection

Supposed to be there to keep damp/condensation out but over 20 years or so
does the opposite. The waxy/jelly type coating (not the epoxy potting stuff)
breaks down to an oily film that is probably hygroscopic - plenty of green
copper carbonate and rotted IC pins. Gets inside chips capilliary-wise and
rots them internally as well. Anyone happen to know what this oily breakdown
product is chemically?

That coating is probably the silicone-based conformal coating, but I don't
know what mechanism degrades the coating. During the late 70s through
mid-90s, I serviced military equipment. Much of the stuff built in the 80s
and later was sealed with the silicone-based coating, but I never saw any
oily degradation. Exposure to salt water will cause the green corrosion
that you're seeing.
Could it be that the circuitry that you're experiencing the problem with was
incompletely coated, or had the coating scuffed off the IC pins? That would
have exposed the bare metal of the circuitry, leaving it unprotected and
susceptible to corrosion.
When the tip of the IC pin starts to corrode, it's just a matter of time
before the corrosion starts to creep under the coating.
