I worked on optical media players for years (Laserdisc, CD) and
sometimes a scratch or scratches in the right direction prevents wild
swings in the "tracking" signal from causing skips. Information is
sometimes not lost behind the scratch because of Cross Interleaved
Reed-Solomon code (CIRC) and other error tolerance schemes providing
placement diversity.

Sometimes test discs with natural flaws (like cleaning them with steel
wool) work even better than the ones with the intentionally fabricated
flaws especially when troubleshooting sled or lens (tracking and focus
signal) problems.

Busted!  :oD

I once had the "guts" of a CD player (made from parts of junkers)
hanging from a ceiling hook (like a "mobile"), and workng. Quite a
conversation piece. I eventually "found" a suitable cabinet for it. When
I was young, my mom was afraid to enter my bedroom with all the projects
involving tubes and wires in there.

I built push-pull power amps via 6L6's and my favourite tube was the 4CX1000K.

Additionally I built Zenith/Heatkits.  A 5MHz oscilliscope and a Colour Dot and
Bar
Generator (to adjust colour convergence on TV sets).

I never thought of a favorite tube - but I guess the reflex klystron,
the magnetron, and the travelling wave tube (radar and microwave). I
like the way circuits start to resemble tin cans and echo chambers in
the microwave region.

Nice. Heathkit's are cool - and useful.

Do you remember the "Magic Eye" tubes used in AV hardware to show signal
levels (like recording levels)?

I built a lot of Heath kit Z-89 computers

I do  :-)

I used them in capacitance checkers that used a bridge tuning circuit.  The
"Magic Eye"
would show a green phosphorous glow at 270 degrees and as you rotated the dial
and "tuned"
the bridge the "Magic Eye" would go to 360 degrees.  When it did, you read the
value on
the dial, used the multiplier, and that was the Capacitance value.

G-d, I miss that Zenith/HethKit store.  :-(

We had a ATT salvage yard around here when I was growing up - they would
dump entire switching stations, in entire cabinets, meters, cards,
relays, etc... Other companies would dump their hardware there too - a
few years later they would not let us salvage anything.... it was great
while it lasted.

My first gig in the Navy was setting up CPM machines that no-one else
knew how to use, had been sitting for a year+, and to think I use to
build them from scratch - Here I was, an E2 working in an E6 position
all because I could build and program computers.

Both the eye wedge style (on tuners for signal strength) and the linear
(mostly on magnetic tape recorders for audio level).

Okay, I've seen some awesome indicator tubes - some of my first computer
experiences involved "Nixie tubes", and I worked for years replacing
display tubes on high-end tuners (Sansui). Displays have come a long
way. I guess you notice that sort of thing more when you start out
interacting with a computer via an IBM teletype.

LOL, I still have a box of nixi tubes, they still work (or they did the
last time I checked). Do you remember the old 5x7 dot LED displays from
the HP 98437 "calculator" - had one with BASIC and math, thermal
printer, even a card reader and plotter....

After I got out of the service I had a 3B1 computer, while in the
service I had a Osborne 1, had a Commodore PET 2001 in the late 70's and
then a SX64 while I was in the Navy on a ship, the B128 prototype
directly from Commodore - still having wire-wrap sockets....

Man, those where the days, what we could do with 4K of RAM!

I thought the 4CX1000K was "neat" to say the least.  It even looked cool.
If I remember correctly it was a 1KW ceramic tetrode transmitter tube with
copper fins for
forced air cooling for up to 120MHz (?).

I used to love to rumage through an electronic's store's old crap they had in
the attic.
They had lots of phun tubes I used to play with and study.  Much Army surplus
from US Army
CECOM.

I played with and studied many tubes but I never played with GHz Klystrons &
Magnetrons.

HeathKits were phun.  Learned a lot by actually building electronic test
equipment.  Even
tried my hand at etching my own copper circuit boards.

I worked for a time at the Naval Radio Transmitting Facility in Dixon
Ca. - next door was the Voice Of America transmitter site. My roommate
(the one I helped with his Altair) and I went for a tour there. This was
using some very old (eyecatching) mercury rectifier tubes to supply a
walk-in FPA stage. 250 kilowatts into a 17db gain curtain antenna.

I'm sure that you would have enjoyed such a trip. :o)

I once had a laser transmitter tube (Siemens), but never hooked it up.
Good thing, I probably would have hurt myself with that one.

DEFINITELY.  :-)

Would have loved to see that.

Its a good thing you didn't play with the Siemens laser transmitter tube.
Probably would
have burned down the house :-)

Sometimes, depending on how deep the scratches are; yes...

I also have had success with polishing (or radial scratching).

I've seen this a lot; the malware appears to look at the size of the file.  
There are some older tools I can use, such as a copy of SpySweeper from about
3 years ago that most malware won't shut down, though they'll shut down more
recent versions.  

But try installing it in safe mode and you might have better success.  Also,
try rolling back the registry manually (copy and paste) to at least a week
before the infection was first noticed.

How can that be done ?

I usually have a reg copy handy, but this drive in only a couple months old,
after my old drive died a natural death after 3.5 years, and didn't get
around to backing the registry up yet.
