Time to switch the CD/DVD player--easy right?

[RayLopez99]

Symptoms: it will occasionally not show up in a Windows Explorer Win 7, modern hardware system.

It seems "weak" like it is underpowered, but power supply is adequate.

I saw the usual fixes on the net (update driver, play with Registry settings etc, etc) and none work.

What did work temporarily was to remove Daemon Tools software driver* but only temporarily.

Once in a while the drive shows up...then disappears again.

Replacing the hardware should be easy? Just plug the replacement to the same (Sata I think) mobo connection etc etc. Hardware should be built into Win 7? This is a "pirate" (Thai $5 copy) Windows 7 OS but I think the CD/DVD rom driver should be in the usual default places, whereever that is. Also "Seach Net for Updated Driver" does work here, so I shouldn't have a problem?

* CD drive not detected: Windows 7 fix

DAEMON Tools Lite is the culprit. It adds a software drive that simulates your actual "D" CD/DVD ROM drive and thus masks it. Remove Daemon Tools Lite on Windows 7 and the problem goes away. BTW I have nothing against Daemon Tools, and I use it on my other system, but am just reporting the facts.This system is Windows 7 SP1 on a modern multi-core machine.?

Test with another OS setup, to verify the hardware works.

Boot from a Linux OS on a USB stick, then test the optical drive.
While you can boot from a LiveCD, the USB stick may be easier
for you to arrange. (The optical drive is then free to be used
for read/write testing, as you wish.)

An OS with KDE as a Window Manager, may come with a copy
of K3B, which is a burner application for Linux.

I liked that one so much (the fact that it actually works),
I remastered a Ghome based distro, removed excess
files, and installed ~100MB of stuff for K3B and necessary KDE
libraries. That's how much better it works, than the non-working
burner application that originally came with the Gnome based distro.
I actually went to the trouble of incorporating it into
a LiveCD. (Some LiveCDs support "ToRAM=yes" as a boot command
line option, after which the LiveCD can be removed from the drive.
At least 1.5GB of RAM installed, is a recommendation for such a usage.
Running that with 1.0GB of RAM, and using 700MB for the CD storage
in RAM, is a little tight.)

Thanks Paul. I verified using a bootable CD that would not boot that the problem is the hardware, not the software. So I will swap out the old with a new DVD/CD Writer/Reader, a SATA connection and a power cable, right? Then upon bootup I think it should "self detect", no? I don't think I even need to play around with the BIOS. But anyway it's a doable done deal, and I don't anticipate many problems.

You got another SATA cable? Try it as well.

Also, download authentic Window$ 7 ISO from DigitalRiver! The one you
bought might have malware in it!

BTW, there is a Window$ 7 activation tool called Windows Loader.

You are really OCDC about the formatting thing for a top poster. You might
want to do a meds check with your doctor.

I assume this is a joke based on a previous thread in this group. Since it is unlikely a SATA cable will ever go bad.

I will try replacing the drive first, and if it does not work right I will then replace the SATA cable. ;-)

How wrong you are, sir.

SATA is a controlled impedance cable. To damage it, all you
have to do, is bend it until it kinks, distorting the dielectric
inside. While the dielectric for both (+) and (-) might be
affected equally, we don't know that in any given case.

SATA has some kind of CRC error check on the packets that
go back and forth on the cable. So at low background
error rates, you're protected (by retransmissions). But CRC
is not infallible, and eventually, data with errors could get through
undetected. The more beat up the cable is, the more likely
an error will get through.

Replacing a SATA cable, remains a valid diagnostic procedure.
And rather than being for the impedance/bending issue, it's
as much for the condition of the contacts on the end. Being
a wafer contact, the substrate can crack and give an intermittent
connection.

We made our first discover of hot plug capability, when a
poster came here, and reported he broke the connector off
his SATA drive. And by holding the cable up against the drive
just right, the drive was re-detected and he could finish
copying off the data before discarding the drive. We have a
history of ham-handed users, and "scientific" discovery
If you run out of ideas, change the cable. It might be a bad
connection.

First generation SATA cables, had no retention features, and
tended to fall off. Requiring users to press them back into
place occasionally. Now, a good SATA connector, has a metal
clamp on it, with tiny teeth, to help hold things in place.
The SATA committee designed this connector system, for
server backplanes, and could not have cared less, about
what their scheme would do for desktop users. It took
engineering backfill, on the supplier side, to fix this
in the second generation.

Occasionally, a SATA connector will rip right out of a motherboard.
Happens on the $50 motherboards, more than anything else.
You can tell as soon as you handle one of those, what's
going to happen to it. Again, more of a first generation
problem. The cheapskates are getting smarter now.

Good thing to know.

I have to agree that the SATA sockets and plugs (both power and data
ones) can be damaged easily if the manufacturers use low-quality
plastic. Also, plastic tend to become fragile as times by.

Users must also be careful when plugging and unplugging.
