Yes, I know. All my cables are color coded like you said.

You may know :), but unfortunately you completely fail to show your knowledge :w00t: , in the sense that you haven't (yet) found a way to properly communicate your experiments. :ph34r:

Why don't you like cable select? And why is my IDE ports so fussy?

Because they tend to NEVER work properly/because it's not just your motherboard IDE ports (or BIOS) that are particularly fussy.
Thus DO NOT use Cable Select, in most cases it resolves to a vain attempt.

ALL THESE make little of NO sense:

Double cable set to CS and CS; Windows won't boot.
Single cable set to M; works.
Double cable set to Master with slave present (Western Digital) and slave; works but DVD burner is not detected in Windows.

Examples of something I (and I guess I am not the only one complòetely failing to make head or tail of yourt reports) can understand:

Device: Hard disk
Connected to: IDE port 0
Jumpers on device: set to Master
Cable used: single
Connector colour connected to motherboard: Blue
Connector colour connected to device: Black


Quote

Device: CD/DVD
Connected to: IDE port 1
Jumpers on device: set to Master

Connector colour connected to motherboard: Blue
Connector colour connected to device: Black


or:

Device: Hard disk

In other words, these two IDE cable configurations are the only ones that seem to fully or partially work:

Device: Hard disk
Connected to: IDE channel 0
Jumpers on device: Master or Single (WD)
Cable used: Single
Connector colour connected to motherboard: Blue
Connector colour connected to device: Black
Result: Works

=====================

Device: Hard disk
Connected to: IDE channel 0
Jumpers on device: Master w/ slave present (WD)
Cable used: Double
Connector colour connected to motherboard: Blue
Connector colour connected to device: Gray (doesn't matter)

Device: DVD burner
Connected to: IDE channel 0
Jumpers on device: Slave
Cable used: Double
Connector colour connected to motherboard: Blue
Connector colour connected to device: Black (doesn't matter)
Result: Works but DVD burner is not detected in Windows

Note: both devices are detected in BIOS.

Yes, it DOES matter! (now that we know WHAT you are using and HOW you've been connecting)

3-connector 80-conductor cable NOT USING "CS"!!!
Blue=MoBo
(end, REGARDLESS of color - or maybe BLACK?)=Master (HDD)
(center, REGARDLESS of color - or maybe GREY?)=Slave (DVD)

End is ALWAYS "Master", Center is ALWAYS "Slave" - just like 40-conductor! The only "magic" is the BLUE goes to MoBo!

From jaclaz' link (AND HE SAID IT TOO!)

Quote

Blue: The blue connector attaches to the host (motherboard or controller).
Gray: The gray connector is in the middle of the cable, and goes to any slave (device 1) drive if present on the channel.
Black: The black connector is at the opposite end from the host connector and goes to the master drive (device 0), or a single drive if only one is used.
PLEASE, get with the program!

This MoBo is WAY too new to bother with CS, of which OLD MoBo's would sometimes "recommend" it OR the junky OLD CD/DVD would "recommend" it. And, as stated, CS is many times unreliable (MY "last resort").

P.S. Some "genius BIOS" is perfectly happy with "detecting" even though WRONG!

Huh? I just read an article from a credible source yesterday that said it doesn't matter which connector you use for master and slave. All that matters is the jumpers are set correctly. This BIOS is from 2004. I've never had a problem with Cable Select in 8 years, which was the original jumper settings on the hard disk, CD-ROM and DVD burner. Let me try to find the article again and share it with you....

Found it.
It does not matter which connector is used for master or slave in a standard IDE setup. However, when using Ultra DMA in a single-drive configuration you should use the end connector because of electrical signaling issues.

But let's assume you're right and they're wrong. It still doesn't explain why all those other IDE cable configurations failed.

From my previously referenced link - http://en.wikipedia....i/Parallel_ATA[

Quote

Parallel ATA interface
[...]
Though the number of wires doubled, the number of connector pins and the pinout remain the same as 40-conductor cables, and the external appearance of the connectors is identical. Internally the connectors are different; the connectors for the 80-wire cable connect a larger number of ground wires to a smaller number of ground pins, while the connectors for the 40-wire cable connect ground wires to ground pins one-for-one. 80-wire cables usually come with three differently colored connectors (blue, black, and gray for controller, master drive, and slave drive respectively) as opposed to uniformly colored 40-wire cable's connectors (commonly all gray). The gray connector on 80-conductor cables has pin 28 CSEL not connected, making it the slave position for drives configured cable select.
[...]
Pin 20
In the ATA standard pin 20 is defined as (mechanical) key and is not used. This socket on the female connector is often obstructed, requiring pin 20 to be omitted from the male cable or drive connector, making it impossible to plug it in the wrong way round; a male connector with pin 20 present cannot be used. However, some flash memory drives can use pin 20 as VCC_in to power the drive without requiring a special power cable; this feature can only be used if the equipment supports this use of pin 20.
Pin 28
Pin 28 of the gray (slave/middle) connector of an 80 conductor cable is not attached to any conductor of the cable. It is attached normally on the black (master drive end) and blue (motherboard end) connectors.
Pin 34
Pin 34 is connected to ground inside the blue connector of an 80 conductor cable but not attached to any conductor of the cable. It is attached normally on the gray and black connectors. See page 315 of.
[...]

Differences between connectors on 80-conductor cables
[...]
Note the connections to the common ground bus from sockets 2 (top left), 19 (center bottom row), 22, 24, 26, 30, and 40 on all connectors. Also note (enlarged detail, bottom, looking from the opposite side of the connector) that socket 34 of the blue connector does not contact any conductor but unlike socket 34 of the other two connectors, it does connect to the common ground bus. On the gray connector, note that socket 28 is completely missing, so that pin 28 of the drive attached to the gray connector will be open. On the black connector, sockets 28 and 34 are completely normal, so that pins 28 and 34 of the drive attached to the black connector will be connected to the cable. Pin 28 of the black drive reaches pin 28 of the host receptacle but not pin 28 of the gray drive, while pin 34 of the black drive reaches pin 34 of the gray drive but not pin 34 of the host. Instead, pin 34 of the host is grounded.

The standard dictates color-coded connectors for easy identification by both installer and cable maker. All three connectors are different from one another. The blue (host) connector has the socket for pin 34 connected to ground inside the connector but not attached to any conductor of the cable. Since the old 40 conductor cables do not ground pin 34, the presence of a ground connection indicates that an 80 conductor cable is installed. The wire for pin 34 is attached normally on the other types and is not grounded. Installing the cable backwards (with the black connector on the system board, the blue connector on the remote device and the gray connector on the center device) will ground pin 34 of the remote device and connect host pin 34 through to pin 34 of the center device. The gray center connector omits the connection to pin 28 but connects pin 34 normally, while the black end connector connects both pins 28 and 34 normally.

Multiple devices on a cable

If two devices are attached to a single cable, one must be designated as device 0 (commonly referred to as master) and the other as device 1 (slave). This distinction is necessary to allow both drives to share the cable without conflict. The master drive is the drive that usually appears "first" to the computer's BIOS and/or operating system. On old BIOSes (Intel 486 era and older), the drives are often referred to by the BIOS as "C" for the master and "D" for the slave following the way DOS would refer to the active primary partitions on each.
The mode that a drive must use is often set by a jumper setting on the drive itself, which must be manually set to master or slave. If there is a single device on a cable, it should be configured as master. However, some hard drives have a special setting called single for this configuration (Western Digital, in particular). Also, depending on the hardware and software available, a single drive on a cable will often work reliably even though configured as the slave drive (most often seen where a CD ROM has a channel to itself).


Yes, the article also talks about CS, and yes, it is supposed to work. But I, and apparently jaclaz and submix8c, have had enough problems with it over the years, even with hardware that was specified to use CS, that I do not trust it. Problem I had were only solved by not using CS. No reason why was ever found by me or explained by the manufacturer. And you are trying to fix your problem, right? So why not do what has proven most reliable? Once working, if you want to go back and switch the jumpers on everything back to CS you can, and at that point it might work. But in the meantime, please eliminate as many possible trouble points as possible. It will make our, and your, job easier.

Cheers and Regards

Besides the fact that you failed to provide a link to your "reputable source", no actual problem, it's most probably this one :whistle: :
http://www.techpower...ticles/other/52


I will re-state the whole base idea.
  • You come here with a problem.
  • You ask for suggestions on how to solve the problem. <- Mind you that the sheer fact that you are asking for these suggestions here implies, that you are NOT able to solve the problem yourself AND that you trust the knowledge/experience of other members to be superior than your own one.
  • You are given a suggestion and some links to read that are by definition the most reputable/reliable ones available. If you prefer, by definition it is assumed that we are right and you are wrong (if and when doing anything not suggested)
  • These links tell you to connect a Master to Black (end), a Slave to Gray (middle) and the motherboard to Blue with 80 wires cables, going into even the smallest details, including pinouts, history of the interface and what not.
  • You would then be supposed to just §@ç#ing jumper and connect the drives as explained in the given links.


What you do INSTEAD? :w00t:
You insist on connecting the cables "casually" and find a "reputable" source that is much more vague than the given one (and it is clearly referring in the "main" part to the 40 wires cable), and that you ADDITIONALLY FAIL to READ accurately.
Here is the part that you completely missed:

Quote

The cable select feature was much improved with the introduction of 80-conductor Ultra DMA cables. The key changes were that the master connector has been moved to the end of the cable, putting the slave in the middle and all cables must support cable select now. You should be aware that if you swap an old 40-conductor cable select cable with an 80-conductor Ultra DMA cable your drive positions will swap logical positions, so you will have to change the order in which your drives connect to the cable.

No, no, NO.
40 wires cables: one end to motherboard, other end to slave, middle master.
80 wires cable: Blue end to motherboard, other end Black to master, middle Gray slave.
You know, like in the above:

or in:
http://www.msfn.org/...38#entry1023838

Quote

In case of cable select, often the Slave/Master are INVERTED when compared to the 80 Wire cables.


To re-cap:
  • With 40 wires cable in case of cable select the end is slave, the middle is master and the "further" end goes to the motherboard (ONLY on 40 wires cables the three are interchangeable if you don't use cable select though in practice when you mount drives in a traditional cabinet it will come "natural" to connect the lower hard disk to the middle connector and the higher CD/DVD drive to the end one and the motherboard to the further end)
  • With 80 wires cable in case of cable select the Black end is master, the Gray middle is slave, the Blue end goes to the motherboard. (even if you do not use cable select you should NOT change these connections, you can actually exchange Black with Gray BUT it is very likely you will have signal issues as current disk drives in use are using ATA 5 or 6 which use DMA modes 3 or 4 times faster than what originally prompted for use of the 80 connector cable with the master device on the end)

In practice, initially fake :w00t: that you are setting up a cable select system and connect connectors as per specs :yes: , then do not trust the devices :no: , nor the cable, nor the BIOS, nor anything else but the jumpers of the devices and set anyway the jumpers properly. ;)

Also, since I don't think it is mentioned... PATA cables have a maximum length of 18 inches (457 mm) but you can actually get longer ones. Make sure that your PATA cable is the appropriate length as well.

Oh, yes, it is mentioned alright in the given links:
http://www.pcguide.c.../conf_Cable.htm

Quote

The main issue is the length of the cable. The longer the cable, the more the chance of data corruption due to interference on the cable and uneven signal propagation, and therefore, it is often recommended that the cable be kept as short as possible. According to the ATA standards, the official maximum length is 18 inches, but if you suspect problems with your hard disk you may find that a shorter cable will eliminate them. Sometimes moving where the disks are physically installed in the system case will let you use a shorter cable.

Warning: There are companies that sell 24" and even 36" IDE cables. They are not recommended because they can lead to data corruption and other problems. Many people use these with success, but many people do a lot of things they shouldn't and get away with it. :^)

Note also that the 18" length restriction associated with the original 40-conductor cable applies to this variation as well.

18"=457.2 mm

@ jaclaz

Then why does an 80-wire one-device cable with the blue end connected to the motherboard and the other black end connected to the hard disk that's jumpered as Master or Single (WD) on IDE channel 0, and another 80-wire one-device cable with the blue end connected to the motherboard and the other black end connected to the DVD burner that's jumpered as Master on IDE channel 1 FAIL? The BIOS doesn't detect either the hard disk or the DVD burner with this configuration.

Yes, that's correct. My hard disk sits below my DVD burner, which is why I'm trying to use an 80-wire two-device cable with the blue end connected to the motherboard, the gray connector connected to my hard disk set as Master w/ Slave Present, and the black connector connected to my DVD burner set as Slave. Both the hard disk and DVD burner are detected by the BIOS, the hard disk works, but Windows doesn't detect the DVD burner.

How would you set this up using the least amount of cables to increase airflow?

Who knows?
Now that we have found a "common language" to exchange ideas and reports, it is time to troubleshoot

Test #1
  • FORGET the hard disk
  • Connect the CD/DVD drive (to the black connector AND jumpered as "Master") with a "single" cable to IDE0 (the blue side to the motherboard)


Does the BIOS see the optical drive?

Test #2
  • FORGET the hard disk
  • Connect the CD/DVD drive (to the black connector AND jumpered as "Master") with a "single" cable to IDE1 (the blue side to the motherboard) using the SAME cable used in test 1


Does the BIOS see the optical drive?

Test #3
  • FORGET the CD/DVD drive
  • Connect the hard disk (to the black connector AND jumpered as "Master/single") with a "single" cable to IDE0 (the blue side to the motherboard) using the SAME cable used in tests 1 and 2


Does the BIOS see the hard disk?

Test #4
  • FORGET the CD/DVD drive
  • Connect the hard disk (to the black connector AND jumpered as "Master/single") with a "single" cable to IDE1 (the blue side to the motherboard) using the SAME cable used in tests 1,2 and 3


Does the BIOS see the hard disk?

BWAHAHAH!!!! Functional Cable Isolation... Good call!

Quote

Who knows?
FYI - per the PCGUIDE link - maybe not so true?
From WDC (re: 40-conductor)
http://wdc.custhelp....the-system-bios

Quote

If you are using an Ultra ATA cable (80-conductor) make sure that the Master or Single drive is on the black end connector. Connect any Slave device present to the gray middle connector. Finally, the blue end connector should be connected to the motherboard or EIDE controller card. If you are using a standard 40-conductor data cable, connect the Master device to one end, the Slave to the middle and the other end to the motherboard.
Jumpers

Quote

If there are two drives on the data cable, one must be Master and one designated as Slave. If the drive is the only device on the cable, it should be jumpered as a Single drive, NOT a Master.
Single/Master(NoSlave)=NoJumper / Master(+Slave)=Jumper <-WD only(?)

You might want to check the Jumper Specs on that (unnamed) DVD Drive too...

More on 40-conductor / 80-conductor / CS
http://pinouts.ru/HD...al_pinout.shtml
http://unixwiz.net/t...ble-select.html

To throw fire onto the "position" on 40-conductor (pcguide link)

Quote

Making matters worse, the 40-conductor IDE/ATA cable select cables have the "master connector" as the middle device and the "slave connector" as the device at the end of the cable, farthest from the host.
I have 40-conductor Non-CableSelect cables. In addition, I have no problem connecting per WDC.

Quote

For signaling reasons, it's best to put a single drive at the end of a cable, not put it in the middle leaving a "stub" of wire hanging off the end of the channel. But if you do this, that single drive sets itself as a slave with no master, a technically illegal configuration.
Still referring to CableSelect cables and PROBABLY when using the Jumpers in CS-mode. Strange (or not) that many OLDER CD/DVD-Drives RECOMMEND CS on Channel-1 on the END of the 40-conductor Cable.

I'm only KIND OF disputing the "position" of Devices when using Fixed (non-CS) Jumpered Mas/Slv configurations.

No, you are seemingly having problems in reading/understanding what is written.

There exist (in 40 wires cable) BOTH Cable Select Enabled and "plain" NON Cable Select ones, on the 40 wires CSE cables the Slave is at the end of the cable .

The 80 wires are all (or should be all) Cable Select Enabled and the Slave is in the middle.

On *any* bus of *any*kind (and not only PC/Computer related) having an end of a cable "free" with nothing connected to it is NOT smart and it is a possible source of trouble.

Do you remember the good ol' SCSI bus and it's "terminators"?

Still referring to CableSelect cables and PROBABLY when using the Jumpers in CS-mode. Strange (or not) that many OLDER CD/DVD-Drives RECOMMEND CS on Channel-1 on the END of the 40-conductor Cable.

No, you are seemingly having problems in reading/understanding what is written.

There exist (in 40 wires cable) BOTH Cable Select Enabled and "plain" NON Cable Select ones, on the 40 wires CSE cables the Slave is at the end of the cable .

The 80 wires are all (or should be all) Cable Select Enabled and the Slave is in the middle.

On *any* bus of *any*kind (and not only PC/Computer related) having an end of a cable "free" with nothing connected to it is NOT smart and it is a possible source of trouble.

Do you remember the good ol' SCSI bus and it's "terminators"?

@ jaclaz
I'm waiting for a package in the mail of cable ties. Once it arrives, I'll shut down my computer and start isolating IDE cables. But first, I'm simply going to try changing the jumpers to Slave on the hard disk and Master on the DVD burner, just to see if this makes a difference. A hard disk can be a Slave to a DVD burner that is seldom used without issue, right?

Even if it "can" be, it is not the best practice. Are you sure your cable is not long enough to be able to connect the DVD and HDD to the cable in the correct positions? Just because the DVD is located "above" the HDD doesn't mean that the cable can't be bent/twisted/folded in order to get it into the right position. If the cable is long enough for the middle/slave connector to reach the DVD, then you should be able to make it work.

Cheers and Regards

@jaclaz -

Well, that's the reason I said I "kind of" dispute the assertions made in said article about 40-connector MASTER=MIDDLE and SLAVE=END, since I've always used (per WDC as well) MASTER=END regardless of SLAVE=MIDDLE attached or not.

You see, I'm reading CONFLICTING info on "where to connect" on (aka) 40-wire MAS/SLV. As in the "good old days" the Jumper sets Device0-MAS and Device1-SLV (AFAIK).

:unsure: Maybe the 40-wire ones I've been using are Non-CSE (IOW, CS should NOT be used on the Devices and won't work)? Guess I'd better check the box contents and start marking. Either they are "cut" somewhere or disconnected on that pin ( ref http://unixwiz.net/t...ble-select.html ). Interesting that said article links back to pcguide. Hence the Non-CSE vs CSE misunderstanding (position of device) in relation to Jumpered-Not-CSE. Am I making sense?

Yes, SCSI Terminators - have an old HP NetServer sitting here gathering dust. And the could care less "where connected" and the Jumpers set the SCSI-ID.

The IDE cable is long enough. I can't twist it to make it so the HDD is on the end Master connector. I'm going to try my idea and just see if it brings back the DVD burner in Windows. What's funny is the BIOS detects it, but Windows is blind to it.

Good luck, but trust me, if you can reach from the motherboard to the DVD with the middle connector, and you can reach from the DVD to the HDD with the length of cable from the middle to the end connector, I'm 95% sure that it can be folded/flipped/twisted to make it work. I've wrestled with many of them over the years and have always succeeded. Try putting it together in reverse order. In other words, start the connection process by connecting the end connector to the HDD, then connect the middle connector to the DVD, then connect to the motherboard. A way you can experiment to see it this would even make a difference anyway is to just let the HDD temporarily hang from the cable, or prop it up with cardboard, just long enough to boot and see what Windows thinks. If the cable is hooked up correctly, and the BIOS detects it, and Windows still doesn't, then there is something else wrong with your Windows install.

Cheers and Regards

It turns out the problem wasn't the BIOS or IDE cables. I forgot to set the Local Bus IDE Adapter BIOS setting from Both to Primary. Using the two-device 80-wire IDE cable with the hard disk set to Master w/ Slave Present on the gray connector and the DVD burner set to Slave on the black connector, the BIOS and Windows detect the hard disk and DVD burner. Yes, I know the gray connector is supposed to be used for the slave device and the black for master, but the cable doesn't accommodate this setup and it's not causing a problem. Also, I restored my audio by jumpering the motherboard's front audio pins. I also restored my DVD burner in Windows by readjusting a few settings in Device Manager under the IDE channels. See, I only enable what I use on my computer, and after years of not changing it, I sometimes forget.

I do have a new concern, however. I noticed that the black teeth on one of the front USB ports to this new case looks damaged. There's a metal spot showing. The port worked fine in testing, but could this cause device damage, or is it only a cosmetic factory defect?

Makes no sense and I can't find anything indicating what those settings mean (regardless of the fact I SAID that color mattered IF USING CSEL).

As was already found. Glad you tried it and it worked. FP Connector is a separate issue.

Yes, too bad you didn't notice that BIOS setting before and the associated Device Manager stuff. Also too bad we have wasted a LOT of time on your "problems".

"BLACK TEETH"??? "METAL SPOT"??? What's THAT? Take a pic and upload it. That ALSO makes no sense! My Connectors have NO "BLACK TEETH" AFAICT... Another Goose Chase?

Sub, I'm referring to the black plastic horizontal strip inside a USB 2.0 type-A receptacle. A piece of the black coating is worn and appears a clear or silver color. My question is could this cause device damage, or is it only a cosmetic factory defect?

(sigh...) Inside MINE is a "vertical" (since mine is obviously Up-Down instead of Left-Right - YOU GAVE NO PHOTO IMAGE) Black Strip with FOUR contacts and on the OPPOSITE side there are TWO "contacts" that MAY be (and obviously ARE) for the Shield/CaseGround. See this Pinout (both Male and Female) and this Mobo Pinout? I have NO CLUE what you're talking about...

P-I-C-T-U-R-E!!!
