80 or 40 pin cables?

[dmanshead]

What would you use to hook your optical devices up to and why?

i use 40 pin...dont really know the difference,but everythings been ok untill now

[dmanshead]

I was using the 40 myself but when my computer boots up it gives me a message that no 80 pin connector cable is on my secondary, just started seeing this after i installed a BenQ DQ60.

All the IDE cables are 40 pin. Some have 40 wire (older) some have 80 wires. The 80 wire 40 pins are best.

Old worries me more than the number of conductors. Tests show a 5-10%
improvement with 80 conductor cables and dma 2 optical drives, but that may be old vs new.

now i understand it a bit more

[jm1647]

All the burners I have bought that came with IDE cables have been 40 pin 80 wire. The colors of the connectors on the 80 wire are (they ones I have gotten anyway) blue to the MB. Grey to the slave and black to the master. Looking at the 2 cables you can tell the difference quick by looking at the cable.

and people with dells still insist on using cable select

my dell doesn't use cable select. it's old and i've worked it over 1 or 2 times.

So what are the differences between master/slave and cs? I'm set cs. Would I notice an improvement? What are the benefits of master/slave? I asked once before and still didn't get a grip on it. I've never had an issue and figured "it ain't broke, don't fix it"

When you go to change anything, cable or drive(s), cable select is an accident waiting to happen, it's really obsolete. Drives get picky about
what's sharing with them, almost every dvd burner and pata hard drive come
jumpered master or slave(wd excepted/standalone master), not cable select.
You are supposed to have a special cable, I just replace to be safe.

A 40 pin cable can handle DMA2 with ease. You want 80 pins for your hard drives (DMA5). Chewy's old vs new is also relevant. But get 80 anyway!

Requirement: The 80-conductor cable was first defined with the original Ultra DMA modes 0, 1 and 2, covering transfer speeds up to 33.3 MB/s. The cable is considered "optional" for those modes. However, for any Ultra DMA modes above mode 2, the 80-conductor cable is mandatory.

The above was copied from here

When you open your case (at least once per year) after cleaning all the fans, cpu cooling fins, and removing all the dust.

This is a good excuse to remove the 40 pin, 40 leads and replace with the 40 pin, 80 lead cable to the primary and secondary IDE cables. Real cheap and worth the effort.

Future motheboards are looking at not even having IDE connections, just replacing with SATA connections. Which means all your hard drives and optical DVD units with have to be SATA compatable.

how can i tell if its 40/80 lead?
