Do these cables have a male and female end then? One that has the pins to plug into the mobo cable and then one female end (without pins) that goes into the hard drive?

Yes kamper speaks the truth here. I have two rounded cables in my rig and both of them are good. Your cables might come with a label on them or a note specificing which end is which

ok, here's the skinny, I opened my case, and i see that the only thing I have to plug a new hard drive in is this flat cable coming from one of my CD drives, its labed HDDisk. It is female. It isnt nearly long enough to reach the bottom of my case which is where I'm going to put the hard drive. WHAT DO I DO? :)

ROUNDED CABLES - better for airflow, terrible for data integrity. Why? Because in a ribblon cable, you'll see alternating data, ground, data, etc. lines. In a rounded cable, they're typically just bundled all together one on top of another. Even shielded round cable are misleading. They are shielded on the outside (foil), but suffer the same problems on the inside where it matters because of all the lines laying on one another and not seperated. The reason they seem to work ok, however, is because of all the checks done on data integrity at both ends.

However, I'd recommend the Gladiator RD3XP cables by IOSS. I'm using some. They're pretty expensive (generally $20), but are very high quality. Besides the outer foil shielding, every data line inside is set up alternating ground/data, with foil shielding between every layer in the rounded core. I think these cables are a particularly good idea if you're using a TV tuner in your computer (added interference from signals inside your case). In the hardware testing sites, people are seeing between a 9-10% increase in performance on HDTach, Sandra, etc. from the cables themselves.

If you go this route, I'd recommend you stick to the 12" or 20" cables. The 8" is out of IDE spec, as is the 28", by quite a bit. 20" is as well, but not overtly so. (spec is from 10" to 18")

You are preseting correct information about the shielding, but if you buy rounded cables online from a reputable vendor then you will be getting Twisted Pair Rounded cables. These have no problems with data integrity because they take care of the shielding by using TP wires.

Now, if you make your own cables...that is a different story.

I have also heard great things those IOSS cables, wish I had the money for those :(

could anyone link me to an PCI to ATA adapter to plug in a hard drive? How much they cost?

Will this work with a 200gb hard drive? The site says it can handle things bigger than 137gb but how much more can it handle?

If it can handle over 137GB, it supports 48bit addressing. It can handle very large drives. ;) (I'm too lazy to do the math, but multi-TB at least)

They are great. Looks like they're even harder to find now. I got mine from holomaxx, but they have none listed (which doesn't necessarily mean anything...they only list what they have in-stock, which is kind of stupid in my opinion...just put "on order" or something). The only one I've seen in the US looking around right now are 28". Surely there is somewhere though.

Don't forget one thing....these cables do have a ground wire so that the shielding is actually grounded (you fasten it to the drive cage). In at least one test I've seen against the Cobra cables from Antec, they beat them handily (all else staying same, same test).

Link to the test against Cobra cables.

I got the 200GB Seagate from mwave.com This is an OEM, does that mean it doesnt come with the little plastic thing to put on the harddrive on the back so it knows its a slave?
