Anyone use OKgear sata II cables with a Sata 2 drive?

Many retailers sell these cables and advertise sata II compatible, but i've tested my Seagate sata 2 drive with these cables vs the cable that came with drive, and the OKgear cable won't work with the drive correctly

heres an example

there are no SATA II cables. All cables are compatible with SATA 3G or whatever it's called. Additionally, I do not see an example.

I do not believe all cables are sata 3g compatible.

I purchased 6 of these cables, 3 of which won't properly detect my seagate sata 2 hd. although all the cables work fine in a sata i enviroment. The cables that comes with the hd, and motherboard, both detect the harddrive with no error.

I am almost certain that there is no difference in the cable spec for SATA/150 and SATA/300. If you really want to find out:

$25 buys you the spec.

Just because your 'well-marketed' cables do not work as advertised, doesn't mean that the spec is wrong, just that your cables are crap.

yes, my point is that cables do one thing, bring electrical signals from A -> B. There is no magic involved. One of the reasons to move to serial signalling systems was to reduce crosstalk, i.e. enable higher singalling speeds on fewer pins. If your cable is advertised to support 3G signalling speeds, but it does not, then it either either broken or was junk to begin with.

Since you have three out of six premium cables that do not work, while the stuff that came with your mobo, which is most likely cheap because it's bundled, has no problem, then it leads me to believe that either the cables you have were damaged in packaging, damaged in transport or they are just junk to begin with. Your guess is as good as mine. The bottom line is: If they don't work RMA them.

So your point is that, my sata cables are crap, and that is why they don't work. GREAT explaination.

Any other opinions please.

Isn't this the same as the USB 1.1 vs. USB 2.0 cable debate?

From a "theoretical" standpoint, there isn't (as far as I know) any specification difference between SATA1 and SATA 2 cabling. Now, it may be that people advertising SATA2 cables use higher quality wires, better shielding/sleeving, nicer connectors (or ones that lock), etc., to justify some of the markup, but they should be interchangable. A quick Google search seems to confirm this (see, for example, http://www.overclock.net/faqs/99397-there-difference-between-sata-sata2-cables.html, which includes comments from someone with Seagate's technical support)

One last bit of troubleshooting: since we have backwards-compatability with SATA: for the 3 suspect cables: you mentioned that they work in a SATA1 environment. Is this with the same Seagate drives or with different drives?

In any event, it sounds like you probably just have bad (or at least flaky) cables.

Thanks for your input.

Right now i have a few SATA I Western Digital drives that work fine with the cables.

The Seagate 500gb Sata II won't detect properly at all with these cables, but works 100% fine with the cable that came with the motherboard/hardddrive.

After reading that article, i'm confused these cables work with sata i drives, but cannot operate witht he seagate sata 2 drive.
