Jumper

As we all know by heart, there are currently 3 SATA standards. The good ol’ trusty SATA 1 (1.5Gb/s – yay, it’s already slightly faster than IDE!!! In theory!) with the awesome cables that had to be modified for the next revision (because these bitches can fall off like… for no reason), the SATA 2 (3 Gb/s) and finally SATA 3/6G (6 Gb/s) – sorry eSATA, I’m gonna ignore you completely… Right now 3 is only on mainboards and I don’t know of any drives that would come with it, which is cool, because even flash isn’t that fast YET (yes, I know what RAID is). That means realistically, (next to) all current drives in shops anywhere, would be SATA 2. These drives are usually downwards compatible to SATA 1 and this is where the trouble begins. When 2 was brand new, most 2 drives came with a jumper setting, enforcing 1 behavior – many people would probably still connect them to a 1 board after all. For some time now this is no longer the case, even worse: some drives don’t even have outside pins anymore, that can be set to 1 compatibility. Some drives still have pins, but those don’t do anything (that’s documented). I had an ugly experience with a Samsung drive, that could be set to 1, but only via a software – but how are you supposed to do that, if only 2 recognizes the drive in the first place? Yes I know, my hardware is FUCKING OLD, still. This doesn’t help owners of 1 hardware at all. Right then, it’s no different to hardware without that backwards compatibility. So, for the compatibility to make any sense whatsoever, it must be possible to set it via jumpers on the outside manually – the rest is almost destined to be a placebo. It sucks enough with a drive, that can be configured from the outside (think Seagate), because they stopped delivering the jumper itself. It’s incredible where companies try to save money. How expensive can such a little piece of plastic be? 5 cents? I never saw a shop that sold a bag full with these jumpers. I solved the situation, by removing one from an old IDE drive. Thanks a lot!
