How to remove the jumper on seagate 500gig?

I heard that there is a jumper on the 500 gig seagate that allows full 3gb/s ,how do i unlock/remove it?

it seem that its the block at the back of hard drive -- if remove then it will run at 3Gb

Unless it's easy to get to don't bother with it, you won't notice a difference.

All that removing the jumper does is allow the drive to run in SATA2/300Mb/s mode, it's not actually capable of sustaining more than about 80Mb/s so all that improves is the burst rate from the cache. The real world effect of this is just about negligible.

so there is no point of removing it?

I see where's the jumper but i dont know how i must remove it - do i have to pull that piece of thing that is on 2 pins?

i have 4 pins there - 2 of them are blocked becouse of it,do i need to just ,, you know ... pull it?

Yeah, just pull and remove the small grey plastic thing, it's just a small piece of coated metal which forms an electrical connection between two pins.

thank you very much!

are you remove the block from the pin? it for the factory use only but it up to you if you want to remove... I just leave it in my 2x500GB Seagate... it seem run lots fast...

I think forgetting to remove one from my 4x 500gb RAID5 array is causing my hd-tach benchmarks to fluctuate horrendously :s
whether they actually make any difference or not is debatable; but make sure they're all the same; I've got to power the box down again

While your at it turn the NCQ off too, it messes up RAID performance something chronic. I got about 20% better performance on my RAID5 array when I disabled it on all the drives.

yeah, ncq is a nightmare sometimes, on nvidia arrays it makes them crawl!
