Staggered Spin Up Help

irasnyd

I've purchased 4 Maxtor Diamondmax 10 hard disks (6L300S0 model, BANC1G10 firmware) and a Promise SATAII150 TX4 controller for them.

I would really like to enable staggered spin up, which both the drives and the controller claim to support. The documentation linked to in the BIOS detection thread (stickied, above) states that you can use a jumper to force staggered spin up to be on.

If I put a jumper on each of my drives, and boot the computer, they do not spin up at all. If I take off the jumper (then the Pin 11 on the drives is grounded, I've checked with a multimeter) then the drives all start normally, but all at once (which is what I'm trying to avoid with the staggered spin up)

So has anyone managed to get staggered spin up working, and can you give me some pointers?

Thanks,
Ira

try linking the tech docs here that show how it's supposed to be jumpered. Sorry I'm to lazy to go google and dig up links you probably have bookmarked.

Here is the pdf from Maxtor explaining how to enable staggered spin up: http://www.maxtor.com/_files/maxtor/en_us/documentation/white_papers_technical/staggerd-spin-detection-pin11.pdf

Specifically, the first table on the last page of the document is the important part.
