New Quantum Atlas 10K III not U"160" but "40"

[EXman]

During Boot up the HD reads as Quantum Atlas 10K III "40" where the old X15 I had read "160." with the exact same set up.

What to do?

I checked online for configuring the drive and I see nowhere to make it run faster or slower. Just ID's and spin options mostly.

EDIT: please read whole post before answering as it is a dialog and I have gotten the change your cable thing like 3 times! Yes I changed the cable! I have checked the entire bios forward and backwards. Checked the jumpers too. been crawling around their website for days as well! And thanks to the many people who have helped me along the way you are what makes AT worth being a part of!

I think you can change that in your SCSI BIOS....hit ctrl + A upon detection of your adapter during boot-up...somewhere in configuration, can't recall for sure....unless drive is connected wrong...either with wrong cable or on wrong channel.

 

[EXman]

thanks I need to change ID too ... i HOPE THAT WORKS oops cap lock

anyone else have some input?

 

[earthman]

I don't know about the settings, but I assume you have the twisted LVD cable for this?

 

[EXman]

I got a 4 device rounded LVD cable w/termination. Maybe I need to swap it out with my old LVD cable that was hooked up to the X15? but the one I have now is 68pin LVD. Sorry I am a newbie to SCSI only been like 3 weeks

 

[GoSharks]

make sure the drive isnt jumpered to be in SE (single-ended, 40mb/s) mode. also if this is an 80 pin sca drive, make sure the sca-68ping convertor is LVD certified (compatible)

 

[EXman]

ya there are no jumpers on it at all and it is a 68pin drive. by default I hope it be set to 160 like the seagate yet I am getting 40 not 160 new out of the box

 

[bassoprofundo]

What gosharks said is right. You've either got the drive jumpered wrong, or you've got a converter problem. LVD drives have a jumper that can force the drive to operate as an SE (40mb) device for compatibility with older cards. That's probably the problem. What SCSI adapter are you using?

 

[EXman]

I am using a Adaptec 29160 card. and I put in straight out of the box no jumpers as I thought it would default to its intended use at U160. Maybe I am dense But on the maxtor site i do not even see any jumper for switching between 40 and 160? let me find a linky!

 

[Sir Fredrick]

If it's showing up at an Atlas III, are you sure that you have an atlas 10K III? They're completely different drives...

 

[EXman]

99% sure mine is 10K III (it is supposed to be) they do make a 50pin atlas III but this is a 68 pin 10K III

Link to Maxtor unfortuanly I cannot give you a direct link. click on product support then enterprise drives then atlas III... crap Now I see jumper settings but there is no 10K III just the II. crap on a stick!

 

[sharkeeper]

Try another cable or connect it exactly like your X15. Domain validation on the 29160 *will* drop the speed if it detects any inconsistencies with your cable. I had this problem with a X15 (it was actually running at 80) and swapping the cables fixed the problem.

Cheers!

Hey Chris, for ID 0, you shouldn't need any jumpers on there at all. Take EVERYTHING OFF! (off the hdd )

ID 1 would be a jumper on the fourth starting from the right. Then ID2 would be third from the right, ID 4 would be 2nd from the right, and 8 would be the very first on the the right.

You shouldn't need any jumpers on there at all though.

Also make sure the drive is terminated properly. If it's the ONLY drive on your chain, then be sure it's way at the top right before the terminator. If you have it towards the bottom, then a few empty connectors, then the terminator, that might cause some problems.

Hope that helps. LMK if it still doesn't work...

 

[EXman]

No luck man I got everything switched out just like the X15. I took it out and looked at the jumpers took them all off but it only made it ID 0 (well at least that works ) but still running SE ("40") what a Pain!

Update the adaptec bios with the newest version.

 

[Pariah]

Benchmark the drive with HDTach, the STR portion of winbench or ATTO. If these report STR's over 40MB/s you know your drive is operating fine regardless of what the Adaptec BIOS says. There was an issue with Tekram cards incorrectly reporting the SCSI revision for Atlas 10K II's, which was fixed in a BIOS update, so this maybe something of the same sort.

 

[Dunbar]

If this is the only device on that chain than 40MB/sec is plenty of bandwidth. I doubt you'll ever see the drive even peak over 40. But yeah, it's kind of a bummer it's not running at U160.

StorageReview has the 10k III peaking at ~54MB/s

 

[EXman]

GoSharks yu are correct. But I am running out of options thanks for all the help guys but it is stuck at 40.

 

[EXman]

 

[Pariah]

Have you tested the drive yet? Post your HDTach graph.

 

[soulm4tter]

have u tried another scsi cable? try the one you used with the X15. I've never seen a rounded LVD cable.....

 

[EXman]

I am working on flashing the BIOS for the 29160 card but I got to figure out how to make a bootable diskette in winXP first.

Yes I have used a regular flat cable like I used with the X15. no help.

 

[RSMemphis]

Is there another device on the same ribbon as the harddisk, like an SE CD-Rom drive?
Because I think an SE device forces everything on the same cable into SE.

 

[EXman]

Nope it is all alone for the moment I have some on another channel though.
