Default Re: Help with 4000 upgrade

That's good news, would be interesing to see how the new perpindicular drive workout. I need to dig up the head count, cyl, platters and compare to the older models. I now the density went way up with this new technology. I think the 300 is done on 2 platters. I also know that users have had problems with the 300 gig drives. Do not know if was related to their hardware, bios, HW revisions.

Are your 250 gigs the 7200.9 drives?

Pheonix, I'm still going to disagree with you. I still believe it is a hardware hd, cyl, platters that are cause the problem. I think the OS has limits with the values. It may all be BIOS related. I do know that most of the unix flavors now recomend setting the bios to NO DRIVES. This way the OS reads the drive data, not BIOS inturpeted. But since we don't have access to SnapAppliance engineering data, We may Never NO for Sure.

Unless one of their engineers that were layed off due to adaptec purchase finds this forum and en-lightens us. What are those odds????

Edit: Pulled Seagates specs on the 320gig 7200.10 drives
4 heads
2 platters
2.8 amp Startup Current on 12vdc

It use to take 4 platters to get this capacity 2 yrs ago. 3 platters 1 yr ago, How long to 1 platter ???
