This is an odd question, to be certain, but I need to find out what size a 1.5 TB drive is to help me create a sparse/fake array.
(Personally, I think you're making your job a lot harder than it should be. Just wait til you have the real disks, and do your array creation then with no gimicks.) That being said, while all drives can have slightly different numbers of LBAs, vendors seems to be standardizing on the IDEMA formula in their "Document LBA1-02: LBA Count for IDE Hard Disk Drives Standard" LBA count = (97696368) + (1953504 * (Desired Capacity in Gbytes - 50.0)) Just plug in 1500 for "desired capacity in Gbytes" and it should tell you what most vendors are configuring their 1.5TB drives to. I just checked, and the 1.5TB Caviar Green spec sheet on wdc.com indicates exactly the resulting number of LBAs when you plug in 1500 to the above formula. --eric -- Eric D.
