I've got a Quantum 40AT IDE drive that I need specs for. # of heads, tracks, sectors, etc. Or perhaps just Quantum's phone #. Thanks.. ---Brian Stretch (stretch@emunix.emich.edu)

Thanks.. With the Quantum Prodrive 40AT use 965 cylinders, 5 r/w heads, and 17 sectors/T. This is the logical format. It physically has 834 cylinders, 3 r/w heads 26 sectors/t. If your system's drive table does not have the logical format drive type, choose a type with the same logical heads and a capacity less than or equal to 40 megs. Note: low level format is not needed. -- ******************************************************************************** Disclaimer: My company knows not what I say (or do).

Am I missing anything? > My mistake, the Quantum 40AT uses RLL 2,7 encoding which without thinking I gave it 26 sectors. As you may know this is not always the case. The 40AT has diff. number of sectors depending on the location of the sectors (more in outer tracks, less in inner). I don't know how many zones are used or the # of sectors in each zone.
