The "new" output of "scsiformat sd0" is: iomega jaz 1GB J.86 Mode data length: 0 Medium type: 128 Device Specific Parameter: 2 Block descriptor length: 2 Density code: 131 Number of blocks: 24 Reserved: 105 Block length: 7302501 PS: 0 Reserved: 1 Page code: 39 Page length: 97 Number of Cylinders: 2105450 Number of Heads: 97 Starting Cylinder-Write Precompensation: 8003633 Starting Cylinder-Reduced Write Current: 4669984 Drive Step Rate: 8224 Landing Zone Cylinder: 2105376 Reserved: 8 RPL: 0 Rotational Offset: 32 Reserved: 32 Medium Rotation Rate: 18990 Reserved: 56 Reserved: 54 I know the cylinders/heads/sectors info but have no clue as to what the proper parameters are for the other fields, and, as I only have one disk (I use it to back up my hard drive) I cannot extract this information from another. Does anyone have this information? I tried iomega's website but they did not have this info online. Next question: Once I have this information, how do I tell scsiformat to use the new info for formatting the disk. I have edited mode pages (write verify, etc.) but am uncertain as to how you might change the drive parameters. Any help would be appreciated.
