Look for the 'sg3_utils' package... It can send all sorts of SCSI commands. One may already retrieve the information you are after.
Worst case, there is an 'sg_raw' which will enable you to send a raw SCSI command to the device. Reference the SCSI Block Commands (SBC) from the t10.org. for information regarding the actual SCSI OP codes themselves.

Hello All, I did tried lot of googling but still not much help, I would like to send scsi command (just as we prepare inquiry packet )to find out disk geometry. To my understanding there is a command definied in scsi spec called "Read Formant Capacity" which I suspect should solve my purpose and secondly I couldn't find packet description any where. I was wondering if some one came across the same issue and could provide some pointer or help. Regards, Vipul.
