Unhappy How to read the whole tracks from harddisk?

Dear all,

I would like to ask whether I can read the whole tracks from the harddisk (I am using a SCSI harddisk) in kernel mode. Should I send any SCSI command directly, or is there any kernel function that I can call? Thank you very much!

Disks access, or any block device access are usually done through the buffer cache.

Thanks for your answer.
But, maybe my question is not so clear, that seems not my expect answer. Let me put it in this way, I know I can get the data from the harddisk in terms of block, but can I give a command or a call to get the data track by track from the harddisk?
