Help: need to find out the information about the harddisk data distribution status

[Jackie Tai]

Hi All



I'm a master student and I'm currently working on a project, in order to
complete the report, I need to find out the information about the harddisk
data distribution status, such as the number of files on each cylinder
group, the occupied status on each cylinder, the files layout on each
cylinder block etc…..

I wonder is there any command or way that can show the low level information
about the harddisk that similar to what I describe above, I have been
searching on the Internet for a week but I only found something like: di
diskusage diskinfo …. Etc they only report the data usage or free space
which not I want, I also found a command call "fstyp" it look that it can
report the harddisk number of cylinder blocks availability, although I can't
found that command on FreeBSD.



Any help or guidance will be greatest appreciate.



Thanks

Jackie
