Hi bakunin,
I had gone through google prior to posting and couldnot identify whether my filesytem is made of the rawdisks or non-raw disks....
I could understand that 'c' indicated character and 'b' indicated block access. But still i couldnot decide on whether my machine uses raw devices or not...
Regards,
Jibu
