1. We have raw disks but how to identify raw disks. Is there any command to identify its type and size.
2. How to differentiate between disks which are used as file system and that are still available to be used as raw. I know we can use df -n to find out the file system. but is there any proper indication in disks that differentiate between them.
As root, start the format utility, select a disk and the use the inquiry subcommand:
Code:
# format

And if you mean "raw devices", there is no easy way to find out for sure, if a diskslice is free. It could be used by a volume manager or a database for example.
