[gentoo-server] Checking a block device

[GNUbie]

Hello all,

How can I check if a block device (partition) has one or any of the
following characteristics:

[1] raw

[2] has content

[3] formatted

but without actually mounting it?

Please advice. Thank you in advance.

Regards,

GNUbie

testdisk (http://www.cgsecurity.org/wiki/TestDisk) will tell you that.

This works also as root:

file -s /dev/sda1

Having just cranked out something where I needed similar info [1] I
found that the file command doesn't understand all blockdev/filesystem
types.  The blkid command is a little bit better at that.
