#try_to_mount_this_device(i) ⇒ Object

#

try_to_mount_this_device

This method will attempt to mount the given input-device. The method can also try to “clean up” given input.

For example, consider the following input:

"Disk /dev/sdb: 977.5 MiB, 1024966656 bytes, 2001888 sectors"

Here, we are only interested in the part between ‘Disk’ and the first ‘.’.

We can also have other flawed input such as:

/dev/sdb1        2048 2001887 1999840 976.5M  7 HPFS/NTFS/exFAT

In this case we will also use a regex.
