Linux Partition Naming Convention ( IDE Drive Mappings ) last updated March 6, 2009 in Categories Debian / Ubuntu, File system, Linux, RedHat and Friends, Suse, Ubuntu LinuxQ. I am new to Linux and I not able to understand /dev/hdc (is it C: drive?) under Linux. This is quite confusing for a new Linux user like me. What device naming convention followed by Linux? Can you explain it in layman’s term?
