Linux Partition Naming Convention ( IDE Drive Mappings ) Posted on May 4, 2006March 6, 2009in Categories Debian / Ubuntu, File system, Linux, RedHat and Friends, Suse, Ubuntu Linux last updated March 6, 2009Q. 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?
