Aug 13, 2011 · the first (1) partition on your first (a) SATA drive is /dev/sda1. The third (3) partition on your second (b) SATA drive is /dev/sdb3. the second partition (2) of the second (b) IDE hard disk is '/dev/hdb2'. This device naming is more of a background one, as the actual point to access it a directory mount point.
See “Naming convention” in the Grub manual if you want more details. /dev/sda, /dev/sdb, etc, are the default names of hard disks (and other similar storage like flash disks of all kinds, but not CD or tape drives) under Linux. The last letter grows in the order in which the disks are detected. You may find /dev/hda, /dev/hdb, etc, on some ...
Drive letter assignment. Alphabetical assignment to logical drives on computers (e.g., C:\) MS-DOS command prompt with drive letter C as part of the current working directory. File Manager displaying the contents of drive C. In computer data storage, drive letter assignment is the process of assigning alphabetical identifiers to volumes.

Understanding the device naming and its usage are essential if you want to competently install and use Ubuntu Linux. Device naming has changed and evolved over the numerous versions of Linux that are constantly being put out as the technology changes. Unfortunately this is not comparable to how Window's or Apple's name and use devices on their prod...
Linux started off by giving each device a name, then a position and then a partition. Under Linux, the original naming convention was: 1. dev/fd0:First floppy disk drive 2. dev/fd1:Second floppy disk drive 3. dev/sda: First Small Computer System Interface (SCSI) disk 3.1. (SCSI ID address-wise) 4. dev/sdb: Second SCSI disk address-wiseand so on 5. ...
GRUB changed the convention by adding a partition starting at zero. The base name for a (E)IDE-controlled disk is dev/hd? The ? is a single letter. For GRUB this equals hd? The ?is position one through four. Naming the devices is straightforward. Taking the first example below, then the first part is the device name hd and then the second part is t...
GRUB2 changed the convention by taking the zero out of the naming convention, this means everything starts at one. The base name for a (E)IDE-controlled disk is dev/hd? The ? is a single letter. For GRUB2 this equals hd? The ?is position one through four. Naming the devices is straight forward. Taking the first example below then the first part is ...
Serial Advanced Technology Attachment (SATA) Drives:
1. With the advent of SATA drives, the convention changed and now hard drives are mostly referenced as sda instead of hda. Where sd stands for serial drive.
Partition Tables:
1. A partition table shows the partitions of a hard drive or any other storage device. There are two standards for the layout of the partition table:
- / -- The Root Directory. Everything on your Linux system is located under the / directory, known as the root directory. You can think of the / directory as being similar to the C:\ directory on Windows -- but this isn't strictly true, as Linux doesn't have drive letters.
- /bin -- Essential User Binaries. The /bin directory contains the essential user binaries (programs) that must be present when the system is mounted in single-user mode.
- /boot -- Static Boot Files. The /boot directory contains the files needed to boot the system -- for example, the GRUB boot loader's files and your Linux kernels are stored here.
- /cdrom -- Historical Mount Point for CD-ROMs. The /cdrom directory isn't part of the FHS standard, but you'll still find it on Ubuntu and other operating systems.

Mar 26, 2012 · ‘Drive C:’ is essentially a CP/M term (CP/M was an 8-bit operating system that DOS heavily, ahem, borrowed from). In the days of floppies, ‘drive’ and ‘filesystem’ were equivalent: either your drive held a floppy disk with exactly one filesystem, or it was unformatted (or empty). Easy to make the link and think the two are synonyms.
