<p>This page is intended to help new Linux users and Windows users identify their hard disks / CD ROMs in a Linux box.<br><br> |
| 120 |
|
|
<!--empty-line--> |
| 121 |
|
|
Linux disks and partition names may be different from other operating systems. You need to know the names that Linux uses when you format, mount or select partitions or disks.<br><br> |
| 122 |
|
|
<!--empty-line--> |
| 123 |
|
|
Linux uses the so called <b>device name</b> to access disks and partitions. You can think of it as a link to the actual driver of the disk. All available devices have a corresponding file in <b>/dev</b> (e.g. /dev/hda1).<br><br> |
| 124 |
|
|
<!--empty-line--> |
| 125 |
|
|
In general, each disk / CD-ROM has a three letter name, for example <b>hda</b>. Each partition in such a disk has a number associated with it, starting from 1. So the first partition of disk <b>hda</b> would be <b>hda<font color="Red">1</font></b>, the second <b>hda<font color="Red">2</font></b> and so on.<br><br> |
| 126 |
|
|
<!--empty-line--> |
| 127 |
|
|
Depending on the device type, Linux gives the following names to devices:</p> |
| 128 |
|
|
|
| 129 |
|
|
<ul> |
| 130 |
|
|
<li><b>IDE (ATA) floppies</b><br> |
| 131 |
|
|
The first floppy drive is named <b>/dev/fd0</b>.<br> |
| 132 |
|
|
The second floppy drive is named <b>/dev/fd1</b>.</li> |
| 133 |
|
|
<!--empty-line--> |
| 134 |
|
|
<li><b>IDE (ATA) disks /CD-ROMs</b><br> |
| 135 |
|
|
The master disk on IDE primary controller is named <b>/dev/hda</b>.<br> |
| 136 |
|
|
The slave disk on IDE primary controller is named <b>/dev/hdb</b>.<br> |
| 137 |
|
|
The master and slave disks of the secondary controller can be called <b>/dev/hdc</b> and <b>/dev/hdd</b>, respectively.<br><br> |
| 138 |
|
|
<!--empty-line--> |
| 139 |
|
|
Linux represents the primary partitions as the drive name, plus the numbers 1 through 4. For example, the first primary partition on the first IDE drive is <b>/dev/hda1</b>. The logical partitions are numbered starting at 5, so the first logical partition on that same drive is <b>/dev/hda5</b>. Remember that the extended partition, that is, the primary partition holding the logical partitions, is not usable by itself. This applies to SCSI disks as well as IDE disks.</li> |
| 140 |
|
|
<!--empty-line--> |
| 141 |
|
|
<li><b>SCSI disks</b><br> |
| 142 |
|
|
The first SCSI disk (SCSI ID address-wise) is named <b>/dev/sda</b>.<br> |
| 143 |
|
|
The second SCSI disk (address-wise) is named <b>/dev/sdb</b>, and so on.</li> |
| 144 |
|
|
<!--empty-line--> |
| 145 |
|
|
<li><b>SCSI CD-ROMs</b><br> |
| 146 |
|
|
The first SCSI CD-ROM is named <b>/dev/scd0</b>, also known as <b>/dev/sr0</b>.<br> |
| 147 |
|
|
The second SCSI CD-ROM is named <b>/dev/scd1</b>, also known as <b>/dev/sr1</b>, and so on.</li> |
| 148 |
|
|
<!--empty-line--> |
| 149 |
|
|
<li><b>USB disks</b><br> |
| 150 |
|
|
They are named just like SCSI disks. The only difference is that the partition number has to do with the file system on the disk. If it's <b>/dev/sdx<font color="Red">4</font></b>, then it's a VFAT file system and if it's <b>/dev/sdx<font color="Red">1</font></b> it's probably a linux (ext2, ext3) file system.</li> |
| 151 |
|
|
</ul> |

<p>In order to identify the disks of a system you have to work with, a basic knowledge of its configuration (how many disks it has, whether it's a dual-boot system etc.) is welcomed but not required. A more experienced user will not have to worry about it, though.<br><br> |
| 158 |
|
|
<!--empty-line--> |
| 159 |
|
|
Linux systems based on a 2.6.x kernel (like <b>Clonezilla Live</b> and <b>SystemRescueCD</b>) provide all the necessary support to identify a system's disk configuration, with just a couple of commands.</p> |

<p>The first system I have to work with is a dual-boot system (Windows - Linux), with two disks and two DVD-ROMs.<br><br> |
| 167 |
|
|
<!--empty-line--> |
| 168 |
|
|
The first command will tell me what disks and partitions exist in the system. So here it is:</p> |

|
<p>The output of this command tells me that the system has two disks (<b><font color="Red">hda</font></b> and <b><font color="Red">hdb</font></b>) which are the primary master and slave devices.<br><br> |
| 186 |
|
|
<!--empty-line--> |
| 187 |
|
|
The first disk contains four primary partitions (hda1-hda4) and the second one four primary partitions (hdb1-hdb4) and a logical one (hdb5). Wait a minute!!! this can't be right... In order to have a logical partition, I must have a primary that contains it, which means that in this case I can't have four primary partitions. So what is really happening here is that I have two primary and two logical, plus an extended primary which contains them.<br><br> |
| 188 |
|
|
<!--empty-line--> |
| 189 |
|
|
What remains to be found is what type of partitions they are. I will find that out by executing the following commands:<p> |

<p>Ok, this clears things up. The first disk contains three Windows XP partitions (NTFS) and a Linux Swap partition. In fact, <b>/dev/hda1</b> is the system "disk" for Windows, since Windows will always be installed in the first partition of the primary master disk.<br><br> |
| 218 |
|
|

| 219 |
|
|
The second disk, on the other hand, contains a Linux partition (<b>/dev/hdb1</b>), a Linux Swap partition <b>/dev/hdb2</b>, and an extended partition <b>/dev/hdb3</b> which contains two more Linux partitions (<b>/dev/hdb4</b> and <b>/dev/hdb5</b>).<br><br> |

The final thing we need to know about this system is what CD/DVD-ROMs it has. So I execute the command:</p> |

<p>Although it's the same stick I used with the previous system, which was recognized as <b><font color="Red">sda</font></b> there, now its name is <b><font color="Red">sdb</font></b>. So, its name depends on the system it is connected to, and will not always be the same.</p> |

<p>According to what's discussed up to now, the system seems to have two SCSI disks, but I know it actually has two ATA (PATA) disks. What's going on?.<br><br> |
| 371 |
|
|
<!--empty-line--> |
| 372 |

What is really happening here is that you have one of the newest Linux kernels (using the libata disk driver), which shows <b>ALL</b> disks as SCSI. That does not mean that the system thinks it has SCSI disks, it just names them as such.<br><br> |
