意義如下：
-
第一個軟驅
/dev/fd0. -
第二個軟驅
/dev/fd1. -
第一塊硬盤
/dev/sda. -
第二塊硬盤
/dev/sdb, 以此類推. -
第一個SCSI CD-ROM
/dev/scd0, 可以用/dev/sr0.
sda1, sda2是sda這塊硬盤上的兩個分區。

Device Names in Linux
Linux disks and partition names may be different from other operating systems. You need to know the names that Linux uses when you create and mount partitions. Here's the basic naming scheme:
-
The first floppy drive is named .
/dev/fd0 -
The second floppy drive is named .
/dev/fd1 -
The first hard disk detected is named .
/dev/sda -
The second hard disk detected is named , and so on.
/dev/sdb -
The first SCSI CD-ROM is named , also known as .
/dev/scd0/dev/sr0
The partitions on each SCSI disk are represented by appending a decimal number to the disk name: and represent the first and second partitions of the first SCSI disk drive in your system. sda1sda2
Here is a real-life example. Let's assume you have a system with 2 SCSI disks, one at SCSI address 2 and the other at SCSI address 4. The first disk (at address 2) is then named , and the second . If the drive has 3 partitions on it, these will be named , , and . The same applies to the disk and its partitions. sdasdbsdasda1sda2sda3sdb
Note that if you have two SCSI host bus adapters (i.e., controllers), the order of the drives can get confusing. The best solution in this case is to watch the boot messages, assuming you know the drive models and/or capacities.
