Linux: Mount: Check: How to determine which are valid block devices?

---

Check e.g. the file

 /var/log/dmesg

---

Steps: Overview:

 1. -Open a console, and type the command:

      cat /var/log/dmesg

     or to edit it, using your text processor 'vi':

      vi /var/log/dmesg

       (to quit from vi, type <ESCAPE>, followed by 'q')
        and check for the line of your CD-ROM.

---

For example, on my computer with Linux Red Hat v9.0 it shows the lines
(amongst others)

 hdc: VMWare Virtual IDE CDROM Drive, ATAPI CD/DVD-ROM drive

 fd0: Floppy drive(s)

 sda1, sda2, sda3, sda4, sda5, sda6, sda7: Partition

---

For CD-ROM, check

 /etc/fstab

to see what

 /dev

name is used for cdrom

(/dev/cdrom1 instead of /dev/cdrom, etc.).

---
---

There is also the shell command:-

if [ -b /dev/hda ] ; echo "block"; fi
