Linux: Mount: Error: device is not a valid block device

---

A block device is a device that sends blocks of data with each read
or write.

---

Examples of block devices are:

 - CD-ROM

 - Direct Memory Access (DMA)

 - floppy drive

 - hard drive

   - IDE

   - SCSI

---

Thus this error means that you try to connect to a non-block device
(thus you try to connect to something that is not a disk, or
not a floppy drive, CD-ROM or not a USB solid state flash disk, ...)

In Linux Red Hat v7.3 only:

Steps: Overview:

 1. -vi /etc/fstab

 2.  -add 'udf' in the line saying:

       /dev/cdrom /mnt/cdrom iso9660 noauto, owner, kudzu, ro 0 0

      so becoming after this:

       /dev/cdrom /mnt/cdrom udf,iso9660 noauto, owner, kudzu, ro 0 0
