Formatting a disc

After determining that the DVD-RAM drive is configured properly, the next step is to verify that the DVD writer can write to a disc. Formatting a disc is an easy test. To do that, we use the command mke2fs -c -v -b 2048 -m 0 /dev/scd1, where:

  • mke2fs—creates a Linux second extended filesystem

  • -c—checks for bad blocks

  • -v—provides verbose output

  • -b 2048—uses blocksize 2,048

  • -m 0—reserves zero blocks for superuser

  • /dev/scd1—the device to be formatted

After we issue that command, the DVD-RAM access light begins blinking, and the text shown in Example 12-8 appears.

Block size=2048 (log=1)
Fragment size=2048 (log=1)
304800 inodes, 1218960 blocks
0 blocks (0.00%) reserved for the super user

Running command: badblocks -b 2048 -s /dev/scd1 1218960
Checking for bad blocks (read-only test): done
Writing inode tables: done
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 35 mounts or
180 days, whichever comes first.  Use tune2fs -c or -i to override.

After the format completes and you mount the device, you can ...
