13) BLANKING A CD-RW
The whole point of using a CD-RW is that it is REwritable. In other words, you can erase it and burn something else onto it. It only just occurred to me that I should make an addition to this howto, explaining briefly how to do this!
It's very simple in fact. The blank=.... option is what you need to use:# cdrecord dev=2,0,0 speed=4 -v blank=fast
There are several keywords you can use after "blank=", not all of which are useable on all drives. The man page for cdrecord has this to say:blank=type Blank a CD-RW and exit or blank a CD-RW before writing. The blanking type may be one of: help Display a list of possible blanking types. all Blank the entire disk. This may take a long time. fast Minimally blank the disk. This results in erasing the PMA, the TOC and the pregap. track Blank a track. unreserve Unreserve a reserved track. trtail Blank the tail of a track. unclose Unclose last session. session Blank the last session. Not all drives support all blanking types. It may be necessary to use blank=all if a drive reports a specified command as being invalid. If used together with the -force flag, this option may be used to blank CD-RW disks that otherwise cannot be blanked. Note that you may need to specify blank=all because some drives will not continue with certain types of bad CD-RW disks. Note also that cdecord does it's best if the -force flag is used but it finally depends on the drive's firmware whether the blanking operation will succeed or not.
