I cant seem to figure out how to post to the answer section so i will
do it in the comments part. IF you want to add files to a CD-R, Dvd-R
or a CD-rw or a DVD-RW thenn you must configure your cd/dvd burning
application to "NOT" finalize the cd. If you have it set to not
finalize the cd than you will be able to add files at a later time by
putting the media, whichever it may be in your cd-r,cd-rw,dvd-r,dvd-rw
drive which ever you have and your sofware will be able to burn
additional data onto it. It is impossible to "write protect" a cdrw
since it is a rewritable medium the files on the disk can be set to
read only under the properties box, but if you set any burning app to
erase the drive it will ignore the files and replace all the data with
0's making it a blank disk once agian. harddrives, and usb thumbdrives
are the same way. they can all be erased and filled with additional
data, for example you can set a file in windows to be a read only
file, that is it can only be opened but not modified, but this is only
within windows itself, if you use a boot disk, or boot from a windows
cd, you can erase the entire drive, basically meaning that no files on
the harddrive where every realy writeprotected, as for a floppy disk
the write protection on those are acually a hardware solution, when
the little switch is in write protection mode its pushes a switch
inside the floppy drive that stops the writing part of the floppy
drive from writing and data or erasing it for that matter. USB thumb
drives are simular to a harddrive because the files can be set to a
read only setting but they can still be formatted and thus all data is
lost. Hardware solutions are the only ways to for surely "write
protect" the data. If you would like to protect your data on your cd's
so that they are not erased i would suggest that you use a cd-r since
they can only be written to one time, plus cd-r's are cheaper and more
compatible with different kinds of hardware. |
