copied two files onto a DVD+RW disc. Then tried to insert a new folder but
windowsXP could not do this as the disc was write protected. Tried to
alter the atributes but that was refused. I now have a 4.7gb disc which is
locked. How can I use this disc as a working disc to write and delete as
necessary.Thanks Ron.
What you want to do is use a DVD+RW disc just like you would a hard disc or
a floppy disc, just adding, deleting expanding files etc. The normal DVD
writing utilities can only transfer files in one block at a time. Although
DVD discs are intended to be multisession, DVD drives vary in their ability
to handle such discs, at worst some (particularly older drives) being able
to burn but not read sessions other than the first.
What you require is to use the disc in 'packet incremental' mode using
software designed for the purpose. Examples are provided with both Roxio
and Nero CD/DVD burning products (but there may well be others). In Roxio
the packet incremental utility is known as 'Drag-to-disc' and Nero contains
the comparatively crippled 'InCD'. In each case, you have to format the
disc before you can use it, but in the case of DVD+RW, you can start to
write data while the the disc is still formatting (with DVD-RW you have to
wait the hour or so it takes to format the disc). Once formatted, the disc
is used just like any other disc with a drive letter (DVD+RW can be ejected
before the format has finished but *not* DVD-RW). However, the disc can
only be read in PCs that have the relevant software or at least a reader
driver installed.
As a word of warning, try to only use DVD+RW discs in this mode as DVD-RW
are much more unreliable due to technical differences between the two
formats. If your DVD burner is able to use DVD-RAM discs, these are far
preferable to either of the alternatives because, although slower and more
expensive than DVD+/-RW, they are even more reliable; have a much longer
life and Windows XP supports reading from and writing to them out of the
box - and they work natively just like any other drive lettered disc.
