For a prerecorded CD or a CD-R, "Format" makes no sense. That would
apply only to a rewriteable disk (CD-RW). I'm not sure about the
others, I assume that "Make compatible" also applies only to CD-RW.
A Google search says that DLA is "Drive Letter Access" a Roxio thing
that "turns your CDs and DVDs into virtual hard drives". That also
would need a CD-RW.
Wrong.
You can format a CDR using DLA and then just drag and drop file to the CD
via windows explorer.
The problem is any other machine you want to use the disc on has to be
capable of reading the disk created in such a way.
You need to choose the "make compatible" option to use the disc in a
"normal" pc. The problem there is that once the disc has been made
compatible, no more files can be added to the disk using the DLA method,
(unless it is a RW disc, then it is automatically made compatible before you
eject the disk, then and made "incompatible" when you insert the disk
again.)
Since the OP has "lost" these features, he has either made some change to
his system and uninstalled DLA, or maybe his writer is on the fritz and not
being recognised anymore, or it is even possible DLA is incompatible with an
XP update.
Sonic made a version of this some time ago, but with the rise of USB storage
this type of software is not so useful anymore.
Try reinstalling the writing software that included the DLA software.
Suffice to say, it is not a native XP function.
