What does all this mean??

This is a scan disk from a cdr which was a failed audio disk
re-used as a directed data disk. I have had some problems with it
but I seem to have recovered the disk (although scandick said
it failed to recover the disk!!) 348082+360= 348442 sectors
seem to have been used on the two audio tracks how much is that
in bytes?
Windows reports the disk as 703mb with 337mb free I am wondering if
the software 'knows' about the audio data previously burn't or not?

Maybe I get problems when it tries to write to an area already
written to by the failed audio?

How/where is the directory info written? and how is it added to?
is ther a reserveed area.

Are disks written from the outside in or inside out?
And is it the same for audio and data? (etc....).

Actually I just had a look at the disk using ISOBuster (thanks SMH)
and it shows track 2 is a huge 333mb and track one just one megabyte.
Windows lists the CD as703 mb with 337mb free, the data files
written to the disk show as 287mb.
Also the data is shown as a file as part of track 2, I am
guessing "track 2" is the data files.

Can anyone make any sense of that? I think a data file or two
of about 30mb were 'lost' after being written.

I will continue to write to the disk to see how much data I
can get on it, I expect I will get 650mb+ on it.

Track 1 is the failed audio burn. Track 2 corresponds to the formatted
part.

written to the disk show as 287mb.

You lost some space to the failed audio, and session and formatting
overheads when you formatted cd.

I will continue to write to the disk to see how much data I
can get on it, I expect I will get 650mb+ on it.

Is this the same cd that froze your system?

Yes, I suspected as much as most of my audio failures are very early,
the early failure means it can create more coasters in a given time,
which is a bonus if you are a CDR manufacturer.


Windows lists the CD as703 mb with 337mb free, the data files
written to the disk show as 287mb.

Yes seems resonable.

No its a different one!! I have loads of failed CDs but 'freezers'
are quite a rare beast. (I also now find that none of my old CDRW
disks work at all, thats 10 failed disks!! the whole pack!!) GRRR!!!
This one has appeared unreadable a few times but I have always
(so far) managed to recover it with a 'scan disk'
Unfortunately I have to keep a copy of the data on my hard drive
'just in case', I am not sure whether I should just bin it and burn a
new cd to save me doing the samething laterwhen it does fail
and I will have deleted my harddrive backup by then :O(

Or maybe I will fill the disk and finalise it but then I might
not be able to recover it if it fails again (especially if I make it
so it cannot be written too again)
