[sleuthkit-users] Imaging a formatted CDRW for direct drives

Here's a problem...

I have some CDRW's that were used/formatted for direct drives on Windows.
The software to read/write was either Adaptec Direct CD Wizard 3.01X
or Roxio. You probably get the picture.

I need to image them to find what data was on them before.

I am resigned to the fact that due to possible corruption (a fact I have
not proven yet) that I might end up looking at the image in a hexeditor.

Here's the problem...

Two discs have now been subsequently formatted as a ISO-9660 CDR data
disk (the discs are all Imation CD-RW discs). One of them only has a
14 MB image now except I know there was more data there on previous formattings.

Attempting to image the disk with dd on linux fails to grab anything
other than the current 14 MB ISO-9660 image.

[1.] Is there a way with dd to image any other data on the disk(s)?

Secondly, some of the discs now appear unformatted although they had
previously been used as CDRW/CDR discs.

[2.] Is there a way to image these discs to extract any data that once
resided on them?

Please tell me my only option is *NOT* an electron microscope.

Thanks list.
