I have a CD that was started in a 'multi-session' format, about 10 years ago, using CD writing software that I no longer have, on hardware that is long gone. The disk has files on it that are otherwise unavailable, but my current setup doesn't understand the particular non-finalized format of the disk. Does anyone here know of any utilities that can read this sort of disk?

the gory details: the disk was written with something called 'adaptec', that came pre-installed on what was probably a windows 95 or possibly windows 98 packard-bell, definitely pre-DVD era. I'm currently at windows XP SP3, but if someone says windows 7 can do it natively, that'll be a good excuse to upgrade.

Do you need an excuse to upgrade from Windows XP to Windows 7? ;-) –  T.J. Crowder Jun 3 '10 at 23:59
    
@T.J. Crowder: no, no I don't. But something like this might put it 'in the budget', if you know what I mean. –  JustJeff Jun 4 '10 at 1:10

IsoBuster, CDRoller, or CD Recovery Toolbox Free might be able to read the data back off of that disc. CD Recovery Toolbox Free is, well, freeware, but not as powerful as the other two. IsoBuster has free functionality and Pro functionality that requires registration. If you burned the disc as an open multi-session disc with Easy CD Creator, then the free functionality should be all you need. If you burned the disc with DirectCD, then you'd need the Pro version.

Both Easy CD Creator and DirectCD were Adaptec products.

Finally, there's Roxio's UDF Reader -- that may also allow you to read the disc. Roxio took over the development of Adaptec's CD/DVD burning software several years ago.

+1 as I would have recommended IsoBuster as the tool to do it. I've been using it for a decade, and have not had the need to try anything else. –  paradroid Dec 17 '10 at 14:40
