Hello again,
Whoever said all this was "Easy" was working in the sales department!

In real life it is rarely so!
Microsoft uses a set of upperfilters and lowerfilters in the Windows Registry, and these entries are necessary for Windows to see your drive. Windows frequently has a 'hissy-fit' when you install or uninstall cd/dvd burning software, and breaks the filters. The solution to that is to follow the Microsoft proceedure
HERE, but since deleting your upper and lower filters also deletes the Roxio filters, you have to REINSTALL THE ROXIO SOFTWARE after you do the Microsoft proceedure.
The MS proceedure should get your drives back visible to Windows, and should be done regardless of whether or not you decide to continue trying with this version of Roxio software.
Updates:6.2.130 was the latest version 6 that was put out, so if your disc installs that, then you're as updated as you're ever going to get. If your disc installs a lower version number, there were updaters available which took you up to 6.2. HOWEVER I can't find them available for download anywhere on the Sonic/Roxio sites. Sonic has dropped everything earlier than EMC 8 off their software updates pages to save money. [they were published in September 2003, after all].
Unless you can find updaters available from some archival sites, you're going to be stiff out of luck for updates and might have to put up with an earlier version number. I trolled through a heap of sites on the Internet, but the only download links they had were back to Roxio and were no longer valid.
Note: there were separate updaters available for Basic and Platinum, so if you find some updaters you'll need to get the one which matches the version that you have.
'Nother note: if everything goes swimmingly and you find a cache of updaters somewhere, I would suggest you abandon Drag-to-Disc anyway. It is considered reliable only for temporary storage since its discs are often unreliable and can't always be read on another machine.
RoxioUser12345, I'm sorry if this post seems pessimistic but I'm presuming that you'd rather I said it as I see it instead of encouraging you with false hopes. The software is very old now [in computer years] and resources for it are few. The odds are stacked against you.

I would suggest you do the MS proceedure to get your drives seen again in Windows. Then if a simple install from your CD doesn't do what you want, I'd suggest uninstalling version 6, cleaning the system out with Roxizap, and going after some more recent software. You don't need to buy the latest version if you don't need all the bells and whistles, but you should be able to get a pre-loved version of something between 6 and 11 [a.k.a.Creator 2009] on eBay or Amazon quite cheaply. Just avoid cut-down OEM versions [Dell and the like] since they're not worth any money you might pay for them.
Whichever course you choose, I wish you the best of fortune.
Regards,
Brendon
