I saw your latest post when I tried to upload my answer to your previous three posts. I'll only add a comment at the end, leaving the rest as it was before your post.
Let's start with the first of your three latest posts.
You should have renamed Cdr4_2k.sys and Cdralw2k.sys in C:\WinNT\System32\Drivers before running RegClean (see S11.3; we'll come back to this point later).
As for your Nero InfoTool report, you have DMA off for both the burner and the CD-ROM drive on the secondary channel; I'm not sure if your burner can work with DMA on, but you could try this later (it might not matter for the burner, but you could get higher reading speeds for the CD-ROM drive).
Concerning Driver Information, you still have Cdr4_2k and Cdralw2k (which will have to be removed), but the rest looks OK; in particular, the VERITAS drivers dmio and dmload are legitimate under W2K. Well, I'm not quite sure about Dantz Retrospect's roff, but it may be harmless. BTW, incdrm comes from EasyWriteReader, which you forgot to mention earlier!
As for ASPI Information, apparently your System ASPI is Adaptec's ASPI 4.60, but I don't know why only Wnaspi32.dll is listed, so could you check whether Nero InfoTool | ASPI | System shows only this file and says "System ASPI is installed and working correctly"?
You may now prune down the Nero InfoTool report by deleting from the beginning till Driver Information, then all the Microsoft drivers and .dll entries.
As for why you couldn't edit your previous posts, maybe you were not logged in? When I'm logged in, my previous posts have five icons: Show Profile, Email Poster, Edit Reply, Reply with Quote, Delete Reply.
Concerning your latest post, I gather you upgraded to Nero 22.214.171.124a, and just reinstalled InCD 3.52.20b. Did you also reinstall EasyWriteReader? The version you had been running before looked OK, so I'm simply asking for clarification.
I presume you were able to format fresh or fully-erased discs; please don't skip such information!
Do you mean that you don't see the Eject option in Explorer, or that nothing happens when you select it? Similarly for the InCD icon; did you try to use it? Recall that ejecting via the burner's button can be dangerous; see the WARNING in S8 again!
The Nero message you saw is perfectly normal: you should eject the disc first, call Nero so that it takes over your burner from InCD (which normally controls it), and then insert the disc. In general, Nero can record to blank (or erased) discs only, and Nero can be used to erase discs. In other words, if you want to use a previously formatted disc for recording in Nero, you must erase it first.
Further troubleshooting will need the following steps.
In C:\WinNT\System32\Drivers, rename Cdr4_2k.sys to Cdr4_2k.sy_ and Cdralw2k.sys to Cdralw2k.sy_. Before rebooting, call Regedit (or Regedt32 if you prefer) and search for "lowerfilters" (without the quotes). Click on the key in the left pane, and back it up for safety. Then in the right pane delete the entries for Cdr4_2k and Cdralw2k in LowerFilters and/or UpperFilters, if any. Finally, close Regedit and reboot.
Next, check how InCD operates after these changes. For instance, try to format a blank or erased disc, and tell us if everything proceeds as in S8; if you see any discrepancies, report them in detail. Then copy some files to the disc, and try to eject it via the InCD icon; if this works, insert the disc again, note if the InCD mounted message pops out, then try to eject it via Explorer.
If you still have problems, again we will need more information, especially after all the recent changes. So please post the full results of the four dir commands described in S11.1, and the Driver Information section from Nero InfoTool (without the Microsoft drivers and .dll files to save space).
This refers to your latest message.
Thanks for the full dir outputs; just as I thought, Cdr4_2k and Cdralw2k are still present.
Concerning your registry, you should have searched for cdr4_2k, not for cdr4_2k.sys, and similarly for cdralw2k.
As indicated above, the two Roxio culprits should be renamed and purged from LowerFilters and UpperFilters. Afterwards, you may delete them from the registry either manually or via RegClean.
