I'm confused about your needs. If you only need to transfer several large files to work each day, you may simply use Nero to burn an ISO compilation to a disc; if the file names don't change drastically each day, you may save the compilation info to your hard disc, then recall it next day and update the file names as needed before using it for burning the next disc. If you get a spindle of fairly cheap CD-R disc (24x or 32x say), the cost of one disc per day should be acceptable, and you won't face reading difficulties anywhere. But if you care about waste, a CD-RW disc could be used; maybe quick erase in Nero wouldn't take too much time each day.
Why do you write about "2 x CDR's every day (one each way)". Does it mean burning one disc at home, and another at work?
Now, back to your InCD problems. Your main Win95b box should be fast enough for InCD, provided you don't run heavy applications while copying to InCD discs. As for previous points:
1. LG is not famous for firmware updates. To find out about practical rewriting speeds of your burner on various media, consult the sources mentioned previously in (1); just search those forums or simply use Google.
2. Upgrading Nero won't hurt you; the main point here is that it will also install the latest versions of CD Speed and InfoTool (these utilities are useful for troubleshooting).
3. If Nero gives an error on Full Erase, decribe it accurately. Also check NeroHistory.log in C:\Program Files\ahead\Nero.
4. Your "me-too" impression is too harsh: Relative to other companies, Ahead typically wins on features and stability, but looses on documentation and tech support.
5. I don't see why being able to read CD-MRW at work wouldn't suit you. For your needs there is little difference between CD-MRW and classical CD-RW packet writing (where formatting 10x media takes about 10 minutes).
6. This is outside the subject, but I use FileSync for primary backup to other networked boxes.
A. For your old boxes, check the LG system requirements for your burner. It's not just CPU/RAM; HDD transfer rates could be the bottleneck.
B. See (2) above re Nero update. Nero can write to blank CD-RWs; InCD must format them first. (If you're old enough, you'll remember having to format floppies before preformattied floppies became available.)
C. See (3) above, and the thread
http://www.cdrinfo.com/forum/topic.asp?TOPIC_ID=7665 Apparently some other programs can erase CD-RWs, but stay away from anything that requires special ASPI, at least for now.
D. I'm using InCD (CD-RW and CD-MRW) discs on various boxes just like floppies, also reading them in DVD-ROM drives.
E. The error codes could assist Ahead in debugging; well, why don't you try to contact their tech support? Even a canned answer would be better than nothing. As far as I know, InCD has no log files.
I understand your desperation, but one of the solutions outlined above should eventually work for you. Otherwise, get a DSL or cable connection at home, and convince your network administrator at work to allow FTP uploads, VPN, whatever...
