I have been using InCD in my desktop for years because I like the convenience of using InCD and being able to use a backup program to synchronize files on my hard disk with those on a DVD-RW.
So after some deliberation, I finally took a deep breath, uninstalled NTI FileCD, and installed InCD 4.2.4.1 in my Acer Aspire 2003 laptop.
A full format of a DVD-RW went OK in the Matshita DVD-RAM UJ-815A drive. Then while copying more than 2GB of files to the DVD-RW, I got a blue screen and the system restarted.
When the laptop restarted, I optimized it by setting the ATI display OpenGL, DirectCD, etc. all to 'performance' instead of 'quality' and Windows colour quality to 16-bit instead of 32-bit. Also, in Control Panel - System - Advanced - Settings - Advanced, Processor Scheduling was set to background services instead of programs. Then I did a quick format of the DVD-RW in InCD and copying 2GB of files to the DVD-RW in Windows Explorer proceeded smoothly.
So it looks like you have to make the system as efficient as possible to reduce the chance of seeing the blue screen.
However, for really important data, I would not rely solely on a RW disc formatted with InCD or any other packet writing software. And instead of moving files, I copy all the files before deleting them from the hard disk, in case some adverse event arises.
Perhaps some of you might reason that it not worth all the trouble - might as well not use PW. Of course, you could use an RW disc with a mastering software such as NTI CD&DVD Maker,
Nero or
Easy CD Creator to record to RW like recoding to a R disc. This might be the safest way to go. It's more convenient not to wear a crash helmet on a motorbike, but you have to bear the consequences when a crash occurs. If you ride REALLY carefully, though, you can lessen the chances of a crash.
