I came to search this site specifically to resolve a problem I had backing up Quicken. I previously had InCD which despite dire warnings always worked reasonably OK for me in both Win2K and XP but only when used with the drive software came bundled with. I have since bought a LiteOn LDW-411S (bundled with Sonic, not Nero)and found all worked perfectly except Quicken B-U, most irritating. Got directed to Microsoft knowledgebase article (link below) which deals with this exact problem. I am reasonably sure the LDW-411S is Mt. Rainier compliant; problem is Quicken only works with packet writing. In XP the trick is to set the Quicken backup directory to CD Burning Staging area (C:\Documents and Settings\user_name\Local Settings\Application Data\Microsoft\CD Burning) instead of your RW drive, then burning to disc requires a couple of extra clicks and your done. Full details of this fix (method 3 of 3 listed) and 2 other options at link below.
In a nutshell, you can backup Quicken without packet writing software. Bear in mind that once you follow this procedure the file location is saved by Quicken and subsequent backups will be very straightforward.
Later versions of Quicken shouldnâ€™t suffer from this glitch. Must go, my armor needs a polishâ€¦
A late response, granted, but useful, you'll find
