Nero UDF & UDF/ISO confusion
I have tried various techniques of making an incremental backup CD-R
with Nero 5.5.10.54 using UDF and UDF/ISO formats. I mainly want to backup digital camera photos as months go by, filling up one CD-R at a time. I have "Multisession" checked and everything seems to copy fine (different files on different days, with the original Nero compilation saved each time to retain the layout), but many of the files end up corrupted on the CD-R even though the sizes and names are accurate. They become unreadable, even with an app like ISOBuster. When I open a UDF CD-R in ISOBuster I see many different sessions, some with corrupt files, some without. Usually the corrupted files begin after a certain date, whereas previous sessions seemed to save with no errors. I really don't understand the format. Is Nero UDF or UDF/ISO actually _designed_ to be used for incremental backup like Nero InCD or Roxio Direct-CD? Years ago, Direct-CD never gave me problems but I've gone the Nero route for various reasons. Several CD-RWs formatted with Nero InCD have crashed on me (could be InCD, could be the brand), which is why I've been trying to use UDF or UDF/ISO as a substitute. Is there a good FAQ for this somewhere instead of the scattered forum questions I've found? Nero's program help is very limited. K2 |

Use ISO format multisession with Nero to ensure that your files are
preserved. This is the most robust of the data formats. InCD is flaky and generally considered less reliable than Direct CD. Unless they have changed it recently, InCD will not work with CDR discs. I would not recommend the use of CDRW discs for archival purposes - or, come to that, for any purpose that is not involved with testing. -- Graham Mayor K2 wrote: I have tried various techniques of making an incremental backup CD-R with Nero 5.5.10.54 using UDF and UDF/ISO formats.

I assumed for some reason that UDF was superior for multisession work, but I can see that the same options are in the "plain" ISO format. I'll take your advice there. InCD is flaky and generally considered less reliable than Direct CD. Unless they have changed it recently, InCD will not work with CDR discs. InCD is still for CD-RWs only. It worked fine up until 450-500 MB for several rotating Memorex CD-RWs I was using. Then, they suddenly became unreadable. I had trusted InCD until that point, but I don't know if it was just a brand problem. I recently bought some TDK CD-RWs but the initial InCD formatting process stalled on a test disc after 45 minutes. Not sure what the cause is. I would not recommend the use of CDRW discs for archival purposes - or, come to that, for any purpose that is not involved with testing. I've always followed that rule, too. K2 |

Graham Mayor, were you also born with "Scam Artist" emblazoned on your face? -------------------------------------- Graham Mayor (MS MVP) spewed: I would not recommend the use of CDRW discs for archival purposes - or, come to that, for any purpose that is not involved with testing. According to Mikey, cd-rw is good enough for BACKUP, of all things, even when combined with the supposedly *inherently* flaky, fragile, faulty, unreliable packet writing format! ======================= From: Mike Richter (Acraptec Shill) Date: 9/1/99 You may back up ... to a DCD-formatted erasable. ======================= Don't you believe Mikey's words, Mayor (MS MVP)? BTW, is the distinction between Specification, Standard, Format and Implemention beyond comprehension of MS MVPs? |

You keep comparing InCD to UDF, but InCD IS a UDF file system. You can't compare the two as they are the same thing. Only a true backup program can provide true backups. I don't think you want to do incremental backups, which backup everything on your partition that has had the archive bit set since the last full backup. You just want to write a few files to the CDRW at a time. That's fine, but don't call that an incremental backup. I'm sorry, but any packet-writing program, be it Roxio or Nero, is flaky. They work fine until they don't, then you are screwed. Use them long enough and you WILL lose data, as you have eperienced. Just juse regular, multi-session mastering, on a CDR. CDRWs seem to have more failures. I have no scientific data to validate that, but reading here, elsewhere, and talking to others in the profession seem to indicate that. |

I see that, and I don't understand why Nero shows the standard multisession options in UDF or UDF/ISO mode. It sure makes it look like multisessions should work with UDF. Many InCD troubles are caused by conflicts with Roxio junks, like winxp built-in burn function, WMP burn-plugin, left-over DirectCD files, etc. My problems with InCD are hard to figure, as it worked mostly flawlessly until the discs reached a certain capacity. I cleaned out all the Roxio leftovers I could. Check out (S11) of 'KCK' InCD trouble guide: http://www.cdrlabs.com/phpBB/viewtopic.php?t=9572 (XP) Quoting from that link: "In particular, Memorex CD-RW discs are not recommended." I had problems with that exact brand, so I'm more suspicious that it's a disc quality issue. K2 |

For a few weeks I thought the same thing; multisessions seemed to work fine. Then I noticed recent files were getting corrupted, even though the burning seemed to go fine and they appeared intact from their size and names. I'd give it more time if I were you. Be sure you actually try to launch the files you've copied. K2 |

Compounding the problem is writing to faster media than the burner. For example, DirectCD allowed that! |
