CD-RW UDF, "Fixed Packets" - the history and the future!
Hi,
When CD-RW drives first arrived on the scene it was suddenly possible to drag and drop files from Windows Explorer onto the CD-RW drive and to carry out operations similar to a Data Stick or floppy. You didn't have to create a "CD Project" or "burn" the CD. To me, this was much more interesting than using CD-R with Nero, but for some reason not many people were interested. The power of drive letter access, is that you can use APIs to work with your CD - e.g. you can create a batch file with a few lines of code that will automatically back up your data (but only the files that have changed since the last backup). The first CD-RW drive I owned was a Philips CDD3610 2x, it came with Adaptec Direct CD and I was running NT4 at the time. I used to do all my backups to CD-RW in UDF format and everything worked perfectly. After I moved on, the old Philips drive was put in my Dad's computer, and he used it for YEARS with weekly backups, first with Win95, then with Win2k - again not a single problem. Around the same time I got rid of the Philips, I also got a Yamaha 8x, 4x, 8x drive for work and we were running NT4. I created a batch file and the Admin staff had a button to press to do the backup. They used this for YEARS, even after I left it was still working, and not a single problem. Shortly after this, I upgraded to a Plextor 12/10/32s and got the 10x CD-RW media to go with it and also moved to Win2k with DirectCD (this was around the time it became Roxio). I did all my backups to the new 10x media, everything seemed to be OK, but months later I was having MAJOR problems with all my CD-RW disks. There was all kinds of confusion in the newsgroups regarding the cause; bad media, "fixed packets", Roxio incompetence, UDF is broken, Win2k incompatibility, etc. etc. The errors I was seeing were both block level AND FileSystem level. I later upgraded to Plextor 48/24/48, started with new 24 speed CD-RW media, did all my backups, months later, more problems but not so many. Up until this point Ahead's InCD was COMPLETELY broken. Something else changed at this point - suddenly Mt Rainier (MRW) came on the scene. In some ways, the MRW spec is designed to deal with the POTENTIAL shortcomings of "fixed packets"; as I understand it, fixed packets don't have the same low-level error correction capabilities we see in Audio CDs and Mt Rainier is supposed to address this. HOWEVER, I found MRW to be completely impractical for day-day use. Every time you insert the disk there's a massive delay as it's starts formatting and verifying. I then got three Plextor Premium 52/24 drives, two at work, one at home, and upgraded the firmware. I also noticed InCD suddenly works! I disable MRW in both properties screens and set it to UDF 1.5 I then tried a lot of CD-RW UDF backups and data transfers, both at home and at work. A year later, not a single problem. Even media that was "bad" in the past is suddenly reliable. I then tried Plextor P750A, and again everything is working perfectly with CD-RW and UDF and I now want to try DVD-RAM. So, I don't know for sure, but it looks like the major problems I was seeing with CD-RW and UDF may have actually been related to the optical drives themselves, as opposed to the software or media. Could it be the drives of that era were just not very good? -- Gerry_uk |

That has little to do with the software. The faults of fixed-length packets are in the format, not in the specific software which implements UDF. the overwhelming majority of the complaints about any UDF software are about the format, but the format is seen through the software which gets the blame. I have used only DCD for packet writing, have had no problems due to the software - but too many due to the format itself to bother with it any longer. ------------------------------------------ .. ---------------------------------------- Mikey, you are The Slimiest Friggin SOB! ---------------------------------------- Mike Richter, were you born with "Scam Artist" emblazoned on your face? -------------------------------------- (Mike Richter, any Material Connection w/ Roxio?) |

Could it be the drives of that era were just not very good? I've never had much of a problem with udf either Roxio or now with DLA. I had poor results with 24x rw media and don't use it. I also no longer use dla very much, a flash drive is suitable for home differential data backup and I master the full file backup. I use imaging for os backup. One thing I've learned is to be selective about what one should read (believe) in ng's, particularly this one. It's my belief that much of the posting is a recycle of previous posts. Dave Cohen |
