 Posted: Tue Sep 12, 2006 12:43 am Post subject: 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?

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.

I have him Killfiled. I suggest you do the same. If you feel compelled |
to respond, please don't quote him in your response. It sort of defeats
the killfile, I don't care to read his posts that's why I killfiled him
in the first place.

I've been hanging out here for almost 3 years. No one has come close to
smh when it comes to helping folks sort out problems. On the other hand,
I think his stream of rants is having a serious negative impact on the
viability of the group. I've suggested that a weekly "Mikey FAQ" would be
more effective than the "stream of rants" concept, but he doesn't see it
that way. Oh well.
Still, smh offers useful advice while Mike offers condescending
comments that are generally useless, and often based on ignorance.

Some of us have been here longer and have smh killfied longer than that. We
don't see his garbage unless someone like you repost it. smh is
knowledgeable but that knowledge doesn't make up for his vitriol.
As for Mike, I have always found him to be extremely knowledgeable. His
posts are rarely useless and never ignorant.

Well, I'm sure a biologist could find some redeeming features regarding
mosquitoes, but most of us just want to kill them and that's what we do
with SMH, put him in a killfile. Unfortunately, there seems to be a
loophole in ng clients whereby our best efforts are defeated when people
insist on quoting his rants in replies. The upside of their doing so it
reminds us of the wisdom of our decision to killfile him in the first place.
Dave Cohen
The problem with SMH is that none of his advice or help or knowledge that he |
tries to share with others is earned or learned by research on his own , he
stole it from others. He's like a broken record, he butts in on EVERY ***
thread no matter what the subject when it comes to CDR or DVD-R etc...
And to top that off, he reposts the same post 6-7 times over a 5 hour period
as if his mentally challenged brain took a dump. It's as if he forgets that he
already posted the same message. I also have 0 repsect for someone who hasn't
held a job in years and lives off the work of others. He is online almost 20
hours of the day. |
