Slow copying of files from CDR ... |
|
|
Hi,
Used Nero 6 and compiled a data CD at home on a Plextor 16/10/40 cd
writer. Data mode used was Mode 2/XA. Data was burned successfully with
buffer uderrun being avoided 184 times!
CD then used at work in a different machine to copy all files to hard
drive and it took about 30 minutes to copy the files!
Does anyone have any ideas why it should take so long to copy these
files (458MB total)?
What is the difference between Mode 2/XA and Mode 1 data modes and when
would I use them? Have I used the wrong mode for this data CD?
TIA.

Next time reduce the burn speed, defrag the hard disk, clean out the
Windows\Temp directory.

Reread many times to correct errors. Examine the cd with Nero Tools, CD
Speed, Extra, Scan Disc. Bet you will see many yellow squares.

Wouldn't have made any difference. But use Mode 1 because it's easier
to be recognized.

Check your DMA settings as any half decent PC should be able to burn without
invoking buffer underrun protection. You have a bottleneck somewhere.
As for the slow read, the likelihood is that have created a poor burn (maybe
inappropriate choice of media and or burn speed) and that the other machine
is having a hard time reading the disc. Or the drive on the target PC may
simply be old and slow or a DVD drive that has problems with CD copies. The
mode here is not relevant, but if you right click the mode selection in Nero
you will get an explanation of what the various modes are.

Have already tried reducing burn speed, I have a smart schedule set
using Diskeeper to regularly defrag the hard drive and I always make
sure the temp directory is clean.

So this would be the general setting used for most burns yes?

It's quite an old pc now ... PIII 450 built in 1999. How do I check DMA
settings and what should I be looking for please?

I have used Sony CDR 700MB that I purchased from Woolworths a few months
ago. I was told these were decent quality.
It may be that this machine is struggling to read the CD here at work as
this is quite old.

Operating system? DMA is a property of the IDE controller and is
configurable separately for primary and secondary devices. With Windows 2000
and later, see http://www.gmayor.com/cd_writer_udma_mode.htm.

Mode 2 should work as well as Mode 1, though I prefer Mode 1 even for
multisession discs. The problem is clear from the underrun protection:
you're trying to write at too high a speed. Cut the nominal write speed
down until few or no buffer underruns occur. The write time will go down
and you will probably have fewer errors. (Buffer underrun protection
does not produce errors in itself, but it tends to go with a high error
rate.)
In any event, check the written disc for errors using CDSpeed, CD/DVD
Diagnostic or a similar program. You may want to change medium to get
the errors down so reading is quicker - and so all remain recoverable.
When an error is encountered, the sector is re-read until a valid datum
is found. Rereading is very slow since it requires seeks.

You didn't mention the age of the reading machine. Some older readers
have trouble reading CDRs. You might want to try it on a different PC
to see if it's a disk problem or a reader problem.
I burn all my CDRs at half the max burner speed, both because it makes
them more compatible with older readers and because they last longer.

How many files? THe number of files make a huge diffeence.?

Yes. Nero wants to use Mode 2 when you mix audio and data and will
prompt you a warning. You can disregard the warning. |

======================
From: Mike Richter (Slimy Friggin Shit)
Mode 1 was the original format for data recording and
did not support multisession.
======================
(Incat Systems, 1994)
Multisession discs are recorded according to the Orange Book Part II
standard, which states that they can be written in either the CD-ROM
or CD-ROM XA physical format. It does not matter which; theoretically,
you could even mix the two formats on one disc.

I though BURs would potentially lay down more errors in the disc?
Cant see any other way it would correlate with more errors?

Have now checked the CD with Nero CD Speed and it gave me two yellow
blocks denoting "Damaged".
I would imagine I'm aiming at getting all the blocks to appear in green
("Good")?
Should I try writing another disk at a lower write speed again?
Thanks.

It's a few years old by the looks of it. Will try on another PC.

Yes, I dropped from 16x to 8x and all seemed fine until I used Nero's CD
Speed tool and it gave me 0.32% damaged.
