Why so long to copy CD files?

Archived from groups: comp.sys.ibm.pc.hardware.storage,alt.comp.periphs.cdr,comp.publish.cdrom.hardware,microsoft.public.windowsxp.hardware (More info?)

It takes a very long time to copy some files from a CD onto my hard
drive.

I am using WinXP Pro with two year old LiteOn LTR-40125S CD drive.
The CD has 650 MB of data in approx 14 files (see blist at bottom).

Using Windows Explorer I dragged the files on the CD onto my hard
drive. To do this the CD reader worked for about hour in 3 second
bursts, each time with the odd flicker of CD-R's LED.

On the other hand when I used Nero to burn a copy of this CD it
took only 2 or 3 minutes to read and make an image file of the
whole CD.

(1) What is causing this short-burst copying to happen? Is it XP,
the CD-R hardware, copy protection on the CD, the CD's file
structure, my PC's configuration?

(2) And how can I get the files from this CD to my hard drive more
quickly?



btbus.dat 50 MB
d5.dat 15 MB
d5.idx 0.9 MB
d7.dat 4.8 MB
d7.idx 1.3 MB
dbbus.dat 62 MB
icd.dat 0
lobdesc.dat 17 MB
lobdesc.idx 0.2 MB
uk.dat 403 MB
ukaddr.idx 124 MB

I don't think that is the case, as the OP mentioned that he could read
in and create an image of the whole cd in 2 or 3 minutes.

Did Mikey snip these accidentally?

Did you snip accidentally, Mikey?

Nope, the hard drive led wouldnt flash ocassionally if it was.

Is there a way I can extract the files from the large "image" file
which Nero can be asked to create on my hard drive?

And when the CD is read too since it flashes for all drives.

Yes, but if there really was a traffic jam on
the IDE bus, it would be on all the time. It isnt.

But the point here about the IDE traffic jam is this- Is your hd and
cd on the same IDE channel? Lights are indicators, but you really
don't know or will not know unless two things- a.) you see in the
bios, b.) you see in on the bios result screen after post (and it
may flyby too fast to read, these days anyway if u have a fast
machine, or c.) You open your case and find out, and d.) this is four
things now, not two.

Many off the shelf out of the box pc's w/one hd and one cd come from
the factory setup w/HD on chnl 1 and CD on chnl 2, because it is the
way u want it and they'll do it that way, but until u verify this, u
truly don't know. Meanwhile, if u find HD and CD on same chanl, split
them and you certainly will gain speed, and in every situation, by
design.


Hope it helps,
