Can't read the CD burned by DR-4A

Hi all,
I can't read the CD burned by DR-4A.
I already tested by any DVD reader and DVD blanks.
What the problem is???
I don't think DR-4A have some encrypt writing feature

dont worry...or
complain
the dr-4 can write only few dvd blanks
and now with the new firmware u wont be able to use clone cd or dvd
complain with them
the problem is the firmware

Can't read dvds burned on the same mac

Hi,
I burn dvds on my macbookpro, but can't read them on the same machine.
This happens since 10.5.1.
Tried both verbatim dvd-r and tdk dvd-r.
A dmesg returns frequently:
jnl: disk2s3: flushing fs disk buffer returned 0x5
which error is it?
any hint or pointer to a solution?
-c.

Hi All
this might sound funny or strange... but it happened to me 3 times before finding the problem.. So just in case here it goes.
If the machine was working fine at one point.. burns DVD with no problem it just doesn't read them..
Let me ask you this question.
Have you fumigated your place lately? or around the time the machine stopped reading the DVD;s.
I use the the foggers that look like smoke.. so they live no residue, no problem with living pilots on.. never had a problem with them
Til I had to replace the DVD drive on my older Mac, an iMac20 .. took 3 replacements for me 2 finally realize what the problem was...
Like I said, just in case.
Good luck

Can't read dvd

I have some dvds I have recorded from old movies in the past. I know the content is good, they play on a dvd player, however, they read as a blank dvd on my imac. I want to edit them...any suggestions. Some of them read...even same brand of dvd...help:-)

Welcome to discussions!
Perhaps it isn't the media you are using, but, instead the manner in which you are burning.
(Thanks to Len Goff for the copy & paste):
Suggest you create a disc image and then burn the DVD. File/Save as Disc Image...
http://docs.info.apple.com/article.html?artnum=164927
This will isolate any encoding/burning issues you may encounter. Once the disc image is created, double-click the .img and burn the virtual disc that should appear on your desktop, using Toast to burn the DVD. Disk Utility to burn the .img file. Usually, you can select a burning speed in Disk Utility.
There are variations to this process based on which OS X you are using...
Open Disk Utility (in Utilities folder in Applications folder), click on the virtual disc (maybe the .img) in the left-hand window. Click the Burn icon. A new window should drop down and your SuperDrive tray will open after clicking the Burn icon. Insert a recordable DVD. (Verbatim DVD-R preferred by me.) Click the Close button. Wait. Select a burn speed. If you hold your mouse cursor over the pop-up it says: "Select a slower speed to work around burn failures," so select 4x or slower for best results. Then click the Burn button.
-->If the virtual disk selection won't allow you to click the Burn icon, use the .img file instead. This may have changed in 10.3.9 and did change in Tiger.
Also, you can use DVD Player to play the virtual disk to check your iDVD project before burning to DVD. Launch DVD Player. File/Open VIDEO_TS (Open DVD Media... in Player 4.6). Find the VIDEO_TS folder and open that. (The audio folder is for DVD-Audio disks.)
http://docs.info.apple.com/article.html?artnum=93006
Burning with the disk utility allows you to burn slower. That means a better play-back DVD.

Satellite Pro M30: Can't read DVDs on DVDrw drive

I cant read dvds...
i can burn them but when i start to read them it shows me an error like this " E:\ is not accessible. The request could not be performed because of an I/O device error."
its killin me, please help

Hi
The I/O device error occurs if drive has a problem with the disc or your system config (mainly a disc problem).
The DVD drive cant read all DVDs or just the burned DVDs?
Which burning software did you use?
As far as I know you should always closed the burning session.
Furthermore if you need the DVD Shrink software please check this links:

Dvd drive can't read DVD's

hi all,
My problem is the dvd drive in my laptop. It will not read dvd's commercial or burnt variety, curiously it reads cd's just fine. So far email tech support has been useless. I wrote them explaining what steps I had tried to fix the problem such as uninstalling and reinstalling device drivers and they suggested that I try and reinstall device drivers. Do they even bother to read the emails you send or just guote out of some manual. System restore did not work either, but the drive is rarely used so the latest system restore points are probably useless wrt this problem. Returning the unit to factory state is simply not an option. The unit is still under warranty. Any other suggestions? I couldn't find any firmware updates. Other than this problem this system works flawlessly and has since I bought it.

The DVD's I assume are data as well as movie files? Do you have an app such as Intervideo,etc to play dvd's?
My usual steps include running a laser cleaning disk, remove/reinstall as you have done and maybe deleting upper & lower filters.Once done if it still doesn't work,it is declared dead.
I would request a replacement.Of course HP will likely first make you jump through the usual hoops which include a System Recovery back to factory configuration.This can be eased considerably by making a backup Image of your current setup to restore later.
A great free tool I have used a lot lately is Macrium.It works fast and will create & save the image to external USB HDD, CD/DVD,network drive,etc.

How to Read DVD using ioctl call

I used the ioctl call DKIOCCDREAD to read the CD content. Is any ioctl call to read the DVD content?
If not, How can I read the DVD content in the MAC 10.5.8?

IMac can't read DVDs

My iMac won't read DVDs. I put a DVD in, and it gets ejected after a few minutes. I already tried repairing disk permissions, resetting SMC, using a drive cleaner, trying different brands of blank DVDs, etc. but none of these work.

Contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine.

Beginner question - Can't read nor write a file using NetBean...

Hi ,
I'm a beginner java programmer, I got trouble when it comes to read or write a file program..
I tried 3 programs and all of them can't read the file I want to read, eventhought I have put the txt file in the same folder with my source code.
here is the source code I got from some site
import java.io.*;
class FileReadTest {
public static void main (String[] args) {
     FileReadTest f = new FileReadTest();
f.readMyFile();
void readMyFile() {
DataInputStream dis = null;
String record = null;
int recCount = 0;
try {
File f = new File("mydata.txt");
FileInputStream fis = new FileInputStream(f);
BufferedInputStream bis = new BufferedInputStream(fis);
dis = new DataInputStream(bis);
while ( (record=dis.readLine()) != null ) {
recCount++;
System.out.println(recCount + ": " + record);
} catch (IOException e) {
// catch io errors from FileInputStream or readLine()
System.out.println("Uh oh, got an IOException error! " + e.getMessage());
} finally {
// if the file opened okay, make sure we close it
if (dis != null) {
     try {
dis.close();
     } catch (IOException ioe) {
I also have tried another from book , both of them give the same result, can't read the file...
Please help me with this...
Thank you very much

To start with use the full path to the file
i.e. File f = new File("c:\\the\\full\\path\\to\\your\\file\\mydata.txt"); // Assumes a Windows platform using the C drive
Then check to make sure you fiel exists e.g. System.out.println("File exists = " + f.exists());
You can even test to see if the file is readable but since you created the file this porbably is not required.
