It took less than a minute to create the ISO image file.

You can find a link for downloading Knoppix 4.0.2 at http://www.distromania.com/distro_info.php?distro=332

I think possible reasons for I/O errors are a dirty or damaged DVD-ROM medium and a dirty DVD-ROM drive.
You could try to clean the DVD with water and some dishwashing detergent.
If there are serious scratches you could try some polishing paste that is intended for the repair of CD or DVD surfaces.

Hi,

I have always used a bloated windows app to verify ISO integrity.

Q: Using Knoppix 7.0.3 LiveUSB, what is the correct indexing used to check the following MD5:

KNOPPIX 4.0.2 MD5_Sum:
1188f67d48c9f11afb8572977ef74c5e

Thanks for getting me wise to the archive of all Linux Distributions, klaus2008!

luther

In the terminal you can use the program md5sum

Code:

---

md5sum KNOPPIX_V4.0.2CD-2005-09-23-EN.iso

Dear klaus2008:

Once I pluged in the complete path, verification proved a valid ISO:
Q: Is there a way to see which directories are in the path?
I thought the 'Desktop', by default, was.

Q2: Can 'Desktop' be added to the path?

Code:

---

knoppix@Microknoppix:~$ md5sum /home/knoppix/Desktop/KNOPPIX_V4.0.2CD-2005-09-23-EN.iso
EXP: 1188f67d48c9f11afb8572977ef74c5e
ACT: 1188f67d48c9f11afb8572977ef74c5e  /home/knoppix/Desktop/KNOPPIX_V4.0.2CD-2005-09-23-EN.iso
knoppix@Microknoppix:~$

Finally got some hard data to work with, thanks!

Dear klaus2008:

Does this dialog compare to what you are familiar with:

I'm geting a sense Linux has compatibility issues with this burner:

Vendor_info : 'PIONEER '
Identification : 'DVDRW DVR-K16 '

The reason being I get the LiveCD to boot initially, then down-the-road, the boot freezes!

Your feelings?

Hi,

The created ISO did boot OK, BUT shutdown sequence trapped this error:

Code:

---

# ./etc/init.d/knoppix-reboot: line 51: /usr/bin/usleep: input/output error

---

I have never had this problem with Knoppix LiveUSB.

Q: Can this LiveCD be converted to a LiveUSB?

Regards,
luther

Do you still get the I/O error if you use the cheatcode acpi=off ?

Code:

---

knoppix acpi=off

There are two kinds of paths. The first one is the search path used by the shell to find an application. This path can be shown by issuing

Code:

---

echo $PATH

---

The other kind of path is specific for an application. There are programs using a list of directories wherein they look for data files, but in most cases a program must be told where it finds the files it has to work on. Usually the data search path of an application is defined in a configuration file. The program md5sum does not use a configuration file or an environment variable for the data search path. Therefore you have to describe the path of the data file if it is not in the current directory.

[QUOTE=klaus2008;129319]

Code:

---

mkdir -p /media/sda1/knx402/master

Hey Klaus2008!

The code you posted above, only creates the '/knx402' directory, using Knoppix LiveUSB 7.0.3!

Shouldn't it have crested the subdirectory '/master', too?

luther

The command 'mkdir' creates a directory. If you use the switch '-p' the program creates missing parents if necessary. Thus the command

Code:

---

mkdir -p /home/knoppix/dir1/dir2/dir3

---

should create the directory dir1 in the home directory, a sub directory /home/knoppix/dir1/dir2 and a sub sub directory /home/knoppix/dir1/dir2/dir3. The command

Code:

---

ls -Rl /home/knoppix/dir1

---

should show the new directories.

Code:

---

mkdir -p /media/sda1/knx402/master

---

Hey Klaus2008!

Could you run the above code in a root terminal and post your keystrokes?

It appears this HDD only acceps the first directory.
