Re: Adding MD5 to Image...

2004-08-13 Thread Ashish Rangole
Pardon me if I misunderstand you I wonder if it is possible to
add the checksum of a file to the file itself. Because mkisofs
creates iso image file, appending the md5 sum to the image
defeats the purpose of having a checksum (unless you want to
strip out the md5sum info from the image before calculating its md5sum).
Having said that it, may be feasible to add it to cdrecord etc.

Hey guys..
How hard would it be to have MKISOFS add a line after creating an 
image that had the MD5 sum for that image? i.e. Something like:

Total translation table size: 0
Total rockridge attributes bytes: 268578
Total directory bytes: 0
Path table size(bytes): 10
Max brk space used 1dc784
ISO Chksum: a69def10...190F5
2290963 extents written (4474 Mb)

(I've seen a few(?) patches to have MKISOFS read/write individual 
files IN the image against MD5's, but nothing for the whole image..)

Only reason I ask is that alot of dist's are given with MD5's.. 
Currently I have to create the iso (split-output) twice, first time to 
the files, second time piping it to md5sum.
I know enough 'C' to see where it writes to the file, but not enough 
to even try and mess with it. :)

Ideas? Thanks!
Mike.

Re: Check / verify and test quality of burned CD/DVD's

2004-07-15 Thread Ashish Rangole
I usually calculate the md5sum of the iso image before
writing it to the disc. After successful write I use
readcd to read the iso image back, calculate its md5sum
and compare.

HI,
I would like to know which tools are out there to verify burned
CD's/DVD's and which tools or ways are out there for linux to see
what quality my burned media is. I can verify a burned media with
"cmp". But this doesn't give any information about quality.
Any hints?

Have a look at the readcd manpage. Maybe the -c2scan option may be 
of use?

In order to get a permanent key one has to request Joerg Schilling,
the author. I would also like to have a key for cdrecord-ProDVD for
Linux system. I wonder if anybody has ever had any success in getting 
one from Joerg. Please let me know if anybody has. 

Joerg, I wonder if you can respond to this, letting people know 
about your policy of entertaining the requests for such permanent
keys and the procedure.

Thanks

write verification when using growisofs

2004-03-25 Thread Ashish Rangole
In order to do a verifiable write when using cdrecord I follow
this sequence:
1. I first create the iso image of the data on the disk and calculate
   its checksum. Then I write the iso image to the CD and delete the iso
   image from disk.
2. Using readcd I read the iso image back from the CD
3. Calculate the checksum of this iso image
4. For verification, I compare the two checksums

I am new to growisofs and understand that it does not write 
intermediate iso image to disk but rather directly to DVD. If I have to
write ,say DVD-R, with incremental writes what is the mechanism by which
I can do the verification of each incremental write process. Can it be
done in a manner equivalent to the one I described above or is there a
better way?

I shall really appreciate your response.

Thanks in advance for your time and help.

Multi Volume CD/DVDs

2004-03-18 Thread Ashish Rangole
Pardon my ignorance, but I would like to ask what is the commonly
practiced method of creating multi-volume disks. That is, for instance
I need to burn a directory that has files whose combined size is, say
12 GB. How would one go about creating multiple ISO9660 images from it
and then burning them on CD/DVDs. Is there a way that these images can 
themselves keep track of information like their position in the
sequence, total number of images that constitute the complete dataset
etc.

Also, what if the things are complicated by the existence of one or 
more files of size > 2GB. Is this a Linux only issue? Is this an issue
on 64 bit SGI IRIX systems?

I did read mkisofs man page but could not understand how exactly
to get this done. Please advise. I shall really appreciate any response.

Thanks in advance for your time and help.

Re: Using readcd to read 3rd party discs

Thanks for the response. But I still have couple of

1.isoinfo result and readcd result do not always match. Which one to

  till end?
2.Assuming I decide to use a value for number of sectors, how do I know
  that I should subtract 2 from it (in case CD was written w/o -dao) or
  not before I use it in "sectors=" ? I do not know how and where the CD
  was written (Linux?, Windows? etc).

I shall really appreciate any help.

Re: Using readcd to read 3rd party discs

2003-10-13 Thread Ashish Rangole
Thanks for the response. But I still have couple of
concerns/questions.

1.isoinfo result and readcd result do not always match. Which one to
  choose. Can readcd just tell the number of sectors without reading
  till end?
2.Assuming I decide to use a value for number of sectors, how do I know
  that I should subtract 2 from it (in case CD was written w/o -dao) or
  not before I use it in "sectors=" ? I do not know how and where the CD
  was written (Linux?, Windows? etc).

I shall really appreciate any help.

Thanks
Ashish

Using readcd to read 3rd party discs

2003-10-09 Thread Ashish Rangole
I guess this is a novice level question.

I am planning to use readcd to read from a data CD/DVD. 
I understand that for discs written with "-dao" flag, readcd will
read exact number of sectors, whereas for those written w/o
"-dao" flag, readcd tries to read 2 sectors more than the actual
data sectors causing readcd to fail.

In order to avoid the error at the end of reading I think I should use
"sectors=" option with readcd. For a disc that I haven't written and
thus do not know how many sectors it has, how do I find that out? In
other words, how do I know what value should I give to "sectors=" when
I get a CD/DVD from a thirdparty which might or might not have been
written with "-dao" option?

Is there a better option than using readcd?

Thanks in advance for your help

I guess this is a novice level question.

I am planning to use readcd to read from a data CD/DVD. 
I understand that for discs written with "-dao" flag, readcd will
read exact number of sectors, whereas for those written w/o

In order to avoid the error at the end of reading I think I should use

cdrecord-ProDVD license

2003-07-17 Thread Ashish Rangole
All,

I would like to know if Joerg Schilling does not give
the commercial use license for cdrecord-proDVD anymore.
Please let me know if anybody knows about this because
it appears that for some reason I can't get in touch with
Joerg at all on this.

Thanks for your help.

Ashish

cdrecord-proDVD ,linux and IEEE1394

2003-03-19 Thread Ashish Rangole
All,

I would like to know if anybody has tried burning
CD/DVD in linux on a drive with IEEE1394(firewire) 
interface and if it has been tried with cdrecord-proDVD.

I am thinking of using cdrecord-proDVD on Mandrake 9.0
and the burner is a Pioneer DVD A-04 with IDE to IEEE1394 
convertor in front. I wish to know how IEEE1394 works on
linux in general and with CD/DVD writers having IEEE1394
interface.

Any response will be greatly appreciated. Thanks in advance.

Ashish
