Blanking DVD+RW: Mepis 3.43 vs Mepis 6.0 - What changed?
I recently upgraded from Mepis 3.43 to Mepis 6.0.
In Mepis 3.43 I could enter konsole and enter the following command to blank (not format) a DVD+RW:
growisofs -Z /dev/scdN=/dev/zero
Side Note: Where scdN = your device mount point
However, this command doesn't work in Mepis 6.0. The DVD+RW does not blank: It remains full. Here is the output of a recent Mepis 6.0 attempt to blank a DVD+RW (the beginning text is different than it was under Mepis 3.43):
Mepis 6 gives the same output as yours for growisofs --version
What she is doing here is bit copying zeros on to a DVD which ends up then I assume covered in zeros
Don't know why -You would be spending a lot of time waiting as it wrote data (zeros) all over the disk . If you are just putting new stuff on it a format is enough and quick
K3B formats a DVD and it would then be ready to write data all over it (After format the addressing data at the front of the disk points to nothing , but the old data is still on the disc but unaccessible and is later written over when you put new data on it )
So the command "growisofs -Z /dev/scdN=/dev/zero" issues the below command which gives a warning as so
"WARNING: /dev/hdd already carries isofs!
About to execute 'builtin_dd if=/dev/zero of=/dev/hdd obs=32k seek=0'"
the command built into growisofs is "dd if=/dev/zero of=/dev/hdd obs=32k seek=0"
You can look up the manual entries for this with
Note the output file above is going to "of=/dev/hdd"
Which is not where you want it to go or at least it is not /scdN is it?
I get a feeling /dev/scdN is a link pointing to /dev/hdd -maybe your problem is in there
I see you posted just after me and it fixed itself .
