Question

drutil burn -erase -eject /folder/to/copy DOES NOT ERASE

Hi,

I need to automate a copy of a folder on a cd-rw. With time, the cd will fill up so I need to make sure it is erased before burning it. If I try to erase it before the burn step (with drutil erase), the disk is ejected. It seem there is no way to erase a cd without ejecting it... And if I use the command mentioned in the title of the message, erase does not work - the cd fills up and I get eventually a disk full so that no back ups can be done.

I only want the cd to be ejected once the backup has been done (with an erase before the backup).

Thanks anyone for his/her help.

nb: the test is done on a latest mac mini (Matshita CD-RW CW-8124) and the cd is really a -RW

See if discutil will erase without ejecting. Pity you do not have a tray-loading drive.

Have you tried it, macmartin ?

According to the man page, the "erase" option ejects when it is finished -- which is what we do not want here.

Yes, I have.
burn -erase will erase and burn the CD before ejecting it.

If the CD is ejected after burning, you could use

drutil tray close

in the script, if you want the CD to stay inside the drive.

The original poster is using a Mac-Mini which is a slot-loader as opposed to a tray loader. An eject would halt the process.

Oh, I have overseen this.
Anyhow: burn -erase will at least burn the disk before ejecting it.
I hope this helps a little.

No, the OP, using reusable media, wants to be able to erase and then burn in an unattended fashion.

Well, actually he wrote:
"I only want the cd to be ejected once the backup has been done (with an erase before the backup)."
So I thought, this might help.

I cannot blame you for trying to help.

Please excuse me if I seemed a bit harsh, but I am dealing with a real idiot on two other threads and my attitude spilled over.

Let's keep looking. There might be An Answer out there.
