[SOLVED] Blank dvd not being detected

matiasar · 12-10-2010, 09:55 AM

I'm having this weird problem and still I can't solve it.

I'm using Debian Squeeze and when I insert a blank dvd to burn it the disk is not detected.
If I insert blank cd, audio cd or already burned dvd it works.

My dvd burner is Asus. Might I think the problem is related with hardware (burner) and I may try replacing it? Or I could test through software to check if hardware should work?

I'm running 2.6.32-3-686-bigmem kernel.

This is lshw output:

I would first try different media. Your media may be wrong for the drive or just too cheap to work.

matiasar · 12-10-2010, 02:47 PM

mlangdn,

thanks for your reponse.
I forgot to mention, I tried with two different media (both Sony and Verbatim dvd.

EDDY1 · 12-10-2010, 02:50 PM

Did you try cleaning optical lense?

jefro · 12-10-2010, 04:50 PM

A live cd to ram or a usb booted OS would help prove either or. Burn something in some other OS or version.

matiasar · 12-10-2010, 07:48 PM

Thanks folks.
Yes, that's what I thought. I booted using Ubunto 10.10 from live-usb. Same problem occur, so I tend to think this problem has nothing to do with software, it seems to be hardware related. Think I'll try to get another dvd burner to test.

Regards,
Matias

Today I discovered the problem occurs also when trying to read DVDs. Audio CDs, for example, works without any trouble.

Does anybody knows if could be a problem with libdvd? Should I still think the problem is hardware related?
I don't have any winblows to try if the same problem occurs.

Thanks in advance,
Matías

1) Use another DVD burner, so you will know if the problem is software or hardware. Using another DVD burner, if not more trouble then it is certain that your DVD burner is bad ...

2) If it's hardware then it might be the psu. It may seem strange but I have noted cases of bad runs in DVD burner caused by the psu ...

3) dvd burner is bad ...

Good Luck

In the cdrom/dvd hardware, there are 3 adjustables which are very fussy adjusting the read head. They are set at manufacture, and then sealed.

Over passage of time, these settings may drift (esp. on cheaper drives) and as a result, sensitivity lessens. It's only going one way - into the bin. The choice is yours as to when that happens. Symptoms are: Not recognizing cdrs/dvds, notfinishing an audio cd (losing track and restarting at track 1. I did get an extra 6 months out of one hi fi by going at them myself, but it was more trial & error than good judgment.

Repair is not possible because the equipment required to set up has to examine laser o/p and is hugely expensive. So nobody can make it pay. Even sending the drives somewhere to have it done isn't viable either.

thanks a lot for your comments fellows.
As soons as I can replace the burner I'll post the confirmation. Everything tends to show it's a hardware related problem.

matiasar · 12-13-2010, 07:28 PM

Fellows,

As supposed to be, there's nothing wrong with Debian.
I tried with another burner and everything goes ok, so there's a failure with my original burner.

Thanks for the suggestions and comments. It's been very enlightenings. Regards,
Matías

At least optical drives are way cheaper than they used to be - glad its resolved.
